Create a baby!!

My partner Morgan and I decided to have a baby together.... Long story short we looked at our facial features to assume what our kids might have. 

Below is a list of traits we have. I decided be the mom and Morgan wanted to be the dad. Haha. By the way we are girls. 

So we flipped a coin to decide what the baby will be and it was a boy and his name is Kegan a mix of morgan and kelsey. 

Basically we flipped a coin to decide what trait was dominate for each of us. In the picture below you can see the out come of trait that came out. This blog post about genetics and how they work and what that they do. Genetics are the part of a person that is found in the DNA. Genes a person get from their mom and Alleles they get from their dad and which one you get is luck and genotypes.  Each genotype has a chance to be dominant and a chance to be recessive gene. Alleles are characterized in letters uppercase letters means that the gene is dominant lowercase letters means it is a recessive gene. With what ever you end up with is mosly likely chance or just genes.

After we finished flipping coins we had to draw what our baby would look like by what our traits look like. This was a really fun and simple project. Below is a picture of our baby.

My Family Pedigree!!!

This is my family pedigree of a PTC paper taste testing. I only tested my Dad, Mom, Brother and I, and above my parents are my grandparent whom I didn't test so they are unknown. Out of the four of us we tested the PTC. My idea of what it tasted like was acetone, my mom agreed with me because we have painted my nails but, my Dad and Brother thought it tasted like a mixture of gas and carburetor cleaner. Concluding this would be a Dominant trait because it doesn't seems skip a generation when tested. Sorry its so small my family lives farther away... Someday I would like to see more family members tested to see if it is a really Dominant trait. 

Meiosis

Have you ever wondered how a baby was created? Its not brought to you by a stork but it is created by Meiosis.

Meiosis is very different from mitosis. Meiosis involves one replication of the genetic material in the chromosomes, followed by two divisions of that genetic material. Therefore, the genetic material is reduced by half. The result of meiosis in a diploid cell is four haploid cells.

Meiosis deals with the sexual reproduction of life. This process is the same one that makes your baby:) How meiosis works is when the sperm of of a man is entered into the egg of the woman. When this happens it creates the babies embryo and and all the important cells and stem cells. (These steps is between the fertilized egg and 22 weeks) After it divides and creates the important cells it goes on to create the "baby". This is where the baby starts to look like a little tad pole because it is just making the skin and essentials like the heart and lungs and this is around 36 weeks. After the little heart beat is created it starts to look like a little human being which is amazing to watch how the child grows. We watch a video in class called "Life Greatest Miracles" which followed a woman who was pregnant and showed what happened when a woman is pregnant. What was interesting is when the body realizes that  something foreign is inside a woman the white blood cells try to get rid of it by attacking the little "baby" embryo which causes the woman to get "morning sickness". If the white blood cells do attack the embryo to the point of nothing that can cause a miscarriage or another way is the egg not making it to the flopain tube correctly. The rest is just a longer time of creating a baby:) But that sums up Meiosis.

HERE IS A VIDEO FROM KAHN ACADEMY. This is a great site and it is easy to understand and follow.

Genetic Organizer

Here is a graphic organizer of Genetics:) 

Homozygous has 2 of the same alleles so in an equation it would look like ee or EE.

Heterozygous is 2 of the different alleles so an the letters would be Ee. 

So E= 2 and E= 1. Genetics is really easy. This graphic organizer is just some vocal and a little review of what we've learned in the past. 

Onion Root Cell Virtual Lab and Lab and Meitosis

Here is a copy of the virtual lab write up and actual onion root lab. This was a pre-test to what we will need to be looking for in the actual lab. What we are looking for is the differences of Mitosis in an onion root cell. You have EARLY PROPHASE AKA INTERPHASE, PROPHASE, METAPHASE, ANAPHASE & TELEPHASE. 

Early Prophase is where the cell has a dark colored nucleus in the cell. Just like the one in the picture above.

The next is Prophase it is similar to early prophase but in prophase is where the nucleolus has disappeared and duplicated chromosomes are visible. Centrosomes begin moving apart and spindle and spindle is in process of forming.
THIS IS A PICTURE OF PROPHASE. As you can see the nucleolus has dissappeared and duplicated chromosomes are visible.

After Prophase there is Metaphase. This is where centromeres of duplicated chromosomes are aligned at the center if the cell also called metaphase plate. The kinetochore spindle fibers attached to the sister chromatids come from opposite spindle poles.

<------METAPHASE 




Anaphase follows after Metaphase and Anaphase is a really cool step in Mitosis. Anaphase is where the chromosomes move toward the spindle poles. Anaphase is the phase where the chromosomes look like fingers.

<---------- ANAPHASE

Lastly there is Telophase this is where the cell divides and the daughter cells are forming as nuclear envelopes and nucleoli reappear. Chromosomes will become indistinct chromatin. This this the step where the cell splits in half and starts the process of Mitosis all over again.

ONION ROOT TIPS AND THE CELL CYCLE


In this activity, you will calculate the lengths of the various phases of the cell cycle in an onion root tip. First you will view some slides and graphics of onion root tips provided by the Molecular Expressions Photo Gallery. Then you will complete the online activity provided by the Biology Project at the University of Arizona.

Part 1.

Use your browser to go to Molecular Expressions Photo Gallery: Mitosis

http://www.microscopy.fsu.edu/micro/gallery/mitosis/mitosis.html

Notice in the micrograph at the top of the page that there are cells in a variety of stages. View the onion slides in this section, then click on "mitosis" in the sentence "Learn the steps in mitosis ... " This will take you to a Java tutorial.  Keep in mind what you have learned here as you proceed to the second part of the activity.

Part 2.

Use your browser to go to Online Onion Root Tips at

http://www.biology.arizona.edu/cell_bio/activities/cell_cycle/assignment.html
Begin by reading the description of the five major cell phases. You will need to keep this information in mind during the activity.

Make a copy of the data sheet that appears on the second page. You will need it to answer the questions.

Proceed through the activity, identifying the phase for each cell you are shown. Pay attention to the hints if you misidentify a cell at first.

When you have completed the activity, answer the following questions:

1. What percent of cells were in interphase?
The percent of cells that were interphase is 56%
2. What percent were in mitosis?
44% of cells were in mitosis.
3. Which phase of mitosis takes the longest?
Prophase is the phase of mitosis that takes the longest.
4. During which stage is the nucleolus visible as a dark spot?
Interphase is the stage the stage where the nucleolus that has visible dark spots.
5. How can you recognize a cell in metaphase?
You can recognize a cell in metaphase is where you can see the chromatids.
6. How might you figure out how long (in minutes and/or seconds) each phase of the cell cycle takes based on the data from these onion root cells? Explain your logic and show your calculations and results below.







7. Produce a pie chart in Create-a-Graph that shows the relative lengths of each stage of the cell cycle in these cells including interphase and each stage of mitosis. You can embed the graph here or directly in your blog.

REAL ONION ROOT LAB WRITE UP

For this actual lab write up, it is actually the same as the virtual lab EXCEPT for the fact that we had to look through a microscope at a real onion root cell. We counted all the Interphase aka Early Prophase, Prophase, Metaphase, Anaphase and Telephase.

Here is the graph of real data that we found in the onion root lab.

FOR ALL THE TWILIGHT FANS!!!!

"THE GOLDEN ONION"

What You'll Wish You'd Known

I actually liked this speech. One reason is he spoke the truth and brought up points that I haven't really thought about like what do you want to do in your life. As a high school my opinion really varies with what I want to be like I have an idea but it changes every now and then so when people ask I usually say Im not sure. Another point he brought to my attention is don't rush being young. At my high school we can take concurrent classes for college credit and sometimes I feel like I'm being rush into adulthood   sometimes I feel so pressured to do everything perfect and sometimes I wish I could be a normal high school student but then I think I chose my paths and they are what I want and I'm proud of that and proud of what I'm doing I feel like I'm going somewhere in life. So as an end I would just like to say his speech is really good and just makes a student think.

Here is a link to the speech :) http://www.paulgraham.com/hs.html
