Extra Credit Lab Question

Honors Biology Extra Credit Lab Question 

Logical Reasoning:

It appears that the mother of the pups is yellow. Using this information, I deduce that the mother is probably dominant for Melanin production. However, some of her puppies are black and others are brown, so the mother was probably not dominant for color. This would mean that her genotype would have to be either ccMm or ccMM. The puppies were all dominant colors for color, so the father was homozygous dominant for color and heterozygous for melanin production, which would mean that the mother would also have to be heterozygous for the melanin production to get the colors of pups that were created.

Results: 

Mommy = ccMm

Daddy = CCMm

Conclusion:

These results are the only possible combination that I was able to find that would make sense for the color of puppies that were generated from the information provided about

The Honors Bio Rapture is Coming

We spent last class reviewing for the test and discussed the 20 point essay that we will have to write, which will connect DNA Replication, Protein Synthesis, Cell Organelles, and the Cell Cycle. I am very nervous for this test, but feel as though I can possibly do okay on it. Only time will tell if Adam Holliday can pass his last test of the semester.

THE RAPTURE IS HERE!!!

No Got No Time No More

I am sorry, but this is going to be a lazy blog. 

I don't have time to write great works of literature anymore.

Why are the ends of semesters always so brutal!

Ahhhhhhhhhhhhhhh!!!

Your Inner Fish Chapter 6

Your Inner Fish Chapter 6

This Chapter focused almost entirely on embryology, which is the study of the development of embryos that go through the process of fertilization and become adorable fetuses.


The Chapter also mentioned the three germ layers: endoderm, mesoderm, and ectoderm. These three different tissue layers help protect and nurture the embryo during its growth process.



This Chapter focused on the developmental
processes in different types of embryos and connected this to previous evolutionary topics we have been over in class.

Life's a Test

So...

We just took our fourth test of they year...

and it went pretty well...

But...

Apparently we have another test next Friday...

and an enormous assignment due...

But it will be break in less than two weeks...

Genetics Test Review

Honors Biology Blog

Genetics Test Review Day

There is not very much to talk about that has not been discussed in my previous blog. Today in class we took a short quiz and then spent the majority of the class reviewing for the test. One concept that was clarified for me was sex-linked genes.

Say for example that a female alien with pink eyes is mated with a male alien with green eyes and we are to determine the offspring. (Pink eyes are X dominant). How would we solve this?

First, we would put the female on top of the problem, which would be XPXP and the male on the bottom would be XpY.

We would then solve the problem and find the offspring to be XPXp, XPxp, XPY, and XPY. 

I feel very prepared for the test tomorrow and am excited for what the future holds.

Research Lab

Today in class we continued our studies of genetics and advanced onto something that none of us had though of before...

Co-Dominance 

This is the first time that we have had to do problems involving traits that are not recessive and dominant to each other, rather the traits are co-dominant and can both show in the offspring. The example that Mr. Quick used to explain this unusual concept to us was Labrador Retrievers. The multiple shades of labs that are available on the market of dogs are largely due to co-dominant traits. This co-dominance allows for there to be white labs, chocolate labs, brown labs, black labs, and even silver labs.

But how does this happen?

A co-dominant trait occurs when there is a condition in which both alleles for a gene are expressed when present. This occurrence can be referred to as the "blending" of traits; however, there are other examples of alleles not solely being dominant or recessive.

Examples

Co-Dominace - Red X White = White/Red Spots

Incomplete Dominance - Red X White = Pink

Conclusion

There is still a lot to be learned about co-dominance in genetics, which we will cover next class. In the meantime, enjoy this beautiful specimen known as a Silver Lab!

I Should Have Done this Blog before Break...

Meiosis

Today in class in order to better understand the process of meiosis we used popsicles sticks to represent the genes that carry the different traits. We then performed the process of meiosis with the popsicles sticks and thus understood the process much better. 

Two Trait Crosses

We also tackled genetics problems involving 2 Traits. Mr. Quick taught us two different ways to do the problem. One of the ways is often used by Mr. Fitz; however, I found this way to be very confusing, so I stuck with the normal ways of doing the problem. All in all, if I had to sum up this class I would have to say that we covered a lot of material, but I feel as though I gained a solid understanding of most of it!

I really should have done this blog before break...

My bad...
