Week of February 23-27

I was absent for Monday-Wednseday so not all of this might be accurate.
So this week we learned more about genetics. We can now somewhat predict what the eyes or hair might be. We use alleles that stand for the kinds of genes. There are three combinations of alleles. Two of them are used when we are talking about homozygotes (purebreeds) which are written like this BB or bb. With a heterzygotes (hybrid) it looks like this Bb. The uppercase letter is the dominant gene. The lowercase letter is representing the ressecive gene. For example if you're talking about right and left handed the right handed gene might be the dominant gene so it would be the uppercase letter. The left handed gene would then be the ressecive gene so it would be the lowercase letter. We also learned how to chart these to see what the off spring might be. I don't know how to put one of the squares on the blog so I can't show you. So everyone have a nice March.
