Baby steps through the punnett square

This is a place for some serious practice with a very useful tool for completing genetics problems, the punnett square (p-square for short). the basic naked p-square looks like a window pane : aaaah, reminds me of my bedroom window when i was a kid. the very window i would peer out on snowy mornings and hope to myself:"snow day, snow day, snow day" Baby steps through the punnett square (get it?

punnett squares

punnett squares often times, people will refer to a trait or characteristic such as eye color or hair color as being genetic, but what does the word genetic really mean? genetics is termed as the study of heredity and how traits in offspring are based upon those of the parents. heredity is the process in which traits (characteristics that can be...
