Question:

what is a punnett square?

Elizabeth P.
Answer:

A Punnett square is a visual representation of the genetics to see the chances of a child carrying the same genes as one of the parents. You usually put the mom's allele's to the left and the Dad's alleles across the top. Then it is like a multiplication chart - you draw them out. So if mom had TT and dad has Tt then you would end up with TT and Tt for the first two rows and TT and Tt in the bottom two rows, showing that there is a 50% chance for homozygous TT and 50% chance for heterozygous
