1. Model: Scientists use a Punnett square to model the different possible offspring
genotypes from a parent pair. The parent genotypes are written across the top and side
of the square, as shown. The four possible offspring genotypes are then filled in.
The first square is filled in for you. Fill in the remaining squares.
A. What are the genotypes of the offspring?
B. What percentage of the offspring will have black fur?
C. What percentage of the offspring will have white fur?
