Question

In guinea pigs, dark hair (D) is dominant over light hair (d) and curly hair (C) is dominant over smooth hair (c). Complete a dihybrid cross for parents with the genotypes: DdCc × DdCc and answer the following in complete sentences.
Describe how you would set up a Punnett square for this cross.
List the likelihood of each possible offspring genotype.
List the likelihood of each possible offspring phenotype.

Answer 1

You would put DC, Dc, dC, and dc along each side, like so:

then complete it and calculate the probability. I am NOT completely answering the questions, but if you need help calculating the possibilities, you can ask me. ^_^
