What are the possible phenotype(s) of the offspring?

(Brown hair (A) is dominant to blonde hair (a).)

What are the possible alleles a parent with the GgBb genotype could donate to their gametes? (Hint: F.O.I.L.)

What genotype is missing from this Punnett Square?

Round (R) and yellow (Y) are dominant traits. Based off this Punnett square, what fraction of the offspring will have wrinkled, yellow seeds?

Black fur in mice (B) is dominant to brown fur (b).

Short tails (T) are dominant to long tails (t).

What percentage of the offspring of the cross BbTt x BBtt will have black fur and long tails?

What fraction of offspring from the cross AaBB x Aabb will be heterozygous for both traits? (Write out the Punnett square.)
