Fur color and eye color are inherited traits in panthers. Tan fur (T) is dominant to black fur (t) and green eyes (G) are dominant to yellow eyes (g). The alleles for black fur and yellow eyes are recessive.
If a male who is heterozygous for tan fur (Tt) and homozygous recessive for yellow eyes (gg) mates with a female who is heterozygous for both traits (TtGg), what would be the genotype of an offspring with black fur and yellow eyes?

In chameleons, green scales (G) are dominant to blue scales (g) and a long tail length (T) is dominant to a short tail length (t). If a chameleon who is heterozygous for both traits (GgTt) mates with another chameleon who is heterozygous (GgTt) for both traits, what is the expected phenotypic ratio of the offspring?

9 Green Scales and Long Tail : 3 Green Scales and Short Tail : 3 Blue Scales and Long Tail : 1 Blue Scales and Short Tail

Mice have two unlinked allele pairs that affect fur color. The table shows how allele pairs affect fur color. The term "agouti" describes fur with pigmentation that changes in each hair from the shaft to the tip, giving the fur a banded appearance. Mice with the (aa) allele pair are albino, regardless of their second allele-pair combination.
What is the probability of albinism in the offspring of a cross between two mice with AaBb alleles? AaBb x AaBb
