4) The female dog has black fur. The male dog has black fur. Figure out the phenotypes and genotypes of their possible puppies by using a Punnett Square.
% of possible Genotypes:
FF: 0%
Ff: 100%
ff: 0%
% of possible Phenotypes:
Black fur: 100%
Grey fur: 0%
5) The female dog is heterozygous. The male dog is heterozygous. Figure out the phenotypes and genotypes of their possible puppies by using a Punnett Square.
% of possible Genotypes:
FF: 25%
Ff: 50%
ff: 25%
% of possible Phenotypes:
Black fur: 75%
Grey fur: 25%
6) In fruit flies, red eyes are dominant (E). White eyes are recessive (e). If the female fly has white eyes and the male fly has homozygous dominant red eyes, what are the possible phenotypes and genotypes of their offspring?
Genotypes:
EE: 0%
Ee: 100%
ee: 0%
Phenotypes:
Red Eyes: 100%
White Eyes: 0%
