In some goats, the presence of horns is produced by an autosomal gene that is dominant in males and recessive in females. A horned female is crossed with a hornless male. The F1 offspring are intercrossed to produce the F2. What proportion of the F2 offspring will have horns?

In the following example, 3 independently assorting genes are known to govern coat color in mice. The genotype of few of the coat colors is given below:
Agouti: A-B-C- Black: aa B-C - Albino: -- -- cc
What will be the expected frequency of abino, in progeny from crosses of AaBbCc with albino of the genotype aabbcc?
