#Unit 8. Inheritance Biology

In some sheep, the presence of beard is produced by an autosomal allele that is dominant in males and recessive in females. A beard female is crossed with a homozygous beardless male. One of the resulting F1 females is crossed with a beardless male. What proportion of the male and female progeny from this cross will have beard in F2 generation?
