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 females will have horns?

    Taking; H + = allele for the presence of horns

    H - = allele for hornlessness

    Since H + is recessive in females, the horned female parents must be H+H+. The hornless male is H-H - because the absence of horns is recessive in males. Then their F1 progeny must be all heterozygous H+H-. An intercross of the F1 would produce both male and female progeny in the ration of 1 H+H+, 2 H+H-, and 1 H-H-. Additionally, remembering that H + is recessive in females, we would expect a ratio of 3:1 hornless to horned females.
