    A gene in cattle controls whether horns develop or not. When cattle without horns are mated together, none of the offspring ever have horns. A male with horns is mated with females without horns. If half of the offspring have horns and half do not, what is the conclusion?

    The answer is a heterozygous

    Can anyone please help me explain why?
    Thanks!

    When cattle without horns are mated together, none of the offspring ever have horns. this means that not having horns is recessive as if it was dominant one of the parents could be heterozygous and some offspring would have horns.if the horned male was homo dominant all kids would have horns as mum is recessive therefore he must heterozygous
