The cattle breeding program wants to maximize their chances of producing polled (hornless) calves. They know the polled trait is dominant. Which breeding strategy would give them the highest probability of polled offspring?
Question 4 options:
Cross two heterozygous polled animals for 75% polled offspring
Cross a heterozygous polled animal with a horned animal for 50% polled offspring
Cross two horned animals since recessive traits are more predictable
Cross two homozygous polled animals for 100% polled offspring
