Is there such thing as a heterozygous dominant / recessive? My biology teacher put a question saying to solve a punnet square with a heterozygous dominant parent and a homozygous recessive parent. I don't think it's possible to solve this because I have done my research and still not able to find out if there is such thing as a heterozygous dominant. I think my teacher is tricking me, is there such thing as a heterozygous dominant? Please let me know, thank you!!!!
