Red is dominant to blue in poison dart frogs. If we cross a Red male with a blue female, is it possible for them to make blue babies? How?
Yes: both parents would have to be heterozygous for the skin color trait, producing blue babies
No: They would only produce red babies every time because it is dominant
Yes: If dad is heterozygous and mom is homozygous recessive, they would have 50 % chance of making blue babies
No: only two blue frogs can make blue babies because it is recessive
