CROSSOVER EXPERIMENT
DNA from homolog ADNA from homolog BColor traces DNA origin, not dominance
Exchange chromosome segments. Follow the alleles into four gametes.
Discover how crossing over reshuffles what was already there.
This is an imaginary two-gene model based on your chromosome sketches. Real human eye and hair color involve many genes. Gametes carry alleles; they do not have eye or hair colors. Crossing over: NHGRI · Human eye color · Human hair color
