Human hair color is controlled by one gene with four alleles (with some incomplete dominance):
HBr = brown
HBd = blonde
hR = red
hbk = black
The possible genotypes and phenotypes:
HBd HBd or HBd hbk = blonde
HBr HBr or HBr hbk = brown
HBd HBr = mousy brown
HBr hR = auburn
HBd hR = strawberry blonde
hRhR or hRhbk = red
hbk hbk = black

If someone with strawberry blonde hair has a child with someone who has mousy blonde hair, what are the genotype and phenotype probabilities of their children?

If someone with brown hair (with a red hair parent) has a child with someone who has blonde hair (who also has a parent with red hair), what are the genotype and phenotype probabilities of their children?
