a black fur mouse is thought to have Bb phenotype. It is mated with a while fur(bb). All their 37 offspring are balck. Is the parent black fur mouse hybrid or homozygou?explain
I think it's homozygous, because when you cross a homozygous dominant (black) with a homozygous recessive (white) in a punnett square, then all their offspring will be heterozygous (hybrid) and they will be black. :)
