In pigeons, the allele for normal feathers (F) is dominant to the allele for frizzy feathers (f). If a purebred, normal-feathered bird is crossed with a frizzy feathered bird, what percentage of the offspring will possess normal feathers?
100% because if you do a punnett square there is always a dominant alle so they are all Ff, when there is a dominant alle present the offspring gets the dominant trait.
