what would happen if father and mother both have the dominant trait on one single characteristics ? like colour of eye
If mother & father both have dominant eye colour, their expected genotype could be- either homozygous or heterozygous. If homozygous, all offspring would have the same eye colour like parent but if both the parents are heterozygous, then one of the offspring would have recessive eye colour & rest would have similar eye colour like their parents.
