give an example of a dominant allele and a recessive allele?

Answer 1

like dark eyes are dominant to light eyes. Cleft (butt) chin is dominant to flat (normal) chin. If your mother is heterozygous for Brown eyes and your father is homozygous for blue eyes. the possible genotypes of their offspring would be fifty percent heterozygoes brown eyes (Bb) and fifty percent homozygoes blue eyes (bb).

Answer 2

So you are crossing a homozygous bronze, hairy bird (RRhh) with a homozygous red, normal feathered bird (rrHH). In a punnet square cross you will end up with all offspring being RrHh genytypes which translates to a heterozygous bronze, normal feathered phenotype. Or is there something else I am missing?

Answer 3

Dominant would be like if you were right handed (more people are that way) Recessive is like if you were left handed (less people are that way)

Answer 4

Here is something useful
