In a species of goat, white and brown are codominant. One parent is solid white and the other parent is solid brown. What is the predicted phenotype of their offspring? Sketch a Punnett square to find the answer.

A genotype where only recessive alleles

were passed on from both parents for one trait

bb aa tt ll

A genotype where only dominant alleles were passed on

from both parents for one trait

The instructions of this allele are covered up by the other allele in a homologous pair. Symbolized by a small letter.

The instruction of one allele covers up the instruction

of the other allele in a homologous pair. Symbolized by a capital letter.
