Question

Write one difference between dominant and recessive trait.

Hint:

Dominant traits mask the expression of recessive traits in heterozygotes, while recessive traits are only visible when both alleles are recessive.

Answer 1

A dominant trait is one that expresses itself in the phenotype even when only one copy of the allele is present, whereas a recessive trait only expresses itself when both alleles are recessive (i.e., in the homozygous recessive state).
