Which is true about a dominant gene?
It's represented with a capital letter
It can cover up and hide a recessive gene
It is usually expressed in one's phenotype
All of these are true
Mendel bred plants that had green pods with plants that had yellow pods. All of the offspring had green pods. How did this happen?
The yellow pod gene is recessive and was hidden
The green pod gene is recessive and was hidden
The yellow pod gene is dominant and was expressed
Yellow and green pods are equally dominant.
When is a recessive allele shown in someone's phenotype?
