Answer: Two recessive genes
Explanation: Every trait is controlled by at least a pair of gene, one inherited from the mother and the other inherited from the father. A recessive gene is a gene whose effect is masked by a dominant gene. A recessive gene lacks the ability to express itself in the presence of a dominant gene. For a recessive gene to manifest outwardly, it must occur in a homozygous state that is the individual must inherit two copies of the gene from its parents, one from the mother and one from the father.
