Pseudodominance

Pseudodominance (pronunciation: soo-doh-doh-min-ance) is a phenomenon in genetics where a recessive allele appears to be dominant due to the deletion or absence of the dominant allele.

Etymology

The term "Pseudodominance" is derived from the Greek word "pseudo", meaning false, and the Latin word "dominant", meaning ruling or governing.

Definition

Pseudodominance occurs when a recessive allele appears to be dominant because the dominant allele is absent or deleted. This can occur in cases of chromosome deletion or when an individual is homozygous for a recessive allele.
