noun, plural: paternal-effect genes

A gene from the father's genome in which the phenotype in the zygote is determined from the father's genotype, not from the zygote's.


By paternal-effect, it means that the gene codes for products synthesized from the father and are inherited by and expressed in the early embryo. Examples of partenal-effect genes are pal, K81, snky, and horka.

Also called: paternal gene.

Compare: maternal-effect gene, zygotic-effect gene.
