Why are loss-of-function mutations frequently recessive when heterozygous with a wild-type allele? The loss-of-function allele often produces a new phenotype that is different from wild type. The wild-type protein function is often sufficient to compensate for the reduced-function protein. The loss-of-function allele is often silenced, and only the wild-type allele is expressed. The wild-type allele is often expressed at higher levels compared to the loss-of-function allele.

Explain why most loss-of-function alleles (hypomorphic or amorphic) are recessive to wild-type alleles, but some are incompletely dominant or dominant.
