An allele that produces its characteristic phenotype only when its paired allele is identical.
1We now know that they carried recessive alleles that contributed to various genetic disorders.
2Purpose: The purpose of this study is to describe recessive alleles in strictly dominant genes.
3This heterosis is greatest with intermediate mutation rates, intermediate selection coefficients, low migration rates and recessive alleles.
4Some mutations behave as both dominant and recessive alleles, but an autosomal recessive inheritance pattern is much more common.
