Definitions for "Recessive inheritance"
Expression of a recessive (nondominant) trait, which occurs only if the offspring receives identical recessive alleles from both parents. (44)
A pattern of inheritance of a characteristic (such as blue eye color) or abnormality (such as congenital absence of the vas deferens) in which two abnormal genes or alleles are needed to confer the characteristic or abnormality, in contrast to dominant inheritance, which requires just one abnormal gene. In the case of alleles found on X-chromosomes but not on the smaller Y-chromosomes, a recessive gene will be unopposed (and so will act as a dominant gene) in males, whereas female carriers of the allele will be unaffected except in the extremely unlikely event that they inherit (or gain by mutation) a second abnormal allele; this mode of inheritance is called sex-linked recessive inheritance.
