Monohybrid | definition of monohybrid by Medical dictionary
Also found in: Dictionary
The hybrid of parents that differ at only one gene locus, for which each parent is homozygous with a different allele.
Etymology: Gk, monos + L, hybrida, mixed offspring
pertaining to or describing an individual, organism, or strain that is heterozygous for only one specific trait or that is heterozygous for the single trait or gene locus under consideration.
monohybrid (mŏn″ō-hī′brĭd) [″ + L. hybrida, mongrel]
Offspring of a cross between parents differing in a single genetic characteristic.
monohybrid an organism that carries two different ALLELES of one gene. For example character A (controlled by alleles A 1 and A2) would produce a monohybrid GENOTYPE of A 1A 2, i.e. a HETEROZYGOTE.
A monohybrid cross is one in which two parents are crossed to produce monohybrids that are then mated, or a single monohybrid plant is self-fertilized (see SELF-FERTILIZATION). Mendel formulated his law of SEGREGATION from the results of a monohybrid cross involving single characters in the pea plant.
