Dihybrid (Noun)

Meaning

A hybrid produced by parents that differ only at two gene loci that have two alleles each.

Classification

Nouns denoting animals.

Examples

  • The dihybrid ratio is a fundamental concept in Mendelian genetics, describing the expected proportions of different phenotypes in offspring.
  • In a dihybrid cross, the parents differ at two gene loci, each with two alleles, resulting in a complex pattern of inheritance.
  • The dihybrid testcross is a powerful tool for determining the genotype of an individual at two specific loci.
  • By analyzing the phenotypes of the offspring in a dihybrid cross, researchers can infer the genotype of the parents and the interactions between the two genes.
  • The dihybrid ratio of 9:3:3:1 is a classic example of the expected phenotypic proportions in offspring when two genes interact in a specific way.
