Dihybrid Cross (Noun)
Meaning
Hybridization using two traits with two alleles each.
Classification
Nouns denoting acts or actions.
Examples
- The dihybrid cross involves crossing two parents that are heterozygous for two different genes, resulting in a unique ratio of genotypes and phenotypes in the offspring.
- A dihybrid cross is typically represented as AaBb x AaBb, where A and a represent the alleles of one gene, and B and b represent the alleles of the other gene.
- Gregor Mendel first described the concept of a dihybrid cross in his experiments with pea plants, demonstrating the principle of independent assortment of alleles.
- The Punnett square is a useful tool for predicting the outcomes of a dihybrid cross, allowing researchers to determine the probability of different genotypes and phenotypes.
- By analyzing the results of a dihybrid cross, scientists can determine whether two genes are linked or segregate independently, providing insights into the genetic basis of traits.
