Define dihybrid cross.
Understand the Problem
The question is asking for a definition of a dihybrid cross, which involves genetics and the study of inheritance patterns of two traits simultaneously.
Answer
A dihybrid cross involves a breeding experiment between organisms that differ in two traits controlled by two genes.
A dihybrid cross is a breeding experiment between P-generation (parental generation) organisms that differ in two traits. These traits are controlled by two distinct genes.
Answer for screen readers
A dihybrid cross is a breeding experiment between P-generation (parental generation) organisms that differ in two traits. These traits are controlled by two distinct genes.
More Information
In dihybrid crosses, the parents that are crossed are typically heterozygous for both traits, and the offspring ratio usually involves a phenotypic ratio of 9:3:3:1.
Tips
One common mistake is confusing dihybrid crosses with monohybrid crosses, which involve only one trait.
