Multiple Choice

If a trait is controlled by 5 polygenes, how many phenotypic categories will be observed in the F2 generation?

Previous problemNext problem

Verified step by step guidance

Understand that polygenic inheritance involves multiple genes contributing to a single trait, and each gene can have multiple alleles.

Recognize that the number of phenotypic categories in polygenic inheritance can be calculated using the formula: number of categories = number of polygenes + 1.

Identify that the problem states there are 5 polygenes controlling the trait.

Apply the formula: number of categories = 5 polygenes + 1.

Conclude that the number of phenotypic categories observed in the F2 generation will be 6.
