Phenotypic Ratios in a Genetic Cross

What are the expected phenotypic ratios in a genetic cross between two organisms?

For example, if you cross two individuals with genotypes Aa and Bb, what phenotypic ratios can be anticipated?

Answer:

In a genetic cross between two organisms with the genotypes Aa and Bb, the expected phenotypic ratios are:

25%: AABB

50%: AaBb

25%: aabb

When two organisms with different genotypes are crossed, the resulting offspring can exhibit various phenotypic ratios based on the laws of genetics. In this particular example, the phenotypic ratios are determined by the combination of alleles from the two parents.

The ratio of 25% AABB, 50% AaBb, and 25% aabb represents the potential outcomes of the genetic cross. This distribution is based on the principles of Mendelian genetics and the assortment of alleles during meiosis.

Each offspring inherits one allele from each parent, leading to the observed phenotypic ratios. Understanding these ratios is essential in predicting the outcomes of genetic crosses and studying inheritance patterns.
