Predicting Genotypic and Phenotypic Outcomes in Non-Mendelian Crosses

In this assignment, you will explore the concepts of incomplete dominance and codominance in genetics. You will use your understanding of statistics and probability to predict the genotypic and phenotypic outcomes of various genetic crosses. Remember, in incomplete dominance, the heterozygous phenotype is a blend of the two homozygous phenotypes, while in codominance, both alleles are expressed equally in the phenotype.

Use the information provided from your notes and in the questions below to answer the following questions about incomplete dominance and codominance.

Explain how incomplete dominance differs from codominance in terms of phenotypic expression (physical traits seen).

If two roan cattle (RW) are crossed, what is the expected genotypic ratio of their offspring?

A plant species shows incomplete dominance for flower color. If a red-flowered plant is crossed with a white-flowered plant, use a Punnett Square to show what the phenotypes of the first generation will be.
