Lab: Mouse Genetics (Two Traits) Answers

The hypothesis would not have been supported by the data if

. . . the genes assort independently.

Notice that the predicted percentages and laboratory percentages are not the same. These differences most likely result from a computation errora strong linkage between the genes✔ expected randomnessan unusual sample.

A cross was performed, and the offspring shown to the right were produced. What is the most likely genotype for the parents?

Select all the offspring phenotypes that could be produced from a BbEE x bbee cross (shown above).

Cross a parent that is homozygous recessive for both traits (bbee) with a dihybrid (BbEe). First, draw a Punnett square in your notes. For each offspring in the Punnett square, determine the phenotype.In other words, what are the fur color and eye color? Finally, use that information to fill in the predicted fraction of each phenotype in the data table below.

. . . the genes are nearby on the same chromosome.
