QUESTION 1
In mice, an allele for brown eyes (B) is dominant over an allele for apricot eyes (b). At an independently assorting locus, an allele for tan coat color (t) is recessive to an allele for black coat color (T). A mouse that is homozygous for brown eyes and black coat is crossed with a mouse having apricot eyes and a tan coat. The resulting F1 mice are crossed to produce the F2.
a. Diagram the cross, including the expected phenotypes of the F2 generation.
b. The F1 mice have many litters with a combined 19 brown/black, 5 brown/tan, 7 apricot/black, and 1 apricot/tan. Does this fit what would be expected? Do not just say yes or no; show how statistically.
