You breed two black dogs. It results in 3 offspring, the first which is black, the second which is brown, and the third which is white. Give two genetic explanations as to what could cause their fur color. Make sure each explanation includes two genes and follows along with the provided data. Also, explain the genotype of each color of dog and a ratio of the F2 phenotypes you would expect to see from a dihybrid cross. After you're finished, pick one of the explanations and create a hypothesis for the function of each gene which would explain the molecular basis of the fur color Finally, for each of the two genes, explain how a specific functional difference between the two alleles leads to a difference in their functions

Question

You breed two black dogs. It results in 3 offspring, the first which is black, the second which is brown, and the third which is white.

Give two genetic explanations as to what could cause their fur color. Make sure each explanation includes two genes and follows along with the provided data. Also, explain the genotype of each color of dog and a ratio of the F2 phenotypes you would expect to see from a dihybrid cross.

After you're finished, pick one of the explanations and create a hypothesis for the function of each gene which would explain the molecular basis of the fur color

Finally, for each of the two genes, explain how a specific functional difference between the two alleles leads to a difference in their functions

Expert Solution

Step 1

Based on monohybrid cross and dihybrid cross in pea plant, mendel proposed laws of inheritance (law of dominance and law of segregation) and law of independent assortment. Both these laws were based on allelic interactions. But, gene interactions also include non allelic interactions such as complementary interactions, duplicate genes, epistasis, etc.
