Question
imagine that you finally solved the mystery of the color pattern of zebras. One gene defines the color of the fur, with two alleles for two colors: black (B) and white (b). Both alleles are co-dominant.
Another gene regulates the expression of the color through epistasis. You name the two alleles for this regulator gene G and g. The dominant allele G is necessary for the fur color (white is considered a color) to be produced. The recessive g allele does not allow fur color expression. Zebra with no fur color expression appear green.
You breed two double heterozygous zebras.
- A)What do these double heterozygotes look like?______________________
- B) Fill the Punnett square and provide the predicted proportion of zebras of different colors from that cross....
The colors obtained are the following (include expected ratio or percentage):
C)Naturally, there are no green zebras. Propose a genetic explanation for this lack of green zebras?
