In a breed of mice gray fur is dominant to white fur what letters will be used to represent the gray and white alleles

yes? sounds right, but you didn’t ask a question.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
