Wild-type mice have brown fur. You have two strains of pure breeding mutant mice, both of which have white fur. When you cross the two strains with each other, all of the progeny have wild-type brown fur. What does this genetic complementation tell you?.

Respuesta :

You cross the two strains with each other, all of the progeny have wild-type brown fur. This is more than one gene is involved in determining the coat color phenotype genetic complementation tell you.

  • In the laboratory mouse, over 80 genes have been found to influence coat colour, and more than 25% of them have undergone molecular characterization.
  • The MC1R gene alleles that mice inherit have an impact on the colour of their fur.
  • The fur colour of mice with two copies of allele 1 is the lightest, that of mice with two copies of allele 2 is the darkest, and that of mice with heterozygotes is in the middle.
  • Our bodies can alter the types or quantities of hormones we produce in response to changes in age, nutrition, climate, sun exposure, and a number of other factors. Over the course of a lifetime, the genes that produce melanin may turn on or off, changing the colour of your hair. Some animals have a twice-yearly hair colour shift.
