Epistasis Read the scenario and answer the questions below. Epistasis is a term scientists use to describe how one gene's activity can "mask" or hide another gene's activity. In rats, there are more than one gene that determine the rat's coat color. Allele Notation Key: B = black hair b = brown hair N = pigmented n albino %3D %3D %3D One gene (B) controls the color: black or brown. The B allele causes black hair; bb individuals have brown hair. Write a fraction for the offspring will have each trait: Another gene (N) controls the presence of any pigment at al. The N allele allows individuals to have color in their fur, nn individuals are albino and look pale white with pink eyes. 7. bb genotype (disregarding the albinism gene): 8. BB or Bb genotype (disregarding the albinism gene): So individuals who have twonalleles will not show either black or brown coloring. The N gene "masks" the B gene. Scientists would say that the N gene is epistatic to the B gene. Fill out the information below and answer the questions on the right. Use whatever method you would like to solve this problem; use the space below for your work. 9 nn genotype: 10. NN or Nn genotype: I. albino: heterozygous black female, heterozygous for albinism brown male, heterozygous for albinism 12. brown hair: 13. black hair: L Phenotype: 4. Phenotype: 2. Genotype: 5.
