Question 8 Listen In Labrador dogs, there are 2 genes that determine coat color. One gene has a recessive allele (e) which, when homozygous, results in a yellow dog regardless of what the genotype of the dog is at the second gene. However, if there is at least one E allele, the phenotype of the dog will depend on a second gene B. Dogs that are EE, or Ee and BB or Bb will be black. Dogs that are EE or Ee and bb will be chocolate. A dog that is Ee, Bb has offspring with a dog that is Ee, bb. What is the chance that they have an offspring which is black? A) 3/4 B) 1/2 C) 3/8 D) O E) 1/4 F) 1/8

This technique uses: O A. two primers outside the deleted region; a long PCR extension segment. O B. one primer within the deleted region and one primer outside the deleted region; a long PCR extension segment O C. one primer within the deleted region and one primer outside the deleted region; a short PCR extension segment O D. two primers outside the deleted region; a short PCR extension segment O E. two primers within the deleted region; a short PCR extension segment
