After about 15 minutes of intense exercise, the dogs wobble about, develop a fever and their hind legs collapse. The parents are healthy. What is the mode inheritance? Be specific. (2 pts) b. Use the letters E and e. What is the genotype of both parents? -(1 pt) Save uestion 55 (Mandatory) (3 points) a. What is the probability that two individuals with an autosomal recessive trait, Like albinism, will have a child with the same genotype and phenotype as they have?2pt b. What is the genotype of an individual with albinism? (use letter a for genotype) 1 pt

Explanation / Answer

1a) Autosomal recessive disorder - Exercise-induced collapse (EIC) follows an autosomal recessive disorder pattern in labrador retrievers. In autosomal recessive pattern, when both the parents are carrier for the disorder, 25% of the offspring will show symptoms, 50% of the offsprings will be carrier and 25% of the offspring will be normal.

1b) Since, both parents are carriers, their genotypes will be

Male parent - Ee

Female parent - Ee
