Question

Problem 5 (8 points) A geneticist is studying two genes. Each gene can be Dominant (Gene 2) Recessive (Geve 2) Dominant (Gene 1) Recessive (Gene 1) a. What is the probability that Gene 1 is dominant? What is the b. What is the probability that Gene 1 is c. Given the Gene d. Given the Gene 1 is recessive, what is the probability that Geme 2 is e. These genes are said to 24 probability that Gene 2 recessive? What is the probability that Gene 2 is dominant? is recessive? 2 is dominant, what is the probability that Gene 1 is dominant? recessive? be in linkage equilibrium if the evest that Gene 1 is dominant is independert a that Gene 2 is dominant. Are these genes in linlange equilibriums

Explanation / Answer

a.) Probability that Gene 1 is dominant = 20/100. Probability that Gene 2 is dominant = 30/100

b) Probability that Gene 1 is recessive = 80/100. Probability that Gene 2 is recessive = 70/100

C) required probability = 6/30 ( look in column 1)

D) required probability = 56/80 ( look in the row 2)

E) probability(gene 1 dominant and gene 2 dominant) = 6/100

Which is equal to probability (gene 1 dominant) * probability (gene 2 dominant). Thus, they are independent and thus in linkage equilibrium.
