Question

Pedigrees and Sex Linkage 6of6 The pedigree from Part B is shown below. Condition A Female Il-4 is pregnant via male lIl-5. The owner of this breeding pair wants to know the probabilities of several possible outcomes for their offspring (IV-3). If you need help with how to approach calculating these probabilities, use the Hint. Answer each question by dragging the correct label to the appropriate location. Labels can be used once, more than once, or not at all.

What is the probability that 1.3 will have both conditions? 4. What is the probability that IV-3 will have neither condition? s. What is the probability that V-3 will have at least one of the two conditions? I8 9/64 40218 55/64 2451248

Explanation / Answer

1) The probablity that IV-3 will have condition A is:

2/3 X 1/2 X 1/2 X 2/3 X 1/2 X 1/2 = 1/36

2) The probablity that IV-3 will have condition B is:

1/2 X 1/2 X 1/2 = 1/8

3) The probablity that IV-3 will have both conditions is:

1/36 X 1/8 = 1/228

4) The probablity that IV-3 will have neithe condition is:

(1-1/36) - (1-1/8) = 35/36 X 7/8 = 245/288

5) The probablity that IV-3 will have at least one of the two conditions is:

1-245/288 = 43/288
