Answer Parts A-D (A,B,C,D)

**Genetics:** A geneticist is studying two genes. Each gene can be either dominant or recessive. A sample of 100 individuals is categorized as follows. Write your answer as a fraction or a decimal, rounded to four decimal places.

|             | Gene 2 Dominant | Gene 2 Recessive |
|-------------|------------------|------------------|
| **Gene 1 Dominant**   | 59               | 22               |
| **Gene 1 Recessive** | 12               | 7                |

**(a)** What is the probability that in a randomly sampled individual, gene 1 is recessive?

**(b)** What is the probability that in a randomly sampled individual, gene 2 is recessive?

**(c)** Given that gene 1 is recessive, what is the probability that gene 2 is recessive?

**(d)** Two genes are said to be in linkage equilibrium if the event that gene 1 is recessive is independent of the event that gene 2 is recessive. Are these genes in linkage equilibrium?
