... For example, the probability of producing 2 blue gametes for individual A is 1/2 x1/2 = 1/4. Similarly, the probability of producing 2 red gametes is also 1/4, but the probability of producing a red and a blue gamete is 1/2 (1/4 + 1/4). FA is the inbreeding coefficient of the individual producing th ...
