In humans, albinism (unpigmented skin, hair, and eyes) is due to an enzymatic deficiency, and it is an autosomal recessive trait. Suppose that in a small country of one million people (“Generation 1”), there are 500 aa albinos and 9000 Aa heterozygous carriers. What is the probability that a child will be albino if: Both parents are members of Generation 2, and one parent is albino and the other is non-albino.

For two species A and B in competition, the carrying capacities, competition coefficients, per capita growth rate and population size are

KA = 1000          KB = 1200        α= .5    r A= .3    N1= 500         N2= 200
