Hardy-Weinburg questions???

1) The deleterious recessive allele exists at a proportion of 0.01. In an offspring with randomly chosen parents, what is the probability that the offpsring will be homozygous for the deleterious recessive allele [q]?

2) A Generation of Indiviuals in a Population: A1A1   A1A1   A1A2   A1A2 A2A2

So the allels present in the generation are : A1 A1 A1 A1 A1 A2  A1 A2  A2  A2  A2

a. What is the probability that Allele A1 eventually becomes fixed in the population?

b. What is the probability that Allele A1 eventually disappears from the population?

c. What is the probability that Allele A2 eventually becomes fixed in the population?

d. What is the probability that Allele A2 eventually disappears from the population?

A1 = p

A2 = q

Please help me with the numbers!!!!

Explanation / Answer

The probability that A1 is xed is equal to its initial frequency, p0, and the probability
that A2 is xed is equal to its initial frequency, q0.
Both of these properties are true in general for any nite population and any number of
alleles.
1. Genetic drift will eventually lead to loss of all alleles in the population except one

The probability that any allele will eventually become xed in the population is equal
to its current frequency
