Question 40

In a certain population of Red Deer, one in 10,000 births results in a fawn with chondrodysplasia (a form of dwarfism). Chondrodysplasia is a recessive condition caused by a mutation in a gene regulating skeletal development.

According to the Hardy-Weinberg principle, the following equations can be used to estimate allele and genotype frequencies within a population:

p2+2pq+q2=1 p^2 + 2pq + q^2 = 1 p2+2pq+q2=1 p+q=1 p + q = 1 p+q=1

Use the Hardy-Weinberg equations to calculate the percentage of Red Deer in this population that are heterozygous (carriers) for the chondrodysplasia allele. Give your answer to one significant figure. Show your working.
