Cerebellar abiotrophy (CA) is a recessive, genetic neurological disease found in the Arabian horse breed. If the incidence of this disease is about 1 in 400 Arabian horses, estimate the frequency of carriers in a population in Hardy-Weinberg equilibrium. The recessive allele is represented by $$c$$ and the normal, wildtype allele is represented by $$C$$. The frequency of genotype $$CC$$ (homozygous normal) is represented by $$\$p^{?}2\$$$. The frequency of genotype $$cc$$ (homozygous CA) is represented by $$\$q^{?}2\$$$. The allelic frequency of $$C$$ is represented by $$\$p\$$$. The allelic frequency of $$c$$ is represented by $$\$q\$$$. To find the frequency of carriers, we must find $$\$2pq\$$$. Using the equations $$\$p^{?}2+2pq+q^{?}2=1\$$$ and $$\$p+q=1\$$$, determine the following: $$x$$ Value of $$\$q^{?}2\$:$$ $$x$$ Value of $$\$q\$:$$ $$x$$ Value of $$\$p\$:0$$ $$\times$$ Carrier Frequency: 0 .
