Red-green colorblindness in an X-linked trait. The normal allele is dominant and the allele that causes color blindness is recessive. Approximately 1 in 12 males of N. European ancestry are red-green color blind. What frequency of females of N. European ancestry are red-green color blind? 

The ratio of genetic variance to overall phenotypic variance is called ____________.

Sickle cell anemia shows autosomal recessive inheritance. In individuals who can trace ancestry to regions where malaria is endemic, the incidence of sickle cell anemia is approximately 1 in 500. In 50, 000 individuals who can trace ancestry to a malaria endemic region, approximately how many individuals are heterozygous? (I used 5 decimal places in numbers in my calculation to generate the answer). p2 + 2pq + q2 = 1
