Question

Sickle cell disease (SCD) is caused by a recessive version of the hemoglobin gene. In the US, SCD occurs in about 0.2% of the newborn babies. In some African countries, 4% of the newborn babies have sickle cell. Out of a random sample of 10,000 newborn babies in the US, how many would you expect to be homozygous for the normal, dominant hemoglobin genotype assuming Hardy Weinberg equilibrium?

Step 1

First, we need to determine the frequency of the normal, dominant hemoglobin genotype in the US population. Since SCD occurs in about 0.2% of newborn babies, we can assume that the frequency of the recessive sickle cell allele is q = 0.002. Show more…
