The link between SCT and increased risk of death has been documented. Is that not enough to warrant testing, as long as a link exists? Couldn't one argue that it would instead be neglectful to NOT test for this trait since we do know that such a link exists?
In humans, Rh-positive individuals have the Rh antigen on their red blood cells, while Rh-negative individuals do not. If the Rh-positive phenotype is produced by a dominant gene (A), and the Rh-negative phenotype is due to its recessive allele (a), what is the frequency of the Rh-positive allele if 84% of a population is Rh-positive?
Using the observed counts for each genotype, how do you find the expected values with those numbers and the frequencies?
