You're interested in the genetics of earlobe shape on your campus. Free (unattached) earlobes are caused by a dominant allele. The attached earlobe phenotype is caused by a recessive allele
Individuals with free earlobes have either a homozygous genotype or a heterozygous genotype. Assuming that your college campus is a stable population, what calculation would you use to determine the percentage of students who have a heterozygous genotype for earlobe shape? A) Calculate the percentage of people who have free earlobes.
B) Calculate the percentage of people who are homozygous-dominant for free earlobes.
C) Calculate the percentage of people who have attached earlobes.
D) Calculate the percentage of people who carry the recessive allele.
