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.
hope this !
the two substances are rock (molten and solid) and metal (solid + liquid).
layers of the earth from the outside in:
1. crust. hard rock/dirt/ground. shell
2. mantle. melted rock and stuff. egg white
3. core. outer core - liquid. inner core- solid. nickle and iron. yolk
b. water is a polar molecule that acts as a universal solvent.
