The Hardy-Weinberg equilibrium states that allele frequenciesremain constant across generations unless certain influences areintroduced, such as nonrandom matings or mutations.
Describe the Hardy-Weinberg principle.
Are there influences that deviate from the principle? If so,what are they? If no, why?
Deoxyribonucleic acid (DNA) profiling is a tool used in forensicinvestigation and paternity testing. This technique is often usedby forensic scientists to identify individuals on the basis oftheir DNA profiles.
How is DNA profiling performed?
What are some of the novel uses of DNA profiling, other thanthose described in your textbook?
Sickle-cell disease is an example of balanced polymorphism ascarriers of this disease are protected against malaria.
Describe an example of balancedpolymorphism, other than sickle-cell disease, glucose-6-phosphatedehydrogenase (G6PD) deficiency, phenylketonuria (PKU), priorprotein mutation, cystic fibrosis (CF), and Smith-Lemli-Opitzsyndrome (SLOS).
Genetic ancestry testing isbecoming popular as more and more people are trying to trace theirancestry. Two different types of tests are generally offered,mitochondrial DNA, which traces maternal lineages, and Y chromosometesting, which traces paternal lineages.
Does genetic ancestry testingprovide a complete picture of a person's heritage? If so, how? Ifnot, why not?
