Complete the following discussions:
The Hardy-Weinberg equilibrium states that allele frequencies remain constant across generations unless certain influences are introduced, 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 forensic investigation and paternity testing. This technique is often used by forensic scientists to identify individuals on the basis of their DNA profiles.
- How is DNA profiling performed?
- What are some of the novel uses of DNA profiling, other than those described in your textbook?
Sickle-cell disease is an example of balanced polymorphism as carriers of this disease are protected against malaria.
- Describe an example of balanced polymorphism, other than sickle-cell disease, glucose-6-phosphate dehydrogenase (G6PD) deficiency, phenylketonuria (PKU), prior protein mutation, cystic fibrosis (CF), and Smith-Lemli-Opitz syndrome (SLOS).
