Question

2) A)How does sexual recombination produce variation?

B) What is true about how individuals in populations tend to mate? Why is this important?

C) What does the Hardy-Weinberg theorem describe? • What is true about the allele and genotype frequencies in the next generation for a population in HW equilibrium? • What do p and q stand for? What about p2, 2pq and q2? • If you are given the number of individuals in a population that express a given genotype, can you calculate the genotype and allele frequencies? • Can you determine from genotype frequencies in the next generation if the population was in HW equilibrium?

D) What are the assumptions or conditions of Hardy-Weinberg equilibrium?

Answer:

Sexual reproduction involve formation of gametes from two parents by the process of meiosis. Crossover is an important event during meiosis where homologous chromosomes pair up with each other and exchange different segments of their genetic material to form recombinant chromosomes. This is the basis of variation during sexual recombination.
