The answers

Question 1(a) · 141 words written

1.a) Hardy-Weinberg Law

Opening · a definition

Hardy-weinberg law or law of equilibrium talks about an ideal population group on which no natural selection is acting upon and it maintains its genetic pool in next generation.

It talks about ideal human population which follow mendelian population principles.

pre-requisite

Body · points and prose

  • random mating
  • large population
  • all traits can equally manifest
  • no selection, migration or mutation

principle -> number of genotype and associated allele contribution will remain same from one to next generation.

Significance -> determine heterozygosity frequency -> estimate multiple allele frequency check if population is evolving or in equilibrium

Factor affecting equilibrium in population (1) selection

  • selective
  • direction
  • balanced
  • disruptive (2) Mutation (3) Migration and inbreeding (4) Genetic imprinting (5) Genetic drift.

Close · a summary

Hardy weinberg principle is an ideal population to determine the change in population and its genotype over time.
