Questions and Answers

What is the primary purpose of linkage analysis?

  • To detect loci with small effect size
  • To detect co-segregation of alleles with a marker locus in family data (correct)
  • To identify common alleles in the population
  • To study the variation of a quantitative trait
  • Why are linkage studies powerful in detecting loci with large effect size?

  • They are effective in identifying rare variants
  • They focus on common alleles in the population
  • They have high power to detect alleles with a large effect size (correct)
  • They are designed to detect loci with small effect size
  • What is a limitation of association studies compared to linkage studies?

  • They are not designed for quantitative traits
  • They have low power to detect rare variants with large effect size (correct)
  • They focus on family data
  • They are ineffective in identifying common alleles
