Which of the following statements is true about linkage disequilibrium? a. New alleles are born into a population in LE with the surrounding loci b. Genetic hitchhiking results from LD between surrounding loci and a locus under strong selection c. Loci in LE in two different populations with different allele frequencies will remain in LE when the two populations completely merge into a single population. d. The greater the selection on a locus, the smaller the haplotype block maintained around it e. D= 0.15 indicates that two loci are in greater LD than D= -0.23
Genetic Variation
Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.
Quantitative Genetics
Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.
