Lecture 7 - Analysis Of Genetic Variation In Population

Question 1

Genetic Constitution Definition

Answer 1

Pool of genes/alleles at any one time
Can be referred to as allele frequency

Question 2

Genetic Structure Definition

Answer 2

The way alleles are distributed and combined within populations

Question 3

Gene Flow Definition

Answer 3

Movement of individuals and associated genetic material between populations

Question 4

Genetic Drift Definition

Answer 4

Change of gene frequency in a population due to chance

Question 5

Founder Effect Defintion

Answer 5

Reduced genetic diversity due to small founding population

Question 6

Nei’s GST definition

Answer 6

Co-efficient of Gene Differentiation
Used to compare sub-populations
High GST = high differentiation (=inbreeding)

Question 7

Genetic Distance Definition

Answer 7

Degree of Relationship by descent between individuals/populations

Question 8

Nei’s D Definition

Answer 8

Measure of Genetic Distance
Probability that a randomly chosen allele of each population will be identical, relative to the probability that 2 randomly chosen alleles from the same population will be identical

Question 9

Distance Matrix Definition

Answer 9

Matrix of relations between different populations
Can be done for multiple populations
