Cards

Term
Gene/allelic Frequency
Definition
The relative frequency of a particular allele in a population
Term
Genotypic Frequency
Definition

The relative frequency of a particular one-locus genotype in a population

 

Term
Population Genetics
Definition
The study of factors affecting gene and genotypic frequencies in a population
Term
Fixation
Definition

The point at which a particular allele becomes the only allele at its locus in a population -- the frequency of the allele becomes one

 

 

Term
Allele Frequency
Definition

p+q=1

Usually big letter = p

Usually small letter = q

Term

Genotypic Frequency

 

Definition

p+H+Q=1

how many of certain genotypes are present 

Term
Hardy-Weinberg Equilibrium
Definition

p2 + 2pq + q= 1

A state of constant gene and genotypic frequencies occuring in a population in the absence of forces that change those frequencies

 

Term
Quantitative genetics
Definition

the branch of genetics concerned with influences on, measurement of, relationships among, genetic prediction for, and rate of change in traits that are or can be treated as quantitative (anything that can be measured)

 

Term
Basic genetic model for quantitative traits
Definition

P=µ+G+E

 

Term
Phenotypic Value (P)
Definition
A measure of performance for a trait in an individual
Term
Population mean (µ)
Definition
The average phenotypic value of all individuals in a population
Term
Genotypic Value (G)
Definition
the oeffect of an individuals genes on its performance for a trait
Term
Environmental Effect (E)
Definition
the effect that external factors have on an animal performance
Term
Breeding Value (BV)
Definition
value of an induvidual as a parent (genetic)
Term
Independent Gene Effect
Definition
the effect of a gene independent of the effect of the other gene at the same lovus and the effects of genes at other loci
