Breeding Final Flashcards
expected frequency of the recessive allele for a population in Hardy-Weinberg equilibrium
q
Single-locus genotype consisting of functionally different genes
heterozygote
Reference to offspring that are phenotypically identical to parents of the same phenotype, exclusively
Breed true
Specific location of a gene on a chromosome
Locus
Type of gene action in which the value of the heterozygote is intermediate to the values of the two homozygotes
Incomplete dominance
Expected frequency of the dominant allele for a population in Hardy-Weinberg equilibrium
p^2
Expected frequency of the dominant allele for a population in Hardy-Weinberg equilibrium
p
Type of gene action in which the value of the heterozygote is equal to the value of one of the homozygotes
complete dominance
expected frequency of the homozygous recessive genotype for a population in Hardy-Weinberg equilibrium
q^2
Type of gene action in which the heterozygote is typically superior to the homozygous genotypes
overdominance
Alternative form of a gene
allele
single-locus genotype consisting of functionally similar alleles
homozygotes
Which type of inheritance involves genes located on the sex chromosomes?
sex-linked
Milk production is an example of which type of inheritance
sex-limited
baldness in humans is an example of which type of inheritance?
sex-influenced
Four forces that change gene frequencies
Mutation Selection (controlled) Genetic Drift Migration (controlled)
Assumptions of Hardy-Weinburg and assumptions
Complete dominance -assuming that there is no mutation, selection, migration, random mating, and large populations.
A reduction in performance due to increased homozygosity
inbreeding depression
system of mating in which hyprid vigor and breed complementarity are generated and maintained
crossbreeding system
a breed consisting of two or more component breeds
composite breed
a measure of inbreeding in an individual
Fx
hybrid vigor resulting from having a crossbred dam
HV^m
mating of individuals more closely related than the average of the population
Inbreeding
Hybrid vigor resulting from having a crossbred sire
HV^p
