1

expected frequency of the recessive allele for a population in Hardy-Weinberg equilibrium

q

2

Single-locus genotype consisting of functionally different genes

heterozygote

3

Reference to offspring that are phenotypically identical to parents of the same phenotype, exclusively

Breed true

4

Specific location of a gene on a chromosome

Locus

5

Type of gene action in which the value of the heterozygote is intermediate to the values of the two homozygotes

Incomplete dominance

6

Expected frequency of the dominant allele for a population in Hardy-Weinberg equilibrium

p^2

7

Expected frequency of the dominant allele for a population in Hardy-Weinberg equilibrium

p

8

Type of gene action in which the value of the heterozygote is equal to the value of one of the homozygotes

complete dominance

9

expected frequency of the homozygous recessive genotype for a population in Hardy-Weinberg equilibrium

q^2

10

Type of gene action in which the heterozygote is typically superior to the homozygous genotypes

overdominance

11

Alternative form of a gene

allele

12

single-locus genotype consisting of functionally similar alleles

homozygotes

13

Which type of inheritance involves genes located on the sex chromosomes?

sex-linked

14

Milk production is an example of which type of inheritance

sex-limited

15

baldness in humans is an example of which type of inheritance?

sex-influenced

16

Four forces that change gene frequencies

Mutation Selection (controlled) Genetic Drift Migration (controlled)

17

Assumptions of Hardy-Weinburg and assumptions

Complete dominance -assuming that there is no mutation, selection, migration, random mating, and large populations.

18

A reduction in performance due to increased homozygosity

inbreeding depression

19

system of mating in which hyprid vigor and breed complementarity are generated and maintained

crossbreeding system

20

a breed consisting of two or more component breeds

composite breed

21

a measure of inbreeding in an individual

Fx

22

hybrid vigor resulting from having a crossbred dam

HV^m

23

mating of individuals more closely related than the average of the population

Inbreeding

24

Hybrid vigor resulting from having a crossbred sire

HV^p

25

A measure of level of pedigree relationship

Rxy

26

System of mating in which the relationship between current progeny and an ancestor is maximized while minimizing the inbreeding coefficient

Linebreeding

27

True/False: a 2-breed specific system yields 100% of both HV^I and HV^M

False

28

True/False: A 3-breed specific system does not produce its own replacement females

True

29

True/False: The management difficulty for a 3-breed rotation system is low

False

30

True/False: a 2-breed rotation system can maximize breed complementarity

False
