ANSC 4395 Final Exam Rated A+ 2024Accuracy - ANSWER-______________ is higher for higher levels of heritability.
Accuracy - ANSWER-_______________ always increases as n increases although less
with each additional sib.
Accuracy - ANSWER-_______________ is fairly high for individual records if the
heritability is at least moderate.
Accuracy - ANSWER-_______________ is never high when pedigree info is used.
Accuracy - ANSWER-The confidence we have in an estimate of breeding value is
measured by a statistic.
Additive Effect - ANSWER-Occur when two or more genes source a single contribution
to the final phenotype.
Additive effects
Dominance effects
Epistatic effects - ANSWER-Genetic effects can be divided into
Best additive genotype
Best dominance genotype
Best epistatic genotype
Best permanent environment genotype
Best temporary environment genotype - ANSWER-The best animals may have:
Breeding value - ANSWER-Genetic merit can also be called
Constant - ANSWER-Gene action at one locus may not be _______________.
Dominance Effect - ANSWER-Phenomenon of one variant (allele) of a gene on a
chromosome masking or overriding the effect of a different variant of the same gene on
the other copy of the chromosome.
Epistasis - ANSWER-Interaction among genes at multiple loci.
Epistasis - ANSWER-May have interaction between 2, 3, or more loci.
Epistatic Effect - ANSWER-The phenomenon where the effects of one gene are
modified by one or several other genes at different loci.
Estimated Breeding Value - ANSWER-A prediction of a breeding value.
, Favorable - ANSWER-________________ genetic correlations might allow us to make
selections more efficiently.
From herd to herd
Within a herd if management changes - ANSWER-Heritability is not constant, is varies...
Full sibs - ANSWER-1/2 genes in common
Generation Interval - ANSWER-The length of time it takes to replace the members of
one generation in a herd.
Genetic - ANSWER-______________ correlation only evaluates the common genetic
contributions.
Genetic Correlation - ANSWER-Association between genetic merit for two traits.
h^2 - ANSWER-Heritability is symbolized as
Half - ANSWER-An individual receives _______ of its genetic makeup from each
parent.
Half sibs - ANSWER-1/4 genes in common
Heritability - ANSWER-Makes it much easier to show selection progress for growth and
carcass traits than for reproductive traits.
Heritability - ANSWER-Provides information about differences between individuals and
the nature of the variation within a population.
Heritability - ANSWER-The most important single concept in animal breeding.
Heritability - ANSWER-The proportion of the phenotypic variation which is due to
additive gene effects.
Heterozygote - ANSWER-__________________ is exactly half way between the
homozygotes.
Identical - ANSWER-The activity at any one pair of genes is ______________ to the
types of gene action discussed in simply-inherited traits.
Independent Culling Levels - ANSWER-A minimum level of performance is established
for each trait.
Independent Culling Levels - ANSWER-All important traits are considered together.
