MGB 3060 FINAL QUESTIONS WITH DETAILED VERIFIED
ANSWERS (100% CORRECT ANSWERS) /ALREADY
GRADED A+
Quiz: 1) Individuals may have several common?
2) Each one contributes a separate probability that?
Ans: 1) ancestors
2) the allele in X are copies of the same ancestral alleles
Quiz: 1) Describe the elements of how we often need to know how
much two individuals are related
2) Relationships form the basis of?
Ans: 1) -relatives have alleles in common
-relatives tend to be more similar (than two random individuals from a
population)
-information on relatives can be used to gain information on individuals
(example: heights of brothers and sisters)
2) a lot of quantitative genetic studies
Quiz: 1) What does phenotype depend on?
2) What we observe is a function of?
Ans: 1) the genotype and the environment
2) genetics and environment
,Quiz: 1) Dominance and interaction genetic effects as well as
permanent environment are specific to?
2) Our goal as geneticists is to determine?
Ans: 1) the animal and are not passed on, so we often ignore it all
2) A as accurately as possible
Quiz: 1) What is the additive genetic component?
2) What is the dominant genetic component?
3) What is the interaction genetic component?
Ans: 1) a measure of the sum of effects of individual alleles ('genes working
together')
2) a measure of the combined dominance effects of individual loci
3) a measure of the combined interactions between loci (epistasis)
Quiz: Only the additive part is passed on in?
Ans: gametes
Quiz: 1) What is broad sense heritability?
2) What is narrow sense heritability?
Ans: 1) the proportion of total variance that is genetic
2) the proportion of total variance that is additive genetic and 1/2 is
transmitted from parent to offspring
Quiz: What are the two methods of estimating heritability?
Ans: -regression of offspring (y) on parent (x)
Examstudy - Stuvia US
, -ANOVA-phenotypes on specific relatives
Quiz: Why is offspring-midparent regression preferred over offspring-
parent regression?
Ans: because it includes more information
Quiz: Why are we interested in heritability?
Ans: it measures the proportion of total variation that is additive genetic
variation
-indicates degree of genetic resemblance between relatives and
generations
-helps define how much genetic change would result from selection
Quiz: 1) How can we increase response to selection?
2) How can increasing heritability increase response to selection?
Ans: 1) -increase selection differential (fewer individuals-watch out for
inbreeding)
-increase heritability
2) -measure phenotype more precisely, reduce variation of the environment
-little else we can do statistically
Quiz: What if we select a proportion of the population? How do we
figure out the selection differential?
Ans: use a standard normal distribution to find S for all possible situations
