Question 11 (1 point) Save

As the degree of relatedness within a population increases, the level of inbreeding in that population also increases. As relatedness and inbreeding go up, individuals become more similar genetically and therefore genetic variability goes down. How would an increase in inbreeding and relatedness affect the variability we would see due to over-dominance?

1) The variability would be unaffected because the proportion of heterozygous individuals would decrease and those individuals have the largest expression of phenotype.



2) The variability would decrease because the proportion of heterozygous individuals would decrease and those individuals have the largest expression of phenotype.

3) The variability would increase because the proportion of heterozygous individuals would decrease and those individuals have the largest expression of phenotype.

As the degree of relatedness within a population increases, the level of inbreeding in that population also increases. As relatedness and inbreeding go up, individuals become more similar genetically and therefore genetic variability goes down. How would an increase in inbreeding and relatedness affect the variability we would see due to incomplete dominance?

1) The variability would be unaffected because the proportion of heterozygous individuals would decrease and those individuals have a phenotype closer to one of the homozygotes.

2) The variability would decrease somewhat because the proportion of heterozygous individuals would decrease and those individuals have a phenotype closer to one of the homozygotes.

3) The variability would increase somewhat because the proportion of heterozygous individuals would decrease and those individuals have a phenotype closer to one of the homozygotes.

As the degree of relatedness within a population increases, the level of inbreeding in that population also increases. As relatedness and inbreeding go up, individuals become more similar genetically and therefore genetic variability goes down. How would an increase in inbreeding and relatedness affect the variability we would see due to co-dominance?

1) The variability would increase somewhat because the proportion of heterozygous individuals would decrease and those individuals have a phenotype between the homozygotes.

2) The variability would be largely unaffected because the proportion of heterozygous individuals would decrease and those individuals have a phenotype between the homozygotes.

3) The variability would decrease somewhat because the proportion of heterozygous individuals would decrease and those individuals have a phenotype between the homozygotes.
Question 14 (1 point) Save

As the degree of relatedness within a population increases, the level of inbreeding in that population also increases. As relatedness and inbreeding go up, individuals become more similar genetically and therefore genetic variability goes down. How would an increase in inbreeding and relatedness affect the variability we would see due to epistasis?

1) The variability would decrease somewhat because the proportion of heterozygous individuals would decrease and the epistatic interactions would decrease with it.

2) The variability would increase somewhat because the proportion of heterozygous individuals would decrease and the epistatic interactions would increase with it.

3) The variability would increase or decrease somewhat or even stay the same because the proportion of heterozygous individuals would decrease but the epistatic interactions could occur amongst any combination of genotypes.
Question 15 (1 point) Save

As the degree of relatedness within a population increases, the level of inbreeding in that population also increases. As relatedness and inbreeding go up, individuals become more similar genetically and therefore genetic variability goes down. How would an increase in inbreeding and relatedness affect the variability we would see due to pleiotropy?

1) The variability would increase or decrease somewhat or even stay the same because the proportion of heterozygous individuals would decrease but the pleiotropic interactions could occur amongst any combination of phenotypes.

2) The variability would increase somewhat because the proportion of heterozygous individuals would decrease and the pleiotropic interactions would increase with it.

3) The variability would decrease somewhat because the proportion of heterozygous individuals would decrease and the pleiotropic interactions would decrease with it.
