Genetics and Health Week 8

Question 1

Define Reproductive Fitness

Answer 1

An individual’s ability to pass their genes to subsequent individuals

Question 2

What are the five conditions of Hardy-Weinberg?

Building Relationshing but NO MMS

Answer 2

1) Large Breeding Population
2) Random Mating
3) No Mutation of the alleles
4) No Migration change
5) No selection

Question 3

What are the four exceptions to the Hardy-Weinberg?

PUMP

Answer 3

1) Non-random mating
2) Unequal Survival
3) Population Subdivision
4) Migration

Question 4

Non-random Mating

A) Assortative Mating
B) Consanguineous Mating

Answer 4

A) Assortative Mating: Phenotypic Traits are major

B) Consanguineous Mating: Related individuals

Question 5

Define Heterozygote Advantage

Answer 5

Heterozygotes have the highest reproductive fitness and they will persist in the population

Question 6

Define The Founder Effect

Answer 6

The small sub-population becomes isolated, producing a genetic drift, decreasing genetic diversity

Question 7

Define The Bottleneck Effect

Answer 7

Natural events or disasters or dangerous events that sharply reduce the population, genetic diversity will increase only with random mating
