Question

For each population description, identify which Hardy-Weinberg assumption is violated?
1. A small and isolated population of seals living in a stable environment with no genetic mutations.
2. A large population of fish where females mate with males based on size.
3. A population of birds with no genetic mutations that often mate with members of neighboring bird populations.
4. A large population of squirrels in a stable environment in which mating is random and the mutation rate is very low but constant.
5. A population of spiders living in an environment that strongly favors larger individuals.

Answer 1

Answer:

4. A large and isolated population of squirrels in a relatively stable environment in which no genetic mutations are occurring and mating between males and females is random.

Explanation:

1. A small and isolated population of seals living in a stable environment with no genetic mutations.❌

1. false

Hardy-Weinberg assumption is not violated for a small population as seen in this case.

2. A large population of fish where females mate with males based on size.❌

false

Hardy-Weinberg assumption is not violated for an instance where mating is not random as seen in this scenario.

3. A population of birds with no genetic mutations that often mate with members of neighboring bird populations.❌

False

Hardy-Weinberg assumption is not violated for where gene flow is seen among population in this scenario.

4. A large and isolated population of squirrels in a relatively stable environment in which no genetic mutations are occurring and mating between males and females is random.✔

True

Hardy-Weinberg assumption is violated for in this situation due to large population size.

5. A small population of spiders living in an environment that strongly favors larger individuals.❌

false

Hardy-Weinberg assumption is violated for a small population and natural selection occurring as its obvious in this case.

There are five primary Hardy-Weinberg assumptions:

A. no mutation,

B. random mating,

C. No gene flow,

D. infinite population size,

E. No selection.

If the assumptions are exempted in a gene, the population of that gene might undergo evolution causing a resultant change in the gene's allele frequencies.

Answer 2

For each population description, the Hardy-Weinberg assumption is violated -

• 1. Large population size  
• 2. random mating  
• 3. no gene flow  
• 4. no mutation  
• 5. no selection

1. A small and isolated population of seals living in a stable environment with no genetic mutations. - According to Hardy-Weinberg population should be a large population size.

2. A large population of fish where females mate with males based on size. - mating should be random mating for the Hardy-Weinberg population.

3. A population of birds with no genetic mutations that often mate with members of neighboring bird populations. - No gene flow is shown here that violates the Hardy-Weinberg population

4. A large population of squirrels in a stable environment in which mating is random and the mutation rate is very low but constant. - No mutation.

5. A population of spiders living in an environment that strongly favors larger individuals. - No selection is due to favor large individuals.

Thus,

For each population description, the Hardy-Weinberg assumption is violated -

• 1. Large population size  
• 2. random mating  
• 3. no gene flow  
• 4. no mutation  
• 5. no selection
