For each population description, identify which Hardy-Weinberg assumption is violated?
zavuch27 [327]

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.

<h2>Proportion of mottled fish </h2>

Explanation:

  • A predator can be defined as an organism that makes the other organisms die to obtain them as food. Prey is the living being which is typically inferior and killed by the predator. Adaptation is a change in the physiology, morphology and genetic makeup of the organism which makes it suitable for survival in an unfavorable environment. Natural selection is the differential survival and reproduction of the organisms which exhibit better traits over the others
  • The population of the mottled fish is likely to increase due to natural selection. As the mottled fish color pattern match with that of the mottled background of the bottom of the lake. This will help the mottled fishes to camouflage the predator wading birds. These mottled fishes will remain undetected from the predator wading birds. The trait of the mottled pattern will be adapted by the light sandy brown fishes and the trait will be passed on the next generation as well. Hence, the proposition of the mottled fish will increase
  • Hence, the right answer is "the proportion of mottled fish will increase over time"
