3. How does speciation start to take place on a genetic level between two isolated populations?
A) Large numbers of mutations occur.
B) Allele frequencies change in different ways.
C) New genes are added to one group.

Answers

Answer 1
Answer: 1) C
A population has to be isolated for speciation
2) D
Different species are incapable of reproducing with one another
3) D
When a population is contained, the recessive alleles can become dominant within the population
Answer 2
Answer:

The 3rd question is actually B. Allele frequencies change in different ways

Which of the following is an example of a disease that is properly matched with one of its environmental risk factors? High blood pressure—genetics
Arteriosclerosis—diet
Hemophilia—poor nutrition
Anemia—family history

Answers

Answer: Arteriosclerosis—diet

Explanation:

The disease like is directly related to the diet that the person eats in his daily life. Some of the diseases are caused by the environmental problems such as lifestyle, diet and many more factors.

This disease is caused by the unhealthy lifestyle and food that we consume. More fatty food and no physical activity can lead to the blockage in the arteries of the heart.

The thickening of the blood causes blockage in the artery and can cause a medical condition known as arteriosclerosis.

The Answer is B ; Arteriosclerosis - Diet.

in order to use the Hardy-Weinberg equation to calculate genetic variations in a population which of the following conditions must exist in the population

Answers

Answer: All organisms must reproduce.

Explanation: Trust me G

APEX. Just trying to help people out who also have this question.

Population of living creatures or living organisms.

Because what can reproduce is a living creature/organism.

Further explanation

The Hardy-Weinberg Principle states that alleles and genotype frequencies in a population will remain constant from generation to generation without any other evolutionary influence. These influences include perfect pairing, mutation, selection, genetic drift, gene flow, and Meiosis steering.

The seven assumptions underlying the Hardy-Weinberg equation are as follows:

  • Such organisms are diploid
  • only reproduce sexually
  • generation that does not overlap
  • random marriage
  • infinite population size
  • same frequency alleles in both sexes
  • no migration, mutation or selection
