This represents the example of founder effect.

The founder effect is a term in genetics that describes the loss of genetic variation as a result of new population formation by a very small number of individuals from a larger population. Small group of migrants (the afrikaner population of south Africa) that is not genetically representative of the larger population (Europe population) forms a new population with lower genetic variation.

<u>Answer</u>: Founder effect.

<u>Explanation</u>:

  • The <em>founder effec</em>t is caused when a small group of individuals becomes separated from a larger population and move into a new area. This smaller population, moving to a new area forms the founder population.
  • Since a new population is established from a smaller population it leads to a loss of genetic variation and, this effect is known as founder effect and this is the reason why<em> Familial hypercholesterolemia is more frequent in the afrikaner population </em>

What are pontential impacts of pollution on a watershed
garri49 [273]

Answer:

Aquatic life quickly suffers the effects of watershed pollution, while new pollutants introduced into ecosystems alter wildlife habitats. This reduces biodiversity by eliminating some species and introducing new, invasive ones that destroy the native species.

We breathe more quickly and deeply when we exercise. Why does this make sense? Select all that apply. a) Because when we exercis
storchak [24]

Answer:

a) Because when we exercise, we hydrolyze more ATP to ADP and Pi, and O2 is necessary for the hydrolysis, so we increase our intake of oxygen.

c) Because when we exercise, we produce more CO2 and increased ventilation is necessary to rid ourselves of CO2.

d) Because when we exercise, we use more ATP, and additional O2 is necessary to generate sufficient ATP.

Explanation:

During exercise , our body needs more energy in the form of ATP. This ATP comes from break down of food materials in the mitochondria of the cell during cellular respiration. With the addition of oxygen, more ATP is produced during respiration and this ATP is used by the body. With ATP, carbon dioxide is produced as a waste material which can be removed by exhaled out during breathing.
