What is artificial selection

Artificial Selection Answer Artificial Selection is the breeding of certain traits (better traits) over other traits. For example, breeding a good male horse with excellent racing qualities with a healthy female horse so that the offspring will have the desired traits such as the racing qualities. Another example is breeding good size fruits or vegetable together to keep on getting the good size.

Selection done by humans looking to maximize traits in animals under domestication. These traits are not always for the benefit of the organism though. Men raise these animals and mate the ones they think will breed true for a man favored trait and cull the rest of the organisms by killing them, or by not allowing them to breed.

What tends to increase genetic variation in a population

mutation apex answers

Why are vestigial structures not removed by natural selection

Vestigial structures do not harm the organism. Nature selects against only harmful traits.

How does reducing gene flow cause speciation

It allows divergence to occur

It allows populations to become genetically different.

When is genetic drift a major factor in evolution

When there is low gene flow

When there is no selective pressure

When there is a bottleneck

What is the source of energy that heats earth's surface

The sun is the source of energy that heats earth's surface. Radiation from the sun comes through the atmosphere, largely unhindered, and warms the surface of the earth.

What do directional selection and disruptive selection have in common-

directional selection and disruptive selection both decrease genetic variation - apex
