Biology

timama [110]3 years ago
3 0

Answer:

the amount of genetic variation in a population.

Explanation:

The proportion of the members of a population possessing beneficial allele due to natural selection will increase with time while the proportion of those possessing a harmful allele will decrease with time. After many generations, all the members carrying the harmful allele will die out leaving only those with the beneficial allele. The result is a genetic variation of the population with time.

What is the name of the groove that forms in the middle of a dividing plant cell
mrs_skeptik [129]

Plants have cell walls, so cytokinesis cannot go on with a cleavage furrow, but instead, a cell plate  forms across the cell in the location of the metaphase plate.

There is no distinct groove along the cell plate as the cell divides because of the rigid nature of the cell plate or new cell wall.

A plant cell divides differently from an animal cell which forms a clear cleavage furrow because it only has a flexible cell membrane and not a rigid cell wall like plants.

The cell plate in plant cells is formed by membrane bound vesicles which migrate to the center of the cell where the metaphase plate used to be and fuse together to form a cell plate.
