What distinguishes disruptive and directional selection pressures when both select for extreme genetic traits?
Stella [2.4K]

Answer:

Yes both are different. In directional selection one of the extreme traits is favored, whereas in disruptive selection both the extreme traits are favored.

Explanation:

Directional: If selection acts to eliminate one extreme form and supports the other extreme then the peak shifts in the direction which is selected by the nature.

Disruptive: If the selection does not favor the mean character value, rather favors both the peripheral character values then this kind of selection is called disruptive selection.

________ is a process that creates genetic variety in cells. (2 points)
Zigmanuir [339]

Answer:

B

Explanation:

I believe it is meiosis because there are two parts in which it helps to increase genetic variety. In prophase 1, the genes cross over, which increases the variety. Also, the chromosomes are assigned randomly in Metaphase 1.

Hope this helps:)

Why didnt the present shapes of the continents fit perfectly into a supercontinent
kirill115 [55]
The borders (coastlines) of the continents underwent a number of changes since the split. Often, chunks of land were washed away with water, slowly or in bigger portions. The coast was generally "smoothed" by the ocean currents too, and in some places more land was added with the material that the ocean currents brought.

Then, the tectonic plates continue to move, so this adds to the changes of the shape of the continents.
