Answer: This is called the founder effect.

Explanation:

Founder Effect Definition

The founder effect refers to a situation in which a larger group breaks into smaller groups as people of that group move to other locations or spread out to live in different places or states.

The traits of the original group get lost along the way , the smaller group tend to inherit the traits from the individual who original founded the smaller group.

As the group get smaller the more it loses the traits they had from the original larger group.

If the individuals who were the first to isolate from original large group did not have the same alleles carried by most of the members in the original large group then the new smaller group will not have those alleles which yields the founder effect.

The family end up being genetically different, the founder effect is caused by geographic isolation which create a gap that restrict an interaction that may bring back the former alleles. It can also due to mutation.

Identify and describe the agricultural techniques used by Egyptian farmers. How did these techniques affect heir economy?
Mandarinka [93]

The Nile played a significant role in supporting Egypt's predominantly agrarian economy. The river brought excellent silt and flooded the crops that were next to it.

Ancient Egypt's culture owed a lot to the Nile River and its reliable seasonal floods. The Egyptians were able to create an economy based on abundant agriculture thanks to the river's regularity and the region's fertile land.

Grain was the first crop grown in Egyptian agriculture following the flood season (also known called the Season of the Inundation). Ancient Egyptian farmers would plant vegetables after harvesting the grain. Large grain storage were built by the Egyptians to keep the grain dry and fresh.
