Gene flow between populations can hinder the development of genetic differences necessary for speciation. Additionally, strong environmental pressures favoring specific traits in a population can limit genetic variation and prevent the emergence of distinct species. Lastly, hybridization between different groups can also counteract speciation in sympatric populations.

What is Geographical barriers?
Some artificial geographical barriers that exist include trenches dug around flat grounds to deter the movement of tanks and military transport vehicles. Others include walls, such as the great wall of China.
Why do LEDCs often suffer worse from conflicts?
LEDCs often suffer worse from conflicts due to factors such as limited resources, weak infrastructures, and poorer access to healthcare and humanitarian aid. Additionally, conflicts in LEDCs are sometimes fueled by historical colonial legacies, political instability, and competition over scarce resources, exacerbating the impact on vulnerable populations.
In the Midwest drought is most likely with a circulation pattern in the westerlies?
In the Midwest, drought is most likely to occur when there is a persistent high-pressure system in the westerlies that prevents moist air from moving into the region. This lack of moisture can lead to below-average precipitation levels and prolonged dry conditions, contributing to drought.
Why no D climates in the southern hemisphere?
D climates, which are characterized by mild winters, are not found in the southern hemisphere because there is less landmass in the southern hemisphere to create the necessary conditions for these climates to exist. The lack of significant landmass at high latitudes in the southern hemisphere prevents the formation of D climates.
What were the advantages of terrace farming?
Terrace farming helped prevent soil erosion by reducing water runoff, allowed for agriculture on steep slopes, and conserved water by capturing and distributing it evenly across the terraces. It also increased agricultural productivity by creating more arable land in hilly or mountainous regions.
Why do geographic isolation cause speciation?
It prevents the two populations from interbreeding. :) -Apex-
Why does geographic isolation cause speciation (Apex)?
it prevents gene flow between populations
If a population becomes isolate from other populations of the same species and then genetic divergence occurs that prevents them from breeding with other populations what is it called?
It is called speciation.

Why does geographic isolation cause specilation?
It prevents the two populations from interbreeding - APEX
A prevents actions from occurring?
inhibitor
What is the most important factor that holds a gene pool together and prevents speciation?
gene flow
How does predation cause stability ecosystem?
it prevents populations from getting to high
Explain how isolation helps speciation?
Reproductive isolation prevents variations from spreading throughout the entire population. Since genetic variations basically occur randomly, the chances that the same variations will occur in both reproductively separated subpopulations are vanishingly slim. Thus, genetic divergence between both subpopulations will occur, and this may eventually lead to speciation. Isolation stops populations of the same species from interbreeding. This results in separate breeding among populations and genetic differences become more pronounced with each generation.
What prevents a pure monopoly from occurring?
Monopolies are usually bad for society so governments either nationalise them or regulate them.
Are tracheids alive at maturity?
Dead , their walls become lignified. Lignin is waterproof and prevents osmosis occurring so the cell dies.
How does the presence of predators help keep an ecosystem stable?
The predators keep prey populations balanced.
