Many things. Just physical differences, a mouse is not going to breed with an elephant. Behavioral difference, such as mating dances, calls and the like. Temporal differences, such as one organism is diurnal and the other is nocturnal, or seasonal differences. These are called prezygotic barriers to reproduction.
Postzygotic barriers can be as simple as a sterile match, such as horses and donkeys.
Then there is just physical barriers, such as mountains and water barriers.

What evidence suggests that there may have been interbreeding between East Asian populations and Neanderthals?
Recent genetic studies have found that modern East Asian populations have a small percentage of Neanderthal DNA in their genomes, indicating interbreeding between the two groups. This suggests that there was likely some level of interaction and interbreeding between East Asians and Neanderthals in the past.
What is interbreeding and how does it impact genetic diversity in biological populations?
Interbreeding is the mating between individuals of different species or populations. It can increase genetic diversity by introducing new genetic variations into the population. However, excessive interbreeding can lead to a loss of genetic diversity and potentially reduce the population's ability to adapt to changing environments.
What is it called when two populations share genetic information?
Genetic exchange between two populations is called gene flow. It can occur through interbreeding or the transfer of genetic material through other means, such as migration or hybridization. This exchange of genes can help increase genetic diversity within populations and lead to evolutionary changes.
How does speciation take place?
several generations
What are the two factors that affect speciation?
The two factors that affect speciation are isolation, which can be geographic or reproductive, and genetic divergence, where populations accumulate genetic differences that prevent interbreeding. These factors can lead to the formation of new species over time.
Why do geographic isolation cause speciation?
It prevents the two populations from interbreeding. :) -Apex-
When does behavioral isolation occurs?
when two populations are capable of interbreeding but have differences in courtship rituals.

Explain why individuals in population a stop seeing individual from population b as potential partners?
This will happen if the two populations diverge genetically so that either their appearance or their behaviour changes. Once differences have built up which prevent interbreeding the two populations have become two different species.
20000 years ago two populations of the black-tailed rats became separated from each other thus preventing their interbreeding The condition described is?
selective breeding.

This exchange of genes can help increase genetic diversity within populations and lead to evolutionary changes.
Two factors that keep populations stable?
Birth and death.
Two populations that inhabit the same area but remain genetically distinct?
Two populations could remain genetically distinct despite inhabiting the same area if they have limited interbreeding due to mate choice, physical barriers, or different ecological niches. Over time, this can lead to genetic differences accumulating between the populations, resulting in genetic distinctiveness.
