Answer:
Asexual reproduction is a mode of reproduction in which only one parent is involved to reproduce offspring. In asexual reproduction,the offsprings produced are exact copies of their parents. It is generally observed in very small sized organisms. Binary fission, Budding, Fragmentation etc.
Explanation:
The answer is reproductive isolation. Reproductive isolation ensures members of different species do not produce offspring. In this case, geographical separation is ensuring that individuals from the two different populations are not able to mate with each other. Eventually, through different selective pressures, the two populations will diverge sufficiently in genotype to become distinctly different.
Answer: Gene Pool
Explanation:
Gene pool is the collection of all the gene and various allelic form of those gene within a population.
Variation naturally occurs among the gene of members of the same species that interbreed.
Gene pool It is therefore the total number of gene of all the members among the population of a particular species. Gene pool is used to determine the level of mutation, variation, genetic diversity among members of a population.
To show he presence of a trait you would need to follow it through multiple generations in a pedigree.
