Which increases the rate of speciation? a) asexual reproduction b) higher gene flow c) reproductive isolation d) high dispersal abilities

Ans.

Speciation is defined as an evolutionary process that leads to development of new species from an ancestral species. Rate of speciation increases due to reproductive isolation, which prevents mating between members of different species to accumulate genetic differences in the population. over time, it leads to arise of new and different species.

Thus, the correct answer is 'option C). reproductive isolation.'

a tetrad is the foursome during meiosis made by two homologous chromosomes that have each already replicated into a pair of sister chromatids.
