Question

list any three responsible for speciation and explain each

Answer 1

Speciation is the process in which one or more species arise from previously existing species due to reproductive isolation of a part of its population.

Factors responsible for speciation:

• If Gene flow stopped ,subpopulations become genetically isolated.
• Mutation plays a role in speciation.
• Changes in allele and genotype frequencies within the populations, by natural selection
• Genetic isolation leads to the formation new species.
• Geographical isolation leads to reproductive isolation and hence speciation.
• Sometimes cross between two unrelated species (Genetic Engineering) can also lead to speciation.
