Question

Explain the factor depends for speciation. ​

Answer 1

Explanation:

Factors that lead to speciation include genetic drift, natural selection, geographical isolation, mutation. Geographical isolation is not a major factor in the speciation of a self-pollinating plant species as pollination occurs between the reproductive organs of the same flower.

Answer 2

Factors responsible for speciation.

Explanation:

• Speciation is the process of formation of new species from existing species.
• It means splitting of species into two or more genetically distinct species.
• It is of two types Allopatric and sympatric.
• There are five main factors responsible for speciation.
• Geographical isolation - barriers like rivers, deserts ,mountains etc seperate species into several groups , it is the most significant causes of speciation.
• Genetic drift- change in pattern of gene flow,also  non-adaptive mutations play a vital role in forming new species.
• Natural selection - Newly formed species passes their characters  on to their future offsprings.
• Reproductive isolation-  Organisms lose the ability to reproduce and create a different kind of species.
• Hybridisation - production of new species by artificial process.
