Geographical isolation prevents gene flow between populations of a species whereas asexual reproduction generally involves only one individual. In an asexually reproducing organism, variations can occur only when the copying...
(a) Humans reproduce sexually.
(b) Humans are viviparous.
(c) Fertilization is internal in human.
(d) Male and female gametes are haploid .
(e) Zygote is diploid.
(f) The process of release of the ovum from...
Functional mRNA of structural genes need not always include all of its exons. This alternate splicing of exons is sex-specific, tissue-specific, and even developmental stage-specific. By such alternate splicing of...

Geographical isolation will not be a major factor in the speciation of an organism that reproduces asexually, because it does not require any other organism to carry out reproduction.
(a) The presence of specific features, which enable a plant or an animal to live in a particular habitat, is called adaptation.
(b) The habitats of the plants and animals that...
