प्रश्न
Which species is likely to have better chances of survival - the one reproducing asexually or the one reproducing sexually? Justify your answer.
Which species is likely to have comparatively better chances of survival – the one reproducing asexually or the one reproducing sexually? Give reason to justify your answer.
उत्तर १
The organisms reproducing sexually have better chances of survival because it promotes diversity of characters in an offspring due to combinations of genes which can lead to variation whereas in asexual reproduction evolutionary change is not possible as only one parent is involved therefore no variation takes place.
उत्तर २
Organisms undergoing sexual reproduction are at advantage and have better chances of survival in comparison to the one undergoing asexual reproduction. This is because sexual reproduction involves fusion of two different types of gametes derived from two different individuals. This results in variation in the genome of progenies, leading to greater genetic diversity and thus better chances to adapt, escape or evolve through the selection pressures of the nature
