Question

if bacteria could survive in hotsprings, ice caps etc then which type of reproductive modes either asexual or sexual has better chance of survival

Answer 1

Hii..
If bacteria are surviving in typical conditions then asexual reproduction gives a better chance for survival as it is fast and produces more progeny at once..

hope this helps!!

Answer 2

Sexual mode as it produces variations 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.
