Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Would a population be more likely to survive a changing environment if they reproduced sexually or asexually?
A
Sexually
B
Asexually
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Sexually reproducing organisms have a higher probability to survive because sexual reproduction incorporates variations, which can be beneficial and help the organism to adapt to changing environmental conditions.

Detailed explanation-2: -On the other hand, the rapid rates of asexual reproduction may allow for a speedy response to environmental changes if individuals have mutations. An additional advantage of asexual reproduction is that colonization of new habitats may be easier when an individual does not need to find a mate to reproduce.

Detailed explanation-3: -The offspring of sexually reproducing organisms are all genetically unique. Because of this, sexually reproducing organisms may have more successful survival of offspring in environments that change than asexually reproducing organisms, whose offspring are all genetically identical.

Detailed explanation-4: -Whereas asexual reproduction produces genetically identical modules that may prolong the survival of the genotype, sexual reproduction enables genetic recombination and production of new coral genotypes to enhance fitness and survival of the species.

Detailed explanation-5: -2) If the environment is stable (unchanging), and a particular organism is very well adapted to it, asexual reproduction has an advantage over sexual reproduction. If however, the environment changes (as we know it usually does), then sexual reproduction is favored since it allows for new combinations of genes.
