Hey there,
→We know that offsprings receives chromosomes from the two different parents.
→So , this is obvious that the progeny produced will have variations as they aren't genetically different.
→ And because of variation in them they are highly adapted to the Changing environment.
→ So, if any calamity occurs then there's possiblity that entire generation destroys and hence the Extinction of Species.
→And as we have an example of Hemophilia ,so this statement is not always true.
Thanks!

Answer:
Sexual reproduction is said to occur when two gametes fuse. This leads to the production of the offspring that are genetic variants of the parents, and therefore, are able to survive better.
However, the organisms produced by sexual reproduction do not always survive more than those produced by asexual reproduction. Sometimes, the organisms produced by asexual reproduction survive better than those produced by sexual reproduction. Also, it is a fairly quick process and consumes less energy and time.
