Question

write a thoughtful and educated comment on why sexual reproduction is advantageous for the survival of human populations.

Answer 1

The most significant comment to describe the advantage of sexual reproduction for survival of human population is that, it leads to variations.

​​​Progenies are different from their parents and also one progeny is different from the other, even from the same parent. This is called in variation. These variations are caused due to reombination and crossing over which occurs during meiosis 1 and independent assortment of chromosome which also occurs during meiosis 1 during gamete formation. It ensures that each gamete receives any one of the chromosome from a homologous pair so that gamete is a mixture of paternal as well as maternal chromosomes.

​​​​​Sexual reproduction is important for two reasons. One reason is that variations due to meisois during gamete formation helps to prevent the expression of recessive alleles which are disadvantages for the survival of the organisms. The second most important reason is that variations leads to evolution. These are the most important and only Force for evolution of species.

If you have to write the 1 line, then write, that sexual reproduction leads to variations which is the only Force for evolution.
