Question

how do sexual reproduction help in re-establishment of number of chromosomes in the new generation ?

Answer 1

Answer:

Explanation:

Reproduction maintains the number of chromosomes specific to a species in each generation. ... So when these germ-cells from 2 different individuals combine during sexual reproduction to form a new individual, it results in re-establishment of the number of chromosomes and the DNA content in the new generation.

Answer 2

When the gametes fuse during fertilization, the resulting new generation organism gets one pair of chromosome (Haploid) from each parent and thus the chromosome becomes diploid. Thus, the full number of chromosomes is re-established and the specific chromosome number of a species is maintained.
