Why the amount of DNA does not get double during sexual reproduction
Answers
Answer:
The amount of DNA does not get doubled during sexual reproduction as the gametes contain half the number of chromosomes that a somatic cell contains. ... These half chromosomes of the sperm fuse with the egg and create the 46 numbers of chromosomes in a zygote.

Answer:
During sexual reproduction the amount of DNA does not get doubled because :---
●We know that gametes are always haploid so the sperm from man has 23 chromosomes and similarly the egg has 23 chromosomes, so when they fuse they ive rise to organism having 46 chomosomes hence restoring amount of DNA and number of chromosomes.
●During reproduction the germ cells have half the number of chromosomes and DNA as compared to non-reproducing cells.
●As the offspring receives only one copy from each parent,thus maintaining amount of DNA .
●If it gets double then each next generation would end up having double amount of DNA as previous generations so af end a stage will be there when there will only be DNA and no other cells.
●Hence to resolve this problem the DNA does not get doubled in next generation.
