Why should gametes be produced by meiosis during sexual reproduction?
Answers
Answer:
If gametes does not produce by meiosis then there will be large scale abnormalities. ex. if gamete does not divide by meiosis. then the gamete will become haploid, then resulting offspring will have 46+46=92 ,such a new number causes severe abnormalities. chromosome number will not maintained at constancy.
Answer:
In sexual mode of reproduction,each new is the combination of DNA copies from to parents each new generation gets twice twice the amount of DNA compared to that with the previous generation but reduction division such that meiosisoccurs during gametes formation as a result germ cell have half the number of the chromosomes and half the amount of DNA set as compared to the non reproductive body cell when haploid cancel from the two parents use during sexual reproduction IT results in diploid zygote chromosomes and the the DNA content in new generation is reestablish .
