Vedclass · Answer

(D) Meiosis is a specialized type of cell division that reduces the chromosome number by half,resulting in the production of haploid daughter cells.$1$. It maintains the constant number of chromosomes in a species by producing gametes with half the number of chromosomes,which then restore the diploid number upon fertilization.$2$. It introduces genetic variations through the process of crossing over during Prophase-$I$,which is the raw material for evolution.$3$. Since it provides the necessary variation for natural selection to act upon,it is essential for the process of evolution.Therefore,all the given statements are correct.

Whereas the number of chromosomes is reduced to half in the first meiotic division,what is the need for the second meiotic division?

$X -$ It is very important for the process of evolution.
$Y -$ Crossing over is the exchange of genetic material between two homologous chromosomes.

Which of the following is a significance of meiosis?

During reproduction,the chromosome number $(2n)$ reduces to half $(n)$ in the gametes,and the original number $(2n)$ is restored in the offspring. What are the processes through which these events take place?
