Meiosis is evolutionary significant because it results in

A

genetically similar daughters

B

four daughter cells

C

eggs and sperms

D

recombinations

Text Solution

Verified by Experts

The correct Answer is:
D
Recombination takes place in meiosis but still Meiosis maintains the chromosome number constant. It produces haploid gametes by reducing the chromosomes number to half. Crossing over produces new combination of linked genes and is major source of genetic variation.
Also, distribution of bivalents which is at random in metaphase-I provides the secondary source of genetic variation in the organisms and is essential for speciation and evolution.

Meiosis is also alled reductional division because it halves the chromosome number in the daughter cells than those in the parental cell. It is so as the parental cell divides twice, while the chromosomes duplicate only once. Mciosis is of three types on the basis of period and site of occurrence of metosis.

Give its significance, (in) State one difference between gametic meiosis and zygotic meiosis.
