Correct Answer - B
The daughter cells differ from parent cell as well as amongst themselves due to the segregation and crossing over taking place in them. Meiosis-I brings gene recombinations and haploidy of number of chromosomes. Crossing over during pachytene produces new combinaton of genes and is the major source of new genetic variations in the sexually reproducing organisms.
Anaphase -I results in segregation of Mendelian factors, essential for sexual reproduction, it also introduces genetic variability.
