Question

Distinguish between equational division and reduction division

Answer 1

HIYA !

here's the answer :)

EQUATION DIVISION or MITOSIS

• it occurs in somatic cells
• nucleus divides only once
• two daughter cells are formed
• daughter cells are diploid
• it occurs more frequently
• daughter cells form somatic organs
• there is only 1 prophase, 1 metaphase, 1 anaphase, and 1 telophase
• number of chromosomes aren't changed in the daughter cells
• chromosome number doubles at the beginning of each cell division
• no crossing over in chromosomes

REDUCTION DIVISION or MEIOSIS :

• it occurs in germ cells
• nucleus divides twice
• 4 daughter cells are formed
• daughter cells are haploid
• it occurs less frequently
• daughter cells form gametes
• there are two of each phase and five sub-phases in prophase-I
• number of chromosomes are reduced to half
• chromosome number is not doubled,,,,it doubles after the end of 1st meiotic division
• crossing over occurs in chromosomes
