Question
Meiosis-I is reductional divion. Meiosis -II is equational division due to
Options
A.pairing of homologous chromosomes
B.crossing over
C.separation over
D.disjuntion of honologous chromsomes
Solution
Meiosis-I is called heterortypic division as the two chromatids of a chromosome became genetically different due to crossing over. Number of chromosome is reduced to half,hence, called reduction division. Meiosis-II is just like mitosis but occurs in haploid nuclei, it is called honotypic or equational division as the chromosome are distributed equally into daughter cells and chromosome number remains the same in daughter cells.
