Given below are the two statements : one is labelled as Assertion (A) and other is labelled as Reason (R).
Assertion (A) : Meiosis is the mechanism by which conservation of specific chromosome number of each species is achieved across generation in sexualy reproducing organism, even though the process, per se, paradoxically, result in reduction of chromosome number by half.
Reason (R) : Meiosis involves pairing of homologous chromosomes and recombination between non sister chromatids of homologous chromosomes.
Both (A) and (R) are true and (R) is the not correct explanation of (A).
A true → meiosis maintains chromosome number across generations
R true → pairing and recombination occur
Link → this does not explain conservation; reduction + fertilization does
The interphase nucleus has a loose and indistinct network of nucleoprotein fibre
