Question

In the meiotic cell division,56 daughter cells are produced by two successive divisions in which (1)First division is equational,second is reductional (2)First division is reductional,and second is equational (3)Both divisions are reductional (4)Both divisions are equational

Answer 1

Answer:Reductional then equational

Terminology

Reductional division: meosis since no. Of chromosomes are reduced in daughter cell

Equational no.: mitosis (or meosisII) Of chromosomes are same as in parent cell

Explanation: for meosis to occur assume a cell with ploidy 2n it first undergoes meosis to form cell of ploidy n then again goes under mitosis to form cell of ploidy n . hence 4 cell are produced from 1 cell ,

Then on dividing 56/4 =14

These are no. Of parent cell
