Detailed explanation-1: -When a cell with 40 chromosomes undergoes meiosis, each of the four resulting cells has. Solution : (a) 20 chromosomes, because in merosis cell dicison chromosome number becomes halved.
Detailed explanation-2: -Each daughter cell will have 30 chromosomes.
Detailed explanation-3: -Thus, if a diploid cell contains 40 chromosomes, then the haploid cell will contain 20 chromosomes. During meiosis, a diploid cell undergoes two successive rounds of cell division to form four haploid cells.
Detailed explanation-4: -Meiosis is also called reduction division. This type of cell division is involved in formation of gametes. The number of chromosomes is reduced to half at the end of meiosis. So, a cell having 20 chromosomes will give rise to four daughter cells having 10 chromosomes after meiosis.
