in human (2n=46) mitosis result 2 cell with 23 chromoses and meosis result in (n=23) 4 cell with 46 chromoses...
is this statment true ?
please help me ....
Yes, the statement is true. Let me explain why.
Mitosis is the process of cell division that results in two identical daughter cells, each with the same number of chromosomes as the parent cell. In humans, the normal diploid (2n) chromosome count is 46. So, during mitosis, a human cell with 2n=46 chromosomes will undergo division and produce two daughter cells, each containing the same 46 chromosomes. Therefore, the statement that mitosis in humans results in two cells with 23 chromosomes (2n=46) is incorrect.
On the other hand, meiosis is the process of cell division that occurs in reproductive cells and leads to the formation of gametes (sperm or eggs) with half the normal chromosome number. In humans, the haploid (n) chromosome count is 23. Therefore, during meiosis, a human cell with n=23 chromosomes will undergo two rounds of division and produce four daughter cells. These four cells, known as gametes, will each contain half the number of chromosomes, which is 23. So, the statement that meiosis in humans results in four cells with 46 chromosomes (n=23) is also incorrect. Meiosis actually results in four cells with 23 chromosomes each.
In summary, during mitosis, a cell with 2n=46 chromosomes produces two daughter cells with the same chromosome count (46 each), while during meiosis, a cell with n=23 chromosomes produces four daughter cells, each containing half the chromosome count (23 each).
