mytosis creates sex cells - either eggs (in girls) or sperm (in boys). They have 1/2 the number of chromosomes. When an egg and sperm combine, they create one full cell - one half plus one half = one whole. The fetus is created from that one full cell.
The chromosome number is halved during cell division in meiosis, not mitosis.
The chromosome number is halved during the process of meiosis in the cell cycle.
The chromosome number is halved during the first stage of meiosis, known as meiosis I.
In Anaphase I
During meiosis, the chromosome number is reduced by half. This is because the cell undergoes two rounds of division, resulting in four daughter cells with half the number of chromosomes as the parent cell.

During meiosis, the chromosome number decreases by half. For example, if a human cell with 46 chromosomes were to undergo meiosis, the result would be four daughter cells with 23 chromosomes in each.

No. Meiosis results in halving of chromosome number. Chromosome number after one round of meiosis is half that of original chromosome number. Generally, meiosis takes place during gamete formation. So when two gametes fuse, they lead to restoration of the chromosome number. Hence chromosome number can be maintained in sexually reproducing organisms.
In Anaphase I
During meiosis, the chromosome number is reduced by half. This is because the cell undergoes two rounds of division, resulting in four daughter cells with half the number of chromosomes as the parent cell.
During mitosis, the chromosome number remains the same. The cell duplicates its chromosomes before dividing, so each daughter cell receives the same number of chromosomes as the parent cell.
During cell division, the chromosome number remains constant. In mitosis, each daughter cell receives an identical set of chromosomes to the parent cell. In meiosis, the chromosome number is halved to produce gametes with half the number of chromosomes as the parent cell.
B. It is important for chromosomes to condense during mitosis to facilitate chromosome movement. Condensed chromosomes are easier to separate and move to opposite ends of the cell during cell division, ensuring that each daughter cell receives the correct number of chromosomes.
During meiosis, the chromosome number decreases by half. For example, if a human cell with 46 chromosomes were to undergo meiosis, the result would be four daughter cells with 23 chromosomes in each.
