Meiosis produces cells (germ cells or gametes) with only half the DNA, or chromosomes, as normal cells (somatic cells). This is called haploid or referred to as "n" number of chromosomes. Normal body cells have doubke that, called "2n," or diploid. For humans our n = 23, so germ cells (haploid) have only 23 chromosomes, while somatic (normal body) cells have "2n" or 46 chromosomes. It is important to only carry half the number of chromosomes or DNA (n), because it is going to combine with another half (n) when sperm meets egg during fertilization. This n + n = 2n restores the diploid number of chromosomes (DNA) in a zygote, the first cell of a future embryo, fetus, and new human being.
Covalent bond because a covalent bond is when it only shares electrons and it doesn't give or lose.
Fact, BRCA genes help with cell division in the breast and prostate regions. Therefore, if they are mutated, the cell division process wouldn't function normally and possibly end up in cancer since the BRCA genes tend to be tumor suppressors (cancer is a malignant tumor).
