So before you go in for your oil change, dig out your ownerâs manual and see what it says. And when the mechanic slaps on a sticker that gives the next change date in 3,000 miles, ask questions. And then, go get the car washed. Thatâs one thing that always seems to be needed.
The somatic cells of an animal species contain a specific number of chromosomes that must be maintained for the cells to work properly. In humans, they each contain 46 chromosomes, which includes 22 pairs of homologous chromosomes and one pair that is non-homologous.
However, your germ cells (sperm in males and egg in females) have half the number of chromosomes in your somatic cells (the cells of the body other than the germ cells), that is 23 chromosomes. This is because 23 from the sperm + 23 from the egg= 46 in the zygote = 46 in the adult human. This halving from 46 to 23 chromosomes is made possible by a process termed as meiosis.
