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.
Assuming humans as the species gametes (sex cells like eggs and sperm) have a haploid number (which is to say that they have half as many as normal cells... so 23). That is 1 copy of each chromosome (22 autosomal and 1 sex chromosome). Somatic (non sex cells) have a diploid number of chromosomes (two copies of each) which for humans is 46.
