There are 46 chromosomes in a dividing human cell. The definition of a single chromosome is whatever is attached to one centromere. During the S phase of mitosis, DNA is synthesized and doubled-so there is double the amount of DNA, but it is all attached to one centromere-so therefore it is still one chromosome. The tetrad will split into 2 chromosomes during division, each with 2 sister chromatids, thus leaving each identical daughter cell with 46 chromosomes.

In humans - 46.
It's the full set of chromosomes for whatever species you are considering.

in many cases, human cells have 23 pairs(40 six) of chromosomes... Mitosis is the cellular branch for develop and repairing of the physique.. in Mitosis, a million confirm cellular divides into 2 daughter cells each and each daughter cellular is composed of a similar volume of chromosomes as confirm cellular it somewhat is 23 pairs(40 six) of chromosomes for human beings.... In Meiosis... a million confirm cellular divides into 4 daughter cells. each and each daughter cellular incorporate 23 Chromosomes. it somewhat is 0.5 the quantity of confirm cellular... Meiosis happens in intercourse cellular.. each and each daughter cellular is observed as gamete.. after sexual intercourse.. a million gamete of male fuses with a million gamete of lady... ensuing in a cellular containing 40 six Chromosomes.. so the recent baby is composed of a similar volume of Chromosomes as the different human
