Simplifying things greatly (as this guide aims to do, mostly), quantum dots are incredibly small particles. They range between 2 to 10 nanometers in diameter, which is equivalent to 50 atoms. Yes, atoms. You can't measure these things using your old school shatter proof ruler. It's this small size that gives quantum dots the unique properties to improve our tech.
A zygote is formed when the male gamete (sperm) fuses with the female gamete (ova). Each gamete (regardless of the sex) is marked with an n; indicating it to be a haploid. Therefore; sperm (n) + ova (n) = zygote (2n) [A zygote is a diploid; 2n]. n = 23 chromosomes.
So there are 22 autosomes in a human gamete (spermatozoon or ovum). In the zygote and all the body cells subsequently formed from the zygote, there are two sets (the diploid condition) and therefore 44 autosomes (two genetically different versions of each of the 22). 44 <br />- - -<br />In humans, there are 23 chromosomes in one <b>set</b>.
