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.
If the egg and sperm each had 23 chromosome pairs, their union would result in a zygote with 46 pairsâdouble the usual number. Theoretically, this cell would then grow into a person with 46 pairs of chromosomes per cell (rather than the usual 23 pairs).
