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.
If it is a human zygote with no mutations, then it will contain 46 chromosomes. Each parent gives the zygote 23 chromosomes. All human gametes without mutations contain 23 and when joined during fertilization they form a zygote with 46 chromosomes. However, chromosome number varies by species, for example a normal pigeon zygote would have 80 chromosomes.
In the case of humans, this means that parent cells have two chromosomes and gametes have one. During fertilization, gametes from the sperm combine with gametes from the egg to form a zygote. The zygote contains two sets of 23 chromosomes, for the required 46.he fatherâs sperm contains about half X and half Y chromosomes. The sperm are the variable factor in determining the sex of the baby. If the sperm carries an X chromosome, it will combine with the eggâs X chromosome to form a female zygote. If the sperm carries a Y chromosome, it will result in a male.
