Genetics


Have you ever wondered how you have the same hair color as your mom or the same eye color as your dad?

When a sperm fertilizes an egg, their nuclei fuse together, and you now have a zygote which contains a full set of 46 chromosomes-23 from each parent. The combination of the genes you inherit, as well as envirnmental factors in utero and after you are born, will determine what you look like, your intelligence level, how prone you will be to certain diseases, and so forth...

How is genetic information passed on from parent to child?

Sperm Chromosomes contain tightly wound coils of DNA, sections of which are referred to as "genes."

  1. i must say i like your guys' background very intereasting! i posted once to this page but it got deleted due to my lack of sense to hit post comment the second time. but i thought it would be intereasting to know more about the genes and that the kids would also like to hear about phenotypes and genotypes its really an intearesting thing and a fun thing to do with them would be make a creature! but i enjoyed reading the information you guys put. sci. would diff. be my second choice to do if i wasnt so excited to teach elementary and be able to teach everything! Good job guys!
