Document Summary

> scientists believe that both nature and nurture play an equal role in the development of a human being. The interaction between nature and nurture are very important. ex) boy with downsyndrome (nature: negative, nurture: good), vs. starving african boy (nature: good, nurture: bad) We have 46 chromosomes in every cell, except the egg and the sperm cell. More speci cally, they carry this info in the form of dna molecules. > contain the instruction that give organizing structure and shape (ex: eye colour, hair colour etc) It is possible for genes to be dormant. > it can also sometimes take only one gene to make a huge difference ex) two dogs-> one super big and one very small: this is the result of one gene. > contrarily, sometimes it takes multiple genes to create circumstances. This is referred to as gene complexes. ex) obesity-> 2000 genes are found to contribute to this.
