Document Summary
The moment babies are born, they differ from each other physically and in behaviour. Transactions among a vast array of hereditary and environmental factors begin before birth between genes and the environment make each baby unique. What provides a framework for exploring the interactions of genes and environment is the concept of genotype and phenotype: The sperm and the egg unite together to create a new living organism that has the potential to develop into a human being zygote. Zygote- new organism, results from the union of male and female gametes, or reproductive cells, each other which carries genetic information. Ovum- (or egg) the largest human cell, is about 90 000 times as heavy as the sperm that penetrates it (smaller than the punctuation period. ) Sperm- the smallest of all human cells, shape of a head, where the hereditary information is, with a whip-like tail, uses to propel itself through the woman"s reproductive system in search of the ovum.
