Document Summary

Hippocrates suggested that semen contains not body parts, but some sort of design for the formation of the offspring. This idea was confirmed by gregor mendel, a monk whose research with garden peas in the 1860s marked the beginning of modern genetic theory. Heredity involves the passing on of specific organic factors. These factors might produce visible characteristics in the offspring, or they might simply be carried for possible transmission to another generation. Genotype: the specific genetic makeup of an individual. Phenotype: the observable characteristics produced by that genetic endowment. It can be affected by other genes and by the environment. Chromosome: a tightly coiled molecule of dna that is partly covered by protein. The dna portion of the chromosome carries the hereditary blueprint in units is called genes. Alleles: alternative forms of a gene that produce different characteristics. It magnifies the number of possible variations in a trait that can occur.
