Document Summary

Suggested that semen contains not body parts, but rather some sort of design for the formation of the offspring. Genotype: the specific genetic makeup of an individual. Phenotype: the observable characteristics produced by that genetic endowment. It is estimated that about half of all genes target brain structure and function. Polygenic transmission: a number of genes working together to create a particular phenotypic characteristic. Recombinant dna procedures: researchers use certain enzymes to cut the long threadlike molecules of genetic dna into pieces, combine them with dna from another organism, and insert them into a host organism, such as a bacterium. Gene knockout: a procedure that alters a specific gene in a way that prevents it from carrying out its normal function. This can be used in psychology to study how certain neurotransmitters affect the brain and functionality. Genetic engineering allows scientists to duplicate and alter genetic material or, potentially to repair dysfunctional genes.
