Document Summary
Genes- storage of genetic structure of an individual: dna. Gametes- male and female reproductive cells (sperm and egg) Dominant-recessive genes principle- which genes will be expressed aka gene interaction. Imprinting- when a gene from a mother or father is not expressed. Polygenetic inheritance- multiple genes combine to create one particular trait; ex: diabetes, alcoholism. Alleles- genes that form pairs and develop certain characteristics. Gene x environment interaction- interaction between dna and the environment. Epigenetic view- how development is a relationship between heredity and environment; ex: intelligence. Multifactorial transmission- traits that develop through combination of genetics and environment. Norm of reaction- phenotypes that are expressed due to environmental factors; ex: weight. Passive genotype-environment correlations- parents create an environment for their child *encourage the child ex: parents show emphasis on education. Evocative genotype-environment correlations- child"s genes elicit and evoke a particular environment ex: child is outgoing and evokes particular behavior from other individuals.
