WitrynaHeritability is a summary parameter over loci and does not tell us about either the numbers of genes that affect a quantitative trait or the magnitude of their effects. It can change as a population evolves, for example, by selection and inbreeding, although heritability typically changes slowly with polygenic inheritance. WitrynaThere are many different arguments relating to whether intelligence is inherited or whether it is something that is developed through the environment, which is otherwise known as the ‘Nature versus Nurture’ debate. A little of this will be discussed later on, along with trying to define intelligence, heritability and how inheritance takes ...
