Is Personality Genetic? The Impact of Genes vs. Environment
WebThis is true of things such as how violent we are, and how well we get on with other people. So, even though scientists may soon be able to describe our genes in detail, it does not mean they will be able to predict our future with any real success.

WebIn the language of genetics, Mendel’s theory applied to humans says that if an individual receives two dominant alleles, one from each parent, the individual’s phenotype will express the dominant trait. If an individual receives two recessive alleles, then the recessive trait will be expressed in the phenotype. Web1. (1) Tall plant produce gametes by meiosis and the dwarf plants by mitosis. (2) Only one allele is transmitted to a gamete. (3) The segregation of alleles is a random process. (4) Gametes will always be pure for the trait. 2.
