For any given trait, one gene variation (allele) is received from the father and one from the mother. The expression of these alleles determines the phenotype, whether dominant or recessive. In biology and genetics, this external expression (or ...

We will explore some of these single gene traits in the laboratory. Use a lab partner to help you determine your phenotype for the traits listed.
Jan 29, 2024 · This approach assumes behavior is determined by relatively stable traits, the fundamental units of one’s personality. Traits predispose one to act in a certain way, regardless of the situation. This means that traits should remain consistent across situations and over time, but may vary between individuals.

Traits can be qualitative (such as eye color) or quantitative (such as height or blood pressure). A given trait is part of an individual’s overall phenotype.
Dec 20, 2023 · The interaction between dominant and recessive genes determines the traits that will be expressed in an individual. Dominant genes always overshadow recessive genes and determine the traits that will be observed, while recessive genes are only expressed when an individual has two copies of the recessive allele.

Psychologists have investigated hundreds of traits using the self-report approach, and this research has found many personality traits that have important implications for behaviour. You can see some examples of the personality dimensions that have been studied by psychologists and their implications for behaviour in Table 12.1, “Some Personality Traits That Predict Behaviour,”.
