However, we know that intra-uterine variations don’t account for most of MZA similarity since DZA twins, who also share the same womb, are not nearly as similar as MZAs. 2. ...

Reading 2 – Genetic Drift Random Events

Once this happens, no additional copies of that allele exist in the population to make copies of (through meiosis) or to put into sex cells or to pas ...

Behavioural genetics
Behavioural genetics, also commonly referred to as behaviour genetics, is the field of study that examines the role of genetic and environmental influences on animal (including human) behaviour. Often associated with the ""nature versus nurture"" debate, behavioural genetics is highly interdisciplinary, involving contributions from biology, neuroscience, genetics, epigenetics, ethology, psychology, and statistics. Behavioural geneticists study the inheritance of behavioural traits. In humans, this information is often gathered through the use of the twin study or adoption study. In animal studies, breeding, transgenesis, and gene knockout techniques are common. Psychiatric genetics is a closely related field.
