Adoption study
A behaviour genetic research method that involves comparison of adopted children to their adoptive and biological parents.
Behavioural genetics
The empirical science of how genes and environments combine to generate behaviour.
Heritability coefficient
An easily misinterpreted statistical construct that purports to meaure the role of genetics in the explanation of differences among individuals.
Quantitative genetics
Scientific and mathematical methods for inferring genetic and environmental processes based on the degree of genetic and environmental similarity among organisms.
Twin studies
A behaviour genetic research method that involves comparison of the similarity of identical (monozygotic;MZ) and fraternal (dizygotic; DZ) twins.
Marilyn is a graduate student in psychology, and she has decided that she wants to study the influences of nature and nurture. Based on her goal of understanding the influences of nature and nurture, what is mostly likely the title of her research?
“How one’s genes interact with their surroundings to determine intelligence.”
The science of how one’s genetic code and their environmental influences interact to affect their actions is called ___.
Behavioural genetics.
Dr. Eplin is conducting a study with hundreds of children and the parents who raised them, but are not biologically related to the children. Dr. Eplin is curious whether genes or the household environment has a greater influence on children’s behaviour. What kind of study is Dr. Eplin conducting?
An adoption study.
When Paula and Paulette were first concieved, they were the result of a single fertilized egg splitting into two different zygotes. They share all of their genetic code, and can be thought of as natural clones. What kind of twins are they?
Monozygotic.
How much of their genetic code do fraternal twins share?
50%.
Martha and Mary are sisters who were born 2 1/2 years apart. Eric and Merrick are fraternal twin brothers who were born 8 minutes apart. Which of the following would be the most accurate statement regarding their genetic similarities?
The sisters are as genetically similar as the twin brothers.
As a general statement, the higher the ___ coefficient, the stronger the influence of one’s genes on a specific trait being examined.
Heritability.
Which of the following is a process in which the DNA itself is modified bu environmental events and those genetic changes are then transmitted to children?
Epigenetics.
