Chromosome
What does this represent?
DNA portion of the chromosome that carries _____
Each nucleus contains ______chromosomes; _______pairs.
This represents?
Alternative forms of a gene that produce different characteristics are called?
The particular characteristic a _______ trait controls will be displayed. The particular characteristic a _______trait controls will not be expressed, unless both parents have this trait.
A number of genes working together to create a specific phenotypic trait (i.e., appearance trait)
________ _________magnifies potential variation that can occur; the union of the sperm and egg can result in 70 trillion potential _______, even among siblings, although 99.9% of genes are identical among ________.
More understanding about our genome and our genes leads to better ______ discoveries
In 1990, the ______ _________occurred. In 2001, the ____ _____ was published.
The ____ ______ project wanted to map the specific human genome (the sum of a human's ______). They found out what?
And what does contemporary research allow us to do?
What exactly is the human genome?
This image represents?
The human genome
Represents?
The relationship between?
What does A represent?
Process of recombinant DNA procedures?
Genotype and phenotype are not identical because some genes are?

Hereditary & environment-->Psychology
______ _______ is a statistic that represents how much of a variation is heritable.
Heritability refers to? Heredity refers to?
WHAT IS THE DIFFERENCE BETWEEN PERCENT GENETICS VS ENVIRONMENT, AND AMT OF VARIATION?
I.E..., WHAT DOES 0.50 HERITABILITY COEFFICIENT MEAN>?
Heritability coefficients as they pertain to common human traits could be classed into three groups: action/performance, personality, and emotion .
What are common HC for "action/performance"?
HC pertaining to emotion?
HC relating to personality?
HC relating to quantifiable things: IQ, height, weight
The chromosome
________ is the likelihood that two people share a common characteristic.
When an adopted kid is compared to his/her adoptive AND biological parent(s) to indicate heredity.
A behaviour genetics method in which twins are compared; especially useful when they are raised in different places.
Twins can be ______ or ______.
Compare identical and fraternal twins on the basis of biology.
Heredity, hereditary, heritability
What do A and B represent?
Gene therapy and genetic counseling controversy
"researchers have inserted a gene associated with Alzhiemer's disease into the brain of mice and later tested the impact on neurotransmission, brain structure, and behaviour"
Genetic Screening and Therapy can be effective in...
Controversy/ arguments surrounding gene therapy and counseling
Good things about gene therapy
Good things about genetic counselling
Most useful research method in the field of behavioural genetics?
Reaction Range
An individual inherits a potential range of IQ at birth. The genetic component is not set in stone; what is actually expressed depends on the environment
Parents of little Johnny are very smart. This means his potential IQ range is high. However, where it falls in this potential IQ range depends on environmental factors,
Dyslexia
Environment and adoption programs account for how many IQ points?
Three levels of analysis in behavioural genetics?
What is the biological level of analysis?
What is the environmental level of analysis?
What is the psychological level of analysis?
Neural Plasticity/ brain plasticity
Review:
Receive information from the environment, process it, and then respond to it; based on the idea that humans are biological beings that actively respond to their environment and are self-regulating.
We begin life with innate _________ that enable us to take in, process, and respond to information, predisposing us to behave, feel, and even think in certain ways
"In humans, ____ _____ allow us to, among other things, learn, remember, speak a language, perceive certain aspects of our environment at birth, respond with universal emotions, and bond with other humans."
