The small segments of Dna that contain information for producing proteins?
Different forms of a gene
The genes that show their effect even if there is only one allele for that trait in the pair
Genes that show their effects only when both alleles are the same.
The scientific study of the role of heredity in behavior
The hereditary passing on of traits determined by a single gene
The process by which many genes interact to create a single characteristic
The extent to which a characteristic is influenced by genetics
Twins that develop from two differnt eggs fertilized by two different sperm
Twins that develop from a songle fertilized egg that splits into two independent cells
Research into hereditary influnce on twins, both identical and fraternal, who were raised apart and who were raised together
Method of studying heritability by comparing genetic markers
Gene-by-enviroment interaction research
The entire genetic make up of an organism
Study of changes in the way genes are turned on or off without a change in the DNA sequence
THe organisms observed characteristics
genes occur in pairs, or alternate forms of each other, called
Why are twin-adaoptions studies powerful ways to untangle the effects of genes and enviroment on thought and behavior?
a. because they allow both genetic and enviromental similarity to be compared and contrasted
b. because twins share genes
c. because of epigenetics
d. because they allow researchers to experimentally manipulate genetic and environmental similarity
Nurturing behavior in rats can produce, calmer, less stressed offspring because genes that are involved in stress reactions are tuned off. This is an example of
b. genetic engineering
d. dominant genes
