Which type of explanation describes why a structure or behavior evolved as it did?
Functional Explanation
What is the main function of RNA in relation to protein synthesis?
To serve as a model for synthesis of proteins
What is the primary difference between autosomal genes and sex-linked genes?
Autosomal genes are found on autosomes, while sex-linked genes are found on sex chromosomes
What is the term for the change in a single gene that is rare, random, and independent of the needs of the organism?
Mutation
What is the role of histones in the nucleus?
To condense chromatin into chromosomes
What is the study of how behaviors and environment can cause changes that affect the way genes work?
Epigenetics
Why do genes come in pairs?
Because they are aligned along chromosomes
What is the primary purpose of life from a biological perspective?
To procreate
How can a gene influence behavior even if it is not expressed in the brain?
By producing a protein that interacts with the environment
What is the primary function of heredity in the development of an individual's behavior?
To create a framework for the environment to act upon
What is the key to giving an evolutionary explanation of a behavior?
Explaining how the behavior helps us to survive and/or procreate
What is the term for the measure of how well genetic differences account for differences in a particular trait?
Heritability
What is the result of behavior that helps us to survive and/or procreate?
The genes that influence the behavior are passed on to offspring

MZ twins are identical, while DZ twins are fraternal
What is the role of genes in learning and memory?
Genes create a framework for learning and memory
What is the cycle of behavior and evolution?
Behavior > Helps procreation > Genes passed on > Biology that helps behavior is also passed on > Offspring shows same behavior
What is phenylketonuria (PKU)?
An inherited disorder that affects the level of phenylalanine in the blood
How can the environment affect an individual's behavior?
By shaping the morphological and physiological development of the individual
