Genes correct answers The basic units of heredity; genes are responsible for guiding the process
of creating the proteins that make up our physical structures and regulate development and
physiology processes throughout the lifespan
DNA correct answers is a molecule formed in a double-helix shape that contains four
nucleotides; adenine, cytosine, guanine, thymine
Genotype correct answers the genetic makeup of an organism. The unique set of genes that
comprise that individuals genetic code
Phenotype correct answers the physical traits and behavioural characteristics that show genetic
variation such as eye colour, the shape and size of facial features, intelligence and even
personality
Chromosomes correct answers Structures in the cellular nucleus that are lined with all of the
genes an individual inherits
Homozygous correct answers two genes on a pair of chromosomes are the same
Heterozygous correct answers if two genes differ
Tasters of PTC correct answers TT or Tt
non Tasters of PTC correct answers tt
behavioural genomics correct answers the study of DNA and the ways in which specific genes
are related to behaviour
Behavioural genetics correct answers the study of how genes and the environment influence
behaviour
Monozygotic twins correct answers come from a single ovum (egg), which makes them
genetically identical (almost 100% genetic similarity)
Dizygotic twins correct answers (fraternal twins) come from two separate eggs fertilized by two
different sperm cells that share the same womb. These twins have approximately 50% of their
genetics in common
Longitudinal studies correct answers studies that follow the same individuals for many years,
often decades
Heritability correct answers a statistic, expressed as a number between zero and one, that
represents the degree to which genetic differences between individuals individuals contribute to
individual differences in a behaviour or trait found in population
, Epigenetics correct answers Changes in gene expression that occur as a result of experience and
that do not alter the genetic code
Natural selection correct answers the process by which favourable traits become increasingly
common in a population of interbreeding individuals, while traits that are unfavourable become
less common
Evolution correct answers the change in the frequency of genes occurring in an interbreeding
population over generations
Evolutionary psychology correct answers attempts to explain human behaviours based on the
beneficial functions they may have served in our species development
Intrasexual selection correct answers a situation in which members of the same sex compete in
order to win the opportunity to mate with members of opposite sex
Intersexual selection correct answers a situation in which members of one sex select a mating
partner based on their desirable traits
Neurons correct answers one of the major types of cells found in the nervous system, that are
responsible for sending and receiving messages throughout the body
cell body correct answers also known as soma, the part of a neuron that contain the nucleus that
houses the cell's genetic material
Dendrites correct answers small branches radiating from the cell body that receive messages
from other cells and transmit those messages toward the rest of the cell
Axon correct answers transports information in the form of electrochemical reactions from the
cell body to the end of the neuron
Axon terminals correct answers bulb like extensions filled with vesicles
Neurotransmitters correct answers the chemicals that function as messengers allowing neurons to
communicate with each other
Sensory neurons correct answers receive information from the bodily senses and bring it toward
the brain, often through the spinal cord
Motor neurons correct answers carry messages away from the brain and spinal cord and toward
muscles in order to control their flexion and extensions
Neurogenesis correct answers the formation of new neurons in a limited number of brain regions,
particularly in a region critical for learning and memory
