Identical twins
twins who develop from a single fertilized egg that splits in two, creating two genetically identical organisms
fraternal twins
twins who develop from separate fertilized eggs. they are genetically no closer than brothers and sisters, but they share a fetal environment
the proportion of variation among individuals that we can attribute to genes. this may vary, depending on the range of populations and environments studied
the interplay that occurs when the effect of one factor depends on another factor
molecular genetics
the subfield of biology that studies the molecular structure and function of genes
evolutionary psychology
the study of the roots of behavior and mental processes using the principles of natural selection
natural selection
the principle that, among the range of inherited trait variations, those contributing to reproduction and survival will most likely be passed on to succeeding generations
a random error in gene replication that leads to a change
one major criticism of the evolutionary perspective in psychology
it analyzes after the fact using hindsight
evolutionary psychologists seek to understand how traits and behavioral tendencies have been shaped by
natural selection

thomas bouchard’s study of twins is notable, because

men are attracted to women who appear fertile and capable of bearing children
which of the following is as example of a phenomenon that could be explained by natural selection
women tend to seek men who can provide protection for their children because this has increased the survival rate of children in the past
when the mother’s egg and the father’s sperm unite, each contributes
23 chromosomes
researchers find the study of fraternal twins important because,
they are the same age and are usually raised in similar environments, but they do not have the same genetic code
heritability refers to the percentage of
group variation in a trait that can be explained by genetics
threadlike structures made of dna molecules that contain the genes are called
the study of specific genes and teams of genes that influence behavior is called
molecular genetics
the interplay of environment and heredity is called
in an effort to reveal genetic influences on personality, researchers use adoption studies mainly to
evaluate whether adopted children more closely resemble their adoptive parent or their biological parents
