threadlike structures made of DNA molecules that contain the genes.
): a complex molecule containing genetic information that makes up the chromosomes.
: the biochemical units of heredity that make up chromosomes, a segment of DNA capable of synthesizing a protein
: the study of the relative power and limits of genetic and environmental influences on behavior.
every no genetic influence, from prenatal nutrition to the people and things around us.
: twins who developed from single zygote that splits into two.
: twins who develop from separate eggs. Genetically no closer than brothers and sisters but share a fetal environment
the effect of one factor (such as environment) depends on another factor (such as heredity)
the subfield of biology that studies the molecular structure and function of genes.
the complete instructions for making an organism, consisting of all the genetic material in its chromosomes. (blue print)
An organism's physical appearance, or visible traits
The combination of genes for one or more specific traits
the proportion of phenotypic variation (difference) in a population attributable to genetic factors
a discussion of how genes and the environment interact and how genes change to fit the environment; how traits that have led to survival are more likely to be passed down
the process by which individuals that are better adapted to their environment survive and reproduce more successfully than less well adapted individuals do
Certain biological and behavioral variations increase organisms' reproductive and survival chances in their particular environment
