What is the order for genes? |
Genes, DNA, Chromosomes |
|
|
How many chromosomes do we have? |
46 (23 from dad, 23 from mom) |
|
|
Behavior genetics |
The study of the relative power and limits of genetic and environmental influences on behavior |
|
|
Environment |
Every non-genetic influence, from prenatal nutrition to the people and things around us |
|
|
Chromosomes |
Threadlike structures made of DNA molecules that contain the genes |
|
|
DNA |
A complex molecule containing the genetic information that makes up the chromosomes |
|
|
Genes |
The biochemical units of heredity that make up the chromosomes, segments of DNA capable of synthesizing a protein |
|
|
Genome |
The complete instructions for making an organism, consisting of all the genetic material in that organisms chromosomes |
|
|
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 |
|
|
Heritability |
The proportion of variation among individuals that we can attribute to genes. The heritability of a trait may vary, depending on the range of populations and environments studied |
|
|
Interaction |
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 evolution of behavior and the mind, using principles of natural selection |
|
|
Natural Selection |
The principle that, among the range of inherited trait variation, those that lead to increased reproduction and survival will most likely be passed on to succeeding generations |
|
|
Mutation |
A random error in gene replication that leads to a change |
|
|
What percentage of genetic variation is there within populations? |
95% |
|
|
Where is DNA found? |
In all your cells |
|
|
Anecdotal evidence |
non-scientific observations or studies, which do not provide proof but may assist research efforts |
|
|
Virtual Twins |
Two different people with many things in common |
|
|
Imprinting |
Latching on to the first thing you see (Twilight) |
