The threadlike coils of DNA 46- 23 from each parent |
|
|
What are genes? |
The biochemical units of heredity that make up chromosomes |
|
|
What is the human genome? |
The shared genetic profile that distinguishes humans from other species |
|
|
How do behavior geneticists explain our individual differences? |
They study the relative power and limits of genetic and environmental influences on behavior |
|
|
How do twin and adoption studies help us understand the effects and interactions of nature and nurture? |
-Separated identical twins maintain the same genes even if they grow up in different households -Shared family environments have little effect on personality |
|

|
|
How is molecular genetics research changing our understanding of the effects of nature and nurture? |
molecular genetics research is leading to new understanding in how teams of genes influence human traits -one goal is to figure out how genes interact in our environment and influence behavior |
|
|
What does the field of epigenetics study? |
The field of epigenetics studies the influences on gene expression that occur without changes in DNA |
