DP1: Students must recognize the varied
influence of heredity and environment within a family. The power of
genetics is phenomenal, and though each cell only contains 23 pairs
of chromosomes, the possible manifestations of this hereditary
material are nearly limitless. Sayings such as “Blood is thicker
than water” indicate that we feel very close to our family members,
because we share inherited traits. However, we can’t ignore the
fact that we grow up in the same environment. To what extent does
the environment contribute to our similarities with our siblings?
Or does it? The challenge of identifying the relative influences of
nature and nurture is tremendous.
Describe the major traits you share with each of your siblings.
What major traits are very different for you and your siblings?
Which ones do you believe are biologically based, and which ones do
you think are the result of your environment? How do you explain
the differences, given you have the same parents and grew up in the
same family? If you are an only child, compare and contrast your
traits with those of each of your parents.
