Question 1
The heritability of IQ is about 0.5. This is interpreted by some to mean that IQ is 50 percent genetic and 50 percent environmental. Is this correct? What exactly does a heritability value of 0.5 mean?
Question 2
Using a large poster board, construct a Punnet Square involving three genes for skin color. One of the parents is completely dominant for all three genes and the other parent is completely recessive for all three genes. Then construct a graph of the number of offspring (y-axis) versus phenotype (skin color from lightest to darkest on the x-axis).
