A karyotype is shown. Information in this karyotype indicates that the individual is a:
male with Tay-Sachs disease.
female with Sickle Cell Anemia.
male with Phenylkentonuria.
female with Down Syndrome.
Identical twins were separated at birth and raised by different families. The best explanation for any differences between the twins in height, weight, and IQ scores is that the genes regulating these traits were:
linked.
environmentally influenced.
independently assorted.
codominant.
