What is your answer?

The following is NOT a reason for the need to develop satisfactory therapies for gene defects.

    { 1 } - Parent carriers of defective genes may have as much as a 50 percent risk of generating offspring with a genetic defect.
    { 2 } - Approximately 3000 different diseases are known to involve single defective genes.
    { 3 } - 33 percent of infant deaths are related to genetic causes.
    { 4 } - 100 genetic conditions can be diganosed prenatally.
    { 5 } - 20 percent of children are born with life threatening genetic diseases.

5 is correct!

The following is NOT a reason for the need to develop satisfactory therapies for gene defects.

    { 1 } - Parent carriers of defective genes may have as much as a 50 percent risk of generating offspring with a genetic defect.
    { 2 } - Approximately 3000 different diseases are known to involve single defective genes.
    { 3 } - 33 percent of infant deaths are related to genetic causes.
    { 4 } - 100 genetic conditions can be diganosed prenatally.
    { 5 } - 20 percent of children are born with life threatening genetic diseases.

There seems to be approximately a 5 percent incidence of genetic disease in all live births. See p. 249.
