A scientist is preparing a lecture for a symposium next week on the topic of cloning. If he agrees with most current scientists, what will he most likely say in his lecture?
a. Scientists do not yet have the capability to perform reproductive cloning of human beings.
b. Because of the low mortality rate during the cloning of other mammals, scientists overwhelmingly support research into reproductive cloning of humans.
c. Reproductive cloning of humans is more successful than the cloning of other mammals, but genetic glitches pose ethical problems.
d. Because there are so many unknowns, most scientists consider human reproductive cloning to be potentially dangerous and ethically irresponsible.
Question 2
A zygote forms from reproductive cells. How does the zygote then transform into cells that perform all of the functions in the human body?
a. DNA controls cell differentiation for various functions.
b. Genes guide cell differentiation for unique functions.
c. Dominant-recessive inheritance transforms cells for diverse functions.
d. Co-dominant factors transform cells for diverse functions.
