Normal mitotic cell division results in each daughter cell having

• half the number of chromosomes as the parent cell

• the same number and kinds of chromosomes as the parent cell

• the same number but different kinds of chromosomes as the parent cell

• twice the number of chromosomes as the parent cell

Which phrases best identify characteristics of asexual reproduction?

• one parent, union of gametes, offspring similar to but not genetically identical to the parent

• one parent, no union of gametes, offspring genetically identical to parents

• two parents, union of gametes, offspring similar to but not genetically identical to parents

• two parents, no union of gametes, offspring genetically identical to parents

Certain bacteria produce a chemical that makes them resistant to penicillin. Since these bacteria reproduce asexually, they usually produce offspring that

• can be destroyed by penicillin

• mutate into another species

• are genetically different from their parents

• survive exposure to penicillin

Which activity most directly involves the process represented in the diagram above?

• a gamete reproducing sexually

• a white blood cell engulfing bacteria

• a zygote being produced in an ovary

• an animal repairing damaged tissue

Strawberries can reproduce by means of runners, which are stems that grow horizontally along the ground. At the region of the runner that touches the ground, a new plant develops. The new plant is genetically identical to the parent because

• it was produced sexually

• nuclei traveled to the new plant through the runner to fertilize it

• it was produced asexually

• there were no other strawberry plants in the area to provide fertilization

What is the significance of anaphase in this process?

• Anaphase usually ensures that each daughter cell has the same number of chromosomes as the parent cell.

• Anaphase usually ensures that each daughter cell has twice as many chromosomes as the parent cell.

• In anaphase, the cell splits in half.

• In anaphase, the DNA is being replicated.
