Reproduction and Development Test Review

When an organism reproduces asexually, it usually has

• only one parent, half as much DNA as the parent

• only one parent, and the same chromosome number as the parent

• two parents, and twice as much DNA as either parent

• two parents, and the same chromosome number as each parent

Which process allows a mammal to continue to grow in size?

• mitosis of sex cells

• mitosis of body cells

• meiosis of sex cells

• meiosis of body cells

Asexual reproduction primarily involves the process of

• ovulation

• pollination

• mitosis

• spermatogenesis

The process of mitotic cell division normally results in the production of

• four cells with half the number of chromosomes as the parent cell

• two cells with the same number of chromosomes as the parent cell

• two cells with only one chromosome from each set of homologous chromosomes

• one cell with a replicated set of homologous chromosomes

Strawberries can reproduce by means of runners, which are stems that grow horizontally along the ground. Why is the new plant genetically identical to the parent?

• it was produced sexually

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

• it was produced asexually

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

Offspring that result from fertilization each have

• twice as many chromosomes as their parents

• one-half as many chromosomes as their parents

• gene combinations different from those of either parent

• gene combinations identical to those of each parent

Which cell process occurs only in organisms that reproduce sexually?

• mutation

• replication

• meiosis

• mitosis

How do human cells resulting from meitoic division differ from human cells resulting from mitotic division?

• they have twice as many chromosomes

• they have the same number of chromosomes

• they have one-half the number of chromosomes

• they have one-quarter as many chromosomes

Essential materials needed for development are transported to a human fetus through the

• reproductive hormones

• egg cell

• placenta

• ovaries

In the human female reproductive system, the union of sperm and ovum normally takes place within the

• ovary

• vagina

• uterus

• oviduct
