Both are involved in asexual reproduction.
- B.
Both occur only in reproductive cells.
- C.
The number of chromosomes is reduced by half.
- D.
DNA replication occurs before the division of the nucleus.
- 5.A cell resulting from the fertilization of an egg begins to divide. Two cells are formed that normally remain attached and could develop into a new individual. If the two cells become separated, which statement describes what would most likely occur?
- A.
The cells would each have all of the needed genetic information, and both could survive.
- B.
The cells would each have only one-half of the needed genetic information, so both would die.
- C.
One cell would have all of the needed genetic information and would survive, but the other would have none of the needed genetic information and would die.
- D.
One cell would have all of the needed genetic information and would survive, but the other would have none of the needed genetic information and would die.
- 6.Although all of the cells of a human develop from one fertilized egg, the human is born with many different types of cells. Which statement best explains this observation?
- A.
All cells have different genetic material.
- B.
Mutations occur during development as a result of environmental conditions.
- C.
Developing cells may express different parts of their identical genetic instructions.
- D.
Some cells develop before other cells.
- 7.Tissues develop from a zygote as a direct result of the processes of
- A.
Fertilization and meiosis
- B.
Fertilization and differentiation
- C.
Mitosis and meiosis
- D.

- B.
Cells 1 and 2
- C.
Cell 3, only
- D.
Cells 2 and 3
- 9.Which statement concerning the reproductive cells in the diagram below is correct?
- A.
The cells are produced by mitosis and contain all the genetic information of the father.
- B.
If one of these cells fertilizes an egg, the offspring will be identical to the father.
- C.
Each of these cells contains only half the genetic information necessary for the formation of an offspring.
- D.
An egg fertilized by one of these cells will develop into a female with the same characteristics as the mother.
- 10.The development of an embryo is represented in the diagram below. These changes in the form of the embryo are a direct result of
- A.
Uncontrolled cell division and mutations
- B.
Differentiation and growth
- C.
Antibodies and antigens inherited from the father
- D.
Meiosis and fertilization

- A.
Why some offspring are genetically identical to their parents
- B.
The process of differentiation in offspring
- C.
Why some offspring physically resemble their parents
- D.
The origin of new combinations of traits in offspring
- 12.Which statement best explains the observation that clones produced from the same organism may not be identical?
- A.
Events in meiosis result in variation.
- B.
Gene expression can be influenced by the environment.
- C.
Differentiated cells have different genes.
- D.
Half the genetic information in offspring comes from each parent.
- 13.The diagram below represents a nucleus containing the normal chromosome number for a species. Which diagram bests illustrates the normal formation of a cell that contains all of the genetic information needed for growth, development, and future reproduction of this species?
