4. Cell Division 1.What is the result of the fertilization of an egg?
It restores the diploid number of chromosomes
It deletes polypeptide chains in the chromosomes
It gives offspring more chromosomes than the parents
It gives offspring fewer chromosomes than the parents

5. Cell Division
2.Which statement best describes an advantage of asexual reproduction for a population of organisms?
The population can increase in number more rapidly
The population can develop greater genetic diversity
The population can maintain the same number of organisms
The population can adapt more quickly to a changing environment

6. Cell Division
3.How many daughter cells are formed in meiosis? 1 2 4

7. Cell Division
4.Two gametes containing 20 chromosomes fuse during fertilization. How many chromosomes will the zygote cell contain? 10 20 40 80

8. Cell Division
5.A cell with 24 chromosomes undergoes mitosis twice. How many chromosome will each daughter cell have? 6 12 24 48

9. Cell Division
6.Before mitosis begins, which happens before the nucleus starts dividing?
The cytoplasm separates
The DNA replicates
The sister chromatids separate
The homologous chromosomes cross over

10. Cell Division 7.Why is meiosis important for sexual reproduction?
It allows the zygote formed from fertilization to have triple the chromosome number of the organism
It allows gametes to have twice the original number of chromosomes of the organism
It allows gametes to have half the original number of chromosomes of the organism
It allows the zygote formed from fertilization to have half the original number of chromosomes of the organism

11. Cell Division
8.What is the result when a single cell reproduces by mitosis?
Two cells with genetic material identical to the parent cell
Two cells with half the genetic material of he parent cell
Four cells with half the genetic material of the parent cell
Four cells with genetic material identical to the parent cell

12. Cell Division
9.Which characteristic is present in offspring produced by sexual reproduction, but is missing in offspring produced by asexual reproduction?
An identical copy of parent chromosomes
Twice the number of parent chromosomes
Only half the number of parent chromosomes
An independent assortment of parent chromosomes

13. Cell Division
10.Which term describes the failure of homologous chromosomes to segregate properly during meiosis?
Polyploidy
Recombination
Nondisjunction
Independent assortment

14. Cell Division
11.Which statement correctly describes the number of chromosomes in body cells and gametes?
Body cells and gametes are both diploid
Body cells and gametes are both haploid
Body cells are diploid and gametes are haploid
Body cells are haploid and gametes are diploid

15. Cell Division
12.How are sexual reproduction and asexual reproduction different?
Sexual reproduction produces offspring identical to the parents, but asexual reproduction produces offspring with traits from both parents.
Asexual reproduction produces offspring identical to the parents, but sexual reproduction produces offspring with traits from both parents.
Sexual reproduction only occurs in multicellular organisms, but asexual reproduction only occurs in unicellular organisms.
Asexual reproduction only occurs in multicellular organisms, but sexual reproduction only occurs in unicellular organisms.
