Chapter 10 Student: _________________________________________________________ 1. Which of the following steps would NOT lead to variation of genetic material? A. crossing over of non-sister chromatids B. crossing over of sister chromatids C. the alignment of the chromosomes during metaphase I D. the combination of sperm and egg genes. 2. Which of the following is NOT a difference between anaphase I and anaphase II? A. Each chromosome is composed of two chromatids in anaphase I and only one chromatid in anaphase II. B. Anaphase I occurs in a haploid cell while anaphase II occurs in a diploid cell. C. Sister chromatids separate during anaphase II while homologous chromosomes separate during anaphase I. D. The cell undergoing anaphase II is genetically different from from what it contained while undergoing anaphase I. 3. It could be said that males are able to provide gametes with more genetic diversity than females for reproduction. One main reason would be: A. Males provide more genes in sperm than females provide in eggs. B. Crossing over occurs more often in the formation of sperm than in eggs. C. Spermatogenesis in males results in four functional sperm while oogenesis in females results in only one egg and three structures that contain genetic information that is lost when they disintegrate. D. Sperm that contain a recombination of genes are usually more successful in fertilizing an egg. 4. The cell formed through fertilization is called a/an A. gamete. B. sperm cell. C. zygote. D. egg cell. E. ovum. 5. If a sperm cell contains 8 chromosomes, it comes from an animal that has ______ chromosomes. A. 4 B. 8 C. 12 D. 16 E. 24 6. The term built from the Greek root words meaning "corresponding" or "agreeing" is A. tetrad. B. homologous. C. haploid. D. diploid. E. chromatid. 7. Another name for a tetrad is a/an A. homologue. B. bivalent. C. öocyte. D. gamete. E. polar body.

8. The term "bivalent" is built from the Latin root words meaning A. twice divided. B. two and strength. C. double genetic. D. half of a gene. E. joined together. 9. The term "synapsis" is built from the Greek root word meaning A. divided. B. two. C. summarized. D. gene. E. joined together. 10. If a cell contains 12 chromosomes at the end of meiosis I, how many chromosomes will the daughter cells contain at the end of meiosis II? A. 3 B. 6 C. 12 D. 24 11. During which stage of meiosis does crossing-over occur? A. prophase I B. anaphase I C. telophase I D. prophase II E. anaphase II 12. What is the importance of crossing-over? A. It provides extra genetic material for the daughter cells. B. It increases the likelihood that daughter cells contain different genetic material. C. It produces the proteins that are associated with DNA in chromosomes. D. It increases chromosome condensation.
