To learn more, read your instructor's Grading Policy Description: (a) Asexual reproduction. Chapter 13 Pre-Test Question 1 Asexual reproduction. The prefix "a-" means "without." requires both meiosis and mitosis produces offspring genetically identical to the parent is limited to single-cell organisms is limited to plants leads to a loss of genetic material Only one individual makes a genetic contribution to the offspring. Chapter 13 Pre-Test Question 2 Description: (a) What number and types of chromosomes are found in a human somatic cell? What number and types of chromosomes are found in a human somatic cell? Somatic cells are diploid. 44 autosomes and 2 sex chromosomes 22 autosomes and 1 sex chromosome 45 autosomes and 1 sex chromosome n chromosomes 21 autosomes and 2 sex chromosomes 1 von :06

2 Human somatic cells contain 22 pairs of autosomes and either two X chromosomes (in females) or an X and a Y chromosome (in males). Chapter 13 Question 3 Description: [[Bloom's Taxonomy: Knowledge/Comprehension ]] (a) Which of the following defines a genome? Which of the following defines a genome? a karyotype representation of a complete set of a cell's polypeptides the complete set of an organism's genes the complete set of a species' polypeptides the complete set of an organism's polypeptides Chapter 13 Pre-Test Question 5 Description: (a) How are sister chromatids and homologous chromosomes different from each other? How are sister chromatids and homologous chromosomes different from each other? Which type of chromosomes are identical copies and which are similar? They are not different. Homologous chromosomes and sister chromatids are both identical copies of each other. Homologous chromosomes contain the same gene loci but may have different alleles of a particular gene. Sister chromatids are identical copies of each other produced during DNA replication. Homologous chromosomes are identical copies of each other. One sister chromatid comes from the father, and one comes from the mother. Homologous chromosomes are closely associated with each other in both mitosis and meiosis. Sister chromatids are only associated with each other during mitosis. Sister chromatids are only formed during mitosis. Homologous chromosomes are formed during meiosis. 2 von :06

3 One homologous chromosome comes from the father, and the other comes from the mother. Sister chromatids are identical copies of each other. Chapter 13 Question 2 Description: [[Bloom's Taxonomy: Knowledge/Comprehension ]] (a) Which of the following is a true statement about sexual vs. asexual reproduction? Which of the following is a true statement about sexual vs. asexual reproduction? Asexual reproduction, but not sexual reproduction, is characteristic of plants and fungi. In sexual reproduction, individuals transmit 50% of their genes to each of their offspring. In asexual reproduction, offspring are produced by fertilization without meiosis. Sexual reproduction requires that parents be diploid. Asexual reproduction produces only haploid offspring. Chapter 13 Question 6 Description: [[Bloom's Taxonomy: Knowledge/Comprehension ]] (a) Eukaryotic sexual life cycles show tremendous variation.

In humans, the 23rd pair, the sex chromosomes, determines whether the person is female (XX) or male (XY). At sexual maturity, ovaries and testes produce diploid gametes by meiosis. Sexual life cycles differ with respect to the relative timing of meiosis and fertilization. Single, haploid (n) sets of chromosomes in ovum and sperm unite during fertilization, forming a diploid (2n), single-celled zygote.

10 Look at the cell in the figure. Based on this figure, which of the following statements is true? This cell is diploid. It is impossible to tell whether the cell is haploid or diploid. This cell is haploid. This is correct. Read Concept 13.2 and continue to Question 3, below. Chapter 13 Misconception Question 3 What is the best evidence telling you whether this cell is diploid or haploid? 10 von :06

11 The cell is diploid because each chromosome consists of two chromatids. The cell is diploid because it contains two sets of chromosomes. The cell is haploid because the chromosomes are not found in pairs. Correct! Only diploid cells contain two sets of chromosomes, one maternal and one paternal. Read about diploid cells in Concept Chapter 13 Misconception Question 4 This chromosome has two chromatids, joined at the centromere. What process led to the formation of the two chromatids? The two chromatids were formed by fertilization, bringing together maternal and paternal chromatids. The two chromatids were formed by synapsis and the formation of a synaptonemal complex. The two chromatids were formed by replication of the DNA within a single chromatid. Correct! Read Concept Chapter 13 Misconception Question 5 11 von :06

12 Two sister chromatids are joined at the centromere prior to meiosis. Which statement is correct? The cell that contains these sister chromatids must be diploid. These chromatids make up a diploid chromosome. Barring mutation, the two sister chromatids must be identical. Yes, this is correct. Unless there are replication errors known as mutations, DNA replication and chromosome duplication produce a chromosome consisting of two genetically identical chromatids.
