A) Homologous chromosomes

Which of the following statements regarding mitosis and meiosis is true? A) Sister chromatids separate during anaphase of mitosis and anaphase II of meiosis. B) Mitosis takes place in your gametes, whereas meiosis takes place in your somatic cells. C) In metaphase of mitosis and metaphase I of meiosis, homologous chromosomes separate. D) Independent orientation occurs during metaphase of mitosis and metaphase II of meiosis.

A) Sister chromatids separate during anaphase of mitosis and anaphase II of meiosis.

Homologous chromosomes ______. A) carry genes controlling the same inherited characteristics B) include only the autosomes C) are a set of chromosomes that the cell received from one parent D) carry the same versions of all genes

In meiosis, how does prophase I differ from prophase II? A) During prophase I there is one diploid cell; during prophase II there are two haploid cells. B) During prophase I chromosomes line up single file in the middle of the cell; during prophase II the chromosomes line up in double file in the middle of the cell. C) During prophase I the chromosomes coil up; the chromosomes are not coiled up during prophase II. D) In prophase I the sister chromatids are attached; in prophase II the sister chromatids are separated.

C) During prophase I the chromosomes coil up; the chromosomes are not coiled up during prophase II.

Which of the following is the best description of the events of anaphase I?

B) Sister chromatids separate and the daughter chromosomes migrate to opposite poles. C) Homologous chromosomes randomly separate and migrate to opposite poles. D) All of the chromosomes inherited from the mother go to one pole of the cell, and all of the chromosomes inherited from the father go to the other pole

C) Homologous chromosomes randomly separate and migrate to opposite poles.

When does crossing over occur? A) Cytokinesis B) Mitosis C) Meiosis I D) Meiosis II
