In which phase of meiosis perform homologous chromosomes begin pairing?A. Prophase IB. Telophase IC. Metaphase ID. Anaphase IE. Metaphase II
A. Prophase ns Pairing of homologous chromosomes starts in prophase i of meiosis, and homologous chromosomes will continue to be paired until anaphase I.

You are watching: In which stage of meiosis do homologous chromosomes separate


During which step of meiosis perform homologous chromosomes separate?A. Prophase IB. Anaphase IIC. Metaphase IID. Metaphase IE. Anaphase I
E. Anaphase IHomologous chromosomes separate throughout anaphase I. Sisters chromatids separate during anaphase II.
During which phase of meiosis perform diploid cells first become haploid?A. Telophase IIB. Telophase IC. Prophase ID. Anaphase IE. Metaphase II
B. Telophase IWhen a cell completes meiosis I, during telophase I, the cell divides and also each daughter cell nucleus contains fifty percent the number of chromosomes that were present in the original cell that gotten in prophase I.
During which type of cell department does each daughter cabinet contain fifty percent the amount of DNA as did the cell just prior to cabinet division?A. Meiosis IB. Meiosis IIC. MitosisD. Meiosis I, meiosis II, and mitosisE. Meiosis I and meiosis II
D. Meiosis I, meiosis II, and mitosisThe amount of DNA is decreased by fifty percent in mitosis, meiosis I, and also in meiosis II.
If a typical diploid cell has actually 12 chromosomes, how numerous chromosomes are current in each daughter cell adhering to the conclusion that meiosis I?A. 6B. 12C. 24D. Much more than 12 yet fewer 보다 24E. None of the above.
A. 6During meiosis i a cabinet goes from being diploid to gift haploid. This needs the halving of the variety of chromosomes.
Within a provided species, i m sorry two varieties of cells have the equivalent quantities of DNA?A. A cell in G1 the interphase and also a cabinet in G2 the interphaseB. A cabinet in G1 the interphase and also a cell immediately after the perfect of meiosis IIC. A cell in G1 the interphase and also a cabinet in metaphase II of meiosisD. A cell in G2 the interphase and a cabinet in metaphase II the meiosisE. Nobody of the above.
C. A cabinet in G1 the interphase and also a cabinet in metaphase II of meiosisAlthough a cell in G1 of interphase will have actually twice the number of chromosomes together a cabinet in metaphase II, the amount of DNA will certainly be equivalent. For example, if a diploid cell had 12 chromosomes, a cabinet in G1 would have actually 12 chromosomes and also 12 DNA molecules. Likewise a cabinet in metaphase II would have actually six chromosomes, every consisting of 2 chromatids because that a complete of 12 DNA molecules.
If a cell typically has 12 chromosomes, how countless chromosomes are current in every cell throughout anaphase II?A. 6B. 12C. 24D. An ext than 12 but fewer than 24E. No one of the above
B. 12Although a cabinet entering meiosis II would have actually six chromosomes, each of these chromosomes would certainly consist of two double-stranded DNA molecules (sister chromatids). During anaphase, the sister chromatids separate resulting in 12 chromosomes till the perfect of telophase II once each daughter cabinet would have actually six chromosomes, each consisting that a single DNA molecule.
During which phase of meiosis do homologous chromosome pairs heat up ~ above the metaphase plate?A. Metaphase IIB. Metaphase IC. Anaphase ID. Anaphase IIE. Prophase I
B. Metaphase IHomologous chromosome pairs, that very first joined in prophase I, line up top top the metaphase key in metaphase I. This chromosome pairs separate during anaphase I, conversely, chromosomes line up on the metaphase key individually throughout metaphase II, and also centromeres authorized sister chromatids division creating brand-new chromosomes during anaphase II.
Meiosis II is often taken into consideration to be comparable to mitosis. Which of the following functions is mutual by both meiosis II and mitosis?A. Both mitosis and meiosis II immediately follow one interphase wherein DNA was replicated.B. Within a provided species, a cabinet entering mitosis or meiosis II will have equivalent number of chromosomes.C. Individual chromosomes align ~ above the metaphase plate and also sister chromatids different at anaphase in both mitosis and also meiosis II.D. In ~ a provided species, a cell entering mitosis or meiosis II will have equivalent amounts of DNA.E. Every one of the above features room common in between mitosis and also meiosis II.
C. Separation, personal, instance chromosomes align top top the metaphase plate and also sister chromatids separate at anaphase in both mitosis and also meiosis II.DNA is not replicated in between meiosis I and meiosis II. Also, due to the fact that a cell entering meiosis II is haploid, the variety of chromosomes in a cell entering meiosis II is fifty percent the number in a cell entering mitosis. Also, a cabinet entering meiosis II will contain fifty percent the quantity of DNA contrasted to a cabinet entering mitosis. Therefore, the only correct prize is "C" due to the fact that individual chromosomes line up top top the metaphase plate in both mitosis and also meiosis II.
If a cell normally has 12 chromosomes, how numerous chromosomes would be current in every cell in ~ the end of meiosis II if a single pair of homologous chromosomes failed to separate during anaphase I?A. Two daughter cells will certainly each have six chromosomes, one daughter cell will have 5 chromosomes, and one daughter cabinet will have seven chromosomes.B. Two daughter cells will certainly each have six chromosomes and two daughter cells will each have seven chromosomes.C. All four daughter cell will have six chromosomes.D. Two daughter cells will certainly each have 5 chromosomes and also two daughter cells will each have actually seven chromosomes.E. All 4 daughter cells will certainly have 5 chromosomes.

D. Two daughter cells will certainly each have five chromosomes and two daughter cells will certainly each have seven chromosomes.If a solitary pair the homologous chromosomes failed to separate in anaphase I, one of the daughter cells would certainly inherit an extra chromosome (seven chromosomes), and also the various other daughter cell would be absent a chromosome (five chromosomes). As each of this initial two daughter cells entered meiosis II, the sister chromatids would separate generally in anaphase II causing two cells having actually seven chromosomes and two cells having five chromosomes at the end of meiosis.
