A. Prophase ns Pairing the homologous chromosomes begins in prophase i of meiosis, and homologous chromosomes will continue to be paired till anaphase I.
You are watching: During which phase of meiosis do homologous chromosomes separate
During which step of meiosis carry out homologous chromosomes separate?A. Prophase IB. Anaphase IIC. Metaphase IID. Metaphase IE. Anaphase I
E. Anaphase IHomologous chromosomes separate during anaphase I. Sisters chromatids separate during anaphase II.
During which step of meiosis carry out diploid cells first become haploid?A. Telophase IIB. Telophase IC. Prophase ID. Anaphase IE. Metaphase II
B. Telophase IWhen a cabinet completes meiosis I, during telophase I, the cabinet divides and also each daughter cabinet nucleus contains fifty percent the variety of chromosomes the were existing in the initial cell that entered prophase I.
During which kind of cell department does every daughter cabinet contain half the quantity of DNA as did the cell simply prior to cell division?A. Meiosis IB. Meiosis IIC. MitosisD. Meiosis I, meiosis II, and also mitosisE. Meiosis I and meiosis II
D. Meiosis I, meiosis II, and also mitosisThe lot of DNA is diminished by half in mitosis, meiosis I, and also in meiosis II.
If a common diploid cell has actually 12 chromosomes, how countless chromosomes are present in each daughter cell adhering to the conclusion that meiosis I?A. 6B. 12C. 24D. More than 12 yet fewer 보다 24E. No one of the above.
A. 6During meiosis ns a cell goes from being diploid to being haploid. This needs the halving that the variety of chromosomes.
Within a given species, i m sorry two varieties of cells have the equivalent quantities of DNA?A. A cabinet in G1 the interphase and also a cell in G2 the interphaseB. A cell in G1 the interphase and a cell instantly after the perfect of meiosis IIC. A cell in G1 that interphase and also a cell in metaphase II of meiosisD. A cabinet in G2 that interphase and a cell in metaphase II that meiosisE. Nobody of the above.
C. A cabinet in G1 the interphase and a cabinet in metaphase II of meiosisAlthough a cell in G1 the interphase will have actually twice the number of chromosomes together a cell in metaphase II, the lot of DNA will be equivalent. Because that example, if a diploid cell had actually 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, each consisting of two chromatids for a total of 12 DNA molecules.
If a cell usually has 12 chromosomes, how many chromosomes are present in every cell throughout anaphase II?A. 6B. 12C. 24D. Much more than 12 yet fewer 보다 24E. None of the above
B. 12Although a cell entering meiosis II would have actually six chromosomes, each of these chromosomes would consist of 2 double-stranded DNA molecule (sister chromatids). Throughout anaphase, the sister chromatids separate causing 12 chromosomes till the perfect of telophase II once each daughter cabinet would have actually six chromosomes, every consisting the a solitary DNA molecule.
During which phase of meiosis perform homologous chromosome pairs heat up on the metaphase plate?A. Metaphase IIB. Metaphase IC. Anaphase ID. Anaphase IIE. Prophase I
B. Metaphase IHomologous chromosome pairs, that an initial joined in prophase I, heat up top top the metaphase key in metaphase I. This chromosome pairs separate throughout anaphase I, vice versa, chromosomes line up top top the metaphase plate individually throughout metaphase II, and also centromeres joining sister chromatids divide creating new chromosomes throughout anaphase II.
Meiosis II is often considered to be comparable to mitosis. Which of the following attributes is common by both meiosis II and mitosis?A. Both mitosis and meiosis II automatically follow an interphase whereby DNA was replicated.B. Within a offered species, a cabinet entering mitosis or meiosis II will have actually equivalent number of chromosomes.C. Individual chromosomes align ~ above the metaphase plate and sister chromatids separate at anaphase in both mitosis and meiosis II.D. In ~ a provided species, a cell entering mitosis or meiosis II will have actually equivalent amounts of DNA.E. Every one of the above features room common between mitosis and meiosis II.
C. Separation, personal, instance chromosomes align ~ above the metaphase plate and sister chromatids different at anaphase in both mitosis and also meiosis II.DNA is not replicated between meiosis I and also meiosis II. Also, since a cell entering meiosis II is haploid, the number 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 half the quantity of DNA contrasted to a cabinet entering mitosis. Therefore, the only correct price is "C" because individual chromosomes heat up ~ above the metaphase bowl in both mitosis and meiosis II.
If a cell usually has 12 chromosomes, how countless chromosomes would be current in each cell at the end of meiosis II if a solitary pair of homologous chromosomes failed come separate during anaphase I?A. 2 daughter cells will certainly each have six chromosomes, one daughter cell will certainly have 5 chromosomes, and also one daughter cell will have seven chromosomes.B. 2 daughter cells will each have actually six chromosomes and two daughter cells will certainly each have actually seven chromosomes.C. All 4 daughter cell will have actually six chromosomes.D. 2 daughter cells will certainly each have five chromosomes and also two daughter cells will each have actually seven chromosomes.E. All four daughter cells will have 5 chromosomes.

D. Two daughter cells will each have 5 chromosomes and two daughter cells will certainly each have seven chromosomes.If a single pair of homologous chromosomes failure to separate in anaphase I, one of the daughter cells would certainly inherit one extra chromosome (seven chromosomes), and also the other daughter cell would certainly be missing a chromosome (five chromosomes). Together each of this initial 2 daughter cells entered meiosis II, the sisters chromatids would certainly separate usually in anaphase II causing two cells having actually seven chromosomes and also two cell having 5 chromosomes in ~ the end of meiosis.
