You asked: Which of the following does not occur during meiosis one?

Which of the following events does not occur in meiosis 1?

Option C is the answer. Crossing over of nonsister chromatids of the homologous chromosomes happens during pachytene stage of meiosis I.In the option it is given crossing over of sister chromatids which is wrong.

Which of the following occurs during meiosis 1?

Meiosis I & II

In meiosis I, chromosomes in a diploid cell resegregate, producing four haploid daughter cells. It is this step in meiosis that generates genetic diversity. DNA replication precedes the start of meiosis I. During prophase I, homologous chromosomes pair and form synapses, a step unique to meiosis.

Which does not occur during meiosis?

In meiosis , synapsis ( Pairing of homologous chromosome ) , Crossing over ( exchange of chromosomal segment between nos sister chromatids ) occurs which does not occur in mitosis.

Which of the following does not occur during prophase 1 of meiosis?

E) Homologous pairs of chromosomes align at the metaphase plate does not occur during prophase I of meiosis.

Which of the following events occur during anaphase 1?

In anaphase I, centromeres break down and homologous chromosomes separate. In telophase I, chromosomes move to opposite poles; during cytokinesis the cell separates into two haploid cells.

Which one of the following does not occur during anaphase?

During anaphase, sister chromatids will separate and begin to move toward opposite poles of the cell. At this stage, DNA will not replicate any further (replication occurs only in interphase). Therefore, the correct answer is b. The chromatid DNA replicates.

Which of the following occurs during meiosis 1 but not during mitosis?

(d) Synapsis occurs during meiosis but not during mitosis during mitosis.

Which of the following occurs during meiosis one but not during mitosis?

Explanation: Crossing over is the only answer choice that does not occur during mitosis. Crossing over occurs during prophase I of meiosis and involves swapping of genetic information between homologous chromosomes. This require the formation of tetrads, which does not occur during mitosis.

Which event occurs during meiosis 2 but not during meiosis 1?

In meiosis II, these chromosomes are further separated into sister chromatids. Meiosis I includes crossing over or recombination of genetic material between chromosome pairs, while meiosis II does not.

Which does not occur during meiosis II?

Meiosis II begins with the 2 haploid cells where each chromosome is made up of two connected sister chromatids. DNA replication does NOT occur at the beginning of meiosis II. The sister chromatids are separated, producing 4 genetically different haploid cells.

Which of the following occurs during meiosis but not during mitosis quizlet?

Which of the following occurs during meiosis but not during mitosis? Synapsis occurs. The pairing of homologous chromosomes that only occurs during prophase I of meiosis is called synapsis.

Does Karyokinesis occur in meiosis?

Meiosis II has Karyokinesis II and Cytokinesis II. The events of meiosis II are similar to mitosis. Hence it is also called mitotic meiosis. At the end of meiosis a diploid parental produces four haploid daughter cells.

Which does not happen during prophase?

Crossing over is the only answer choice that does not occur during mitosis. Crossing over occurs during prophase I of meiosis and involves swapping of genetic information between homologous chromosomes. This require the formation of tetrads, which does not occur during mitosis.

Which does not occur in prophase?

Assembly of mitotic spindle. Chromosomes at the spindle equator. Condensation of chromosome. Disappearance of nuclear membrane and nucleolus.

Which of the following events does not occur in prophase II but does occur in prophase 1?

Crossing over does not occur during prophase II; it only occurs during prophase I. In prophase II, there are still two copies of each gene, but they are on sister chromatids within a single chromosome (rather than homologous chromosomes as in prophase I).
