Which of these does not occur in 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 does not occur in meiosis quizlet?
Which does NOT occur in meiosis? … They undergo “endomitosis,” in which one extra chromosome replication results in a tetraploid cell before meiosis begins; normal female 2n offspring result without fertilization.
What occurs during meiosis that does not occur during mitosis?
The events that occur in meiosis but not mitosis include homologous chromosomes pairing up, crossing over, and lining up along the metaphase plate in tetrads.
Which of the following events does not occur during meiosis one?
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 does not occur 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 of these does not occur during prophase I of meiosis?
E) Homologous pairs of chromosomes align at the metaphase plate does not occur during prophase I of meiosis.
Which does not occur in 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 events does not occur during telophase?
Which of the following does not occur during telophase: The nuclear membrane disappears. Which is not correct about the way prokaryotes divide? The replication of DNA occurs in one direction around the circle.
What occurs during meiosis but not 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.
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 one of the following does not occur during anaphase of mitosis?
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.
