What happens in meiosis that doesn’t happen in mitosis?
In meiosis , synapsis ( Pairing of homologous chromosome ) , Crossing over ( exchange of chromosomal segment between nos sister chromatids ) occurs which does not occur in mitosis.
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.
What stage does meiosis have that mitosis does not?
Meiosis: Prophase I consists of five stages and lasts longer than prophase of mitosis. The five stages of meiotic prophase I are leptotene, zygotene, pachytene, diplotene, and diakinesis. These five stages do not occur in mitosis. Genetic recombination and crossing over take place during prophase I.
Why does crossing over occur in meiosis but not mitosis quizlet?
Mitosis produces cells with the same number of chromosomes as the parent cell whilst meiosis produces half the number of chromosomes as the parent cell. There’s no pairing or separating of homologous chromosomes in mitosis and so no crossing over of independent segregation of homologous chromosomes.
What does not happen 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.
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.
Which of the following occurs during meiosis but not during?
(d) Synapsis occurs during meiosis but not during mitosis during mitosis.
Which of the following occur during meiosis I but not during meiosis II?
In meiosis I, homologous chromosomes separate, while in meiosis II, sister chromatids separate. Meiosis II produces 4 haploid daughter cells, whereas meiosis I produces 2 diploid daughter cells. Genetic recombination (crossing over) only occurs in meiosis I.
Which of the following occurs during meiosis II but does not occur as part of meiosis I?
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. This occurs in meiosis I in a long and complicated prophase I, split into five sub-phases.
What are the major differences between mitosis and meiosis quizlet?
What are the principal differences between mitosis and meiosis? Mitosis results in the production of two genetically identical diploid cells, whereas meiosis produces four genetically different haploid cells.
