The daughter cells produced by mitosis are identical, whereas the daughter cells produced by meiosis are different because crossing over has occurred. 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 is true about meiosis?
So, the correct answer is ‘Meiosis produces gametes that contain one complete haploid set of chromosomes’
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 is wrong for meiosis?
No meiosis can occur in haploid cells. A haploid organism (n) produces gametes (n) by mitotic division. These gametes (n) are then fused by fertilization to produce a zygote which is diploid. This zygote or diploid cell then undergoes meiotic division to again produce a haploid organism (n).
Which is true about meiosis and mitosis?
Meiosis involves 2 rounds of cell division; mitosis involves one. Meiosis gives rise to 4 daughter cells; mitosis gives rise to 2. The 2 daughter cells of mitosis are identical to each other; the 4 daughter cells of meiosis are different from each other and different from the cell that produced them.
What event occurs during meiosis I and meiosis II quizlet?
In telophase I and cytokinesis, this cell divides into two cells, while the nucleus is formed around chromosomes of each cell. Therefore, in the first phase, the diploid cell is divided into two haploid cells. Meiosis II consists of prophase II, metaphase II, anaphase II, telophase II and cytokinesis.
What occurs during meiosis that does not occur during 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.
Which of the following occurs during mitosis but not meiosis?
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.
What occurs during meiosis but not mitosis IB?
What occurs during meiosis but not mitosis? Spindles are formed from microtubules. Chromosome number is conserved. Homologous chromosomes pair up.
What is meiosis and where does it occur?
Meiosis is the process of cells splitting into four haploid cells, thus reducing the chromosome number by half in each cell. … Meiosis occurs in the sex cells, so the sperm and egg cells in the human body, to create even more of themselves.
What organisms are haploid?
Haploid gametes are produced during meiosis, which is a type of cell division that reduces the number of chromosomes in a parent diploid cell by half. Some organisms, like algae, have haploid portions of their life cycle. Other organisms, like male ants, live as haploid organisms throughout their life cycle.
