What are the five phases of meiosis 1?
Meiosis.....................produces gametes or sexual cells, which contain half the chromosomesbecause the sexual union of male and female will contribute the otherhalf.
Where does meiosis take place in a mushroom?
Meiosis in a mushroom takes place in the basidia, which are specialized cells found on the gills in the underside of the mushroom cap. Basidia undergo meiosis to produce spores, which are the reproductive cells of the mushroom.
What stage of mitosis does replication happen in?
Replication does not take place during mitosis. It takes place before meiosis begins.
Relate Mendel's two laws of inheritance to the behavior of chromosomes in meiosis?
Mendel's Law of Segregation explains how alleles separate and segregate into different gametes during meiosis, just like how chromosomes separate into different daughter cells during anaphase I of meiosis. Mendel's Law of Independent Assortment relates to how different homologous pairs of chromosomes line up randomly on the metaphase plate during meiosis I, leading to a random assortment of genes into gametes.
When does Meiosis take place in an animal with a diplontic life cycle?
Meiosis takes place during the formation of gametes in animals with a diplontic life cycle. This occurs when germ cells undergo meiosis to produce haploid gametes (sperm and egg cells) that will later fuse during fertilization to form a diploid zygote.
When does the reduction of chromosomes from the diploid to the haploid number take place?
The reduction of chromosomes from the diploid to the haploid number takes place during meiosis, specifically during the first division called meiosis I. In this phase, homologous chromosomes pair up and exchange genetic material, resulting in the separation of the homologous pairs into different daughter cells.
What do Meiosis I and Meiosis II have in common?
Both Meiosis I and Meiosis II involve the processes of prophase, metaphase, anaphase, and telophase. Additionally, both stages result in the formation of haploid cells with half the number of chromosomes as the original cell.
When does metaphase occur?
Metaphase occurs during meiosis and mitosis. These processes are how most cells reproduce to make two new cells. Some use binary fission.
Does meiosis take place in jellyfish?
Yes, anything which produces a zygote goes through meiosis.
Why does meiosis take place where does it take place?
It takes place in the sex organs. So it can produce 4 gametes.
What are the five phases of meiosis 1?
Meiosis.....................produces gametes or sexual cells, which contain half the chromosomesbecause the sexual union of male and female will contribute the otherhalf.
What are the major events that take place during Meiosis you and Meiosis II?
After the 1st meiotic division there are 2 diploid cells. During Meiosis II, these cells are divided (the same steps as the first Division) - and produce 4 daughter cells. These cells (gametes) have half the number of chromosomes of the original cell and so are called hapliod. Phases: 1) Prophase II - cells contain one of each homologous chromosome - but each are in their replicated form (i.e. 2 chromatids attached together) 2) Metaphase II - Chromosomes align in the middle of the cell 3) Anaphase II - Chromatids separate 4) Telophase II - 4 haploid cells formed
What is the cell division that take place in the sperm and ovum?
Meiosis.
When does the division of cytoplasm take place?
cytokinesis which begins in anaphase but is mostly performed during telophase
When does inedependent assortment take place in meiosis?
Independent assortment occurs during meiosis I, specifically during the metaphase I stage when homologous chromosomes line up randomly along the metaphase plate. This random alignment results in different combinations of maternal and paternal chromosomes being separated into daughter cells during anaphase I, contributing to genetic diversity.
Between which two structures does crossing-over take place during meiosis?
Crossing-over takes place between homologous chromosomes during meiosis.
Where in the humans would you expect to find meiosis take place?
Gametes
