What else can I help you with?
How does prophase you of meiosis differ from prophase of mitosis?
a. chromatids do not separate at the centromere in anaphase I. b. centromeres do not exist in anaphase I. c. crossing-over occurs only in anaphase of miitosis
Crossing over occurs during which phase of meiosis?
Crossing over occurs during Prophase I of meiosis.
How is meiosis related to genes?
Meiosis allows a cell to form into 4 cells (by meiosis 1 (which is literally mitosis) and meiosis 2 (mitosis without DNA replication)) in meiosis 1, the cells exchanges DNA information between homologous pairs, this allows genes to be transferred and creates 4 unique and distinct cells. segragation of alleles occur too.
Meiosis 1 us the same as what other reproductive process?
Meiosis I is similar to mitosis in terms of the separation of chromosomes, but there are key differences. In meiosis I, homologous chromosomes pair up and exchange genetic material through a process called crossing over, leading to genetic diversity in the resulting daughter cells. Additionally, meiosis I results in cells with half the number of chromosomes as the parent cell, whereas mitosis produces identical daughter cells with the same number of chromosomes as the parent cell.
What happens to a parent cell at the end of meiosis 1?
the formation of two daughter cells with genetically different material (from each other and from parentbecause of the crossover of the chromatids during prophase 1, the chromosomes at the end of Meiosis 1 will be unique in each cell.This is the reason why siblings don't look the same, yet they look similar to each other and resemble slightly to their parents
When does crossing over happen in mitosis 1?
Mitosis does its crossing over in prophase
Which of the following occurs in meiosis but not mitosis?
Meiosis is the division of the gametes(sex cells), haploid (n) Mitosis is cell division, diploid (2n) In meiosis, there are the similar cycles (prophase, metaphase, anaphase, and telophase), but there are two cycles of each (ex: prophase 1, prophase 2 ETC).
How does prophase you of meiosis differ from prophase of mitosis?
a. chromatids do not separate at the centromere in anaphase I. b. centromeres do not exist in anaphase I. c. crossing-over occurs only in anaphase of miitosis
What phases are found in both meiosis and mitosis?
The phases found in both meiosis and mitosis are prophase, metaphase, anaphase, and telophase. In meiosis, there are two rounds of division (meiosis I and meiosis II), while mitosis only involves one round of division.
Does the nucleus disappear during mitosis and meiosis?
No, the nucleus does not disappear during mitosis or meiosis. It undergoes changes in structure and organization, such as condensation of the chromatin into visible chromosomes, but the nucleus remains present throughout these processes to ensure proper segregation of genetic material.
What happens to homologous chromosomes during prophase 1 of meiosis which does not occur during prophase of mitosis?
During prophase I of meiosis, homologous chromosomes pair up and undergo crossing over, where segments of DNA are exchanged between them. This does not occur during prophase of mitosis, where homologous chromosomes do not pair up or undergo crossing over.
What is the first phase in meiosis?
Meiosis 1: Prophase 1, Metaphase1, Anaphase 1, Telophase 1. Meiosis 2: Prophase 1, Metaphase 2, Anaphase 2, Telophase 2. Makes 4 daughter cells that contain 4 chromosomes each.
Does crossing over occur during prophase 2 of meiosis?
No, crossing over occurs during prophase 1 of meiosis, not prophase 2.
Crossing over occurs during which phase of meiosis?
Crossing over occurs during Prophase I of meiosis.
What happens during prophase you that does not happen during mitosis?
During prophase in meiosis, homologous chromosomes pair up and undergo crossing over, exchanging genetic material. This process does not occur during mitosis, where individual chromosomes line up and separate without crossing over.
Each phase of mitosis?
The four stages of Mitosis is: Prophase: the first stage of mitosis or meiosis in eukaryotic cell division, during which the nuclear envelope breaks down and strands of chromatin form into chromosomes. Metaphase:the stage in mitosis or meiosis in which the duplicated chromosomes line up along the equatorial plate of the spindle fibers Anaphase:The stage of mitosis and meiosis in which the chromosomes move to opposite ends of the nuclear spindle fiber. Telophase: The final stage of mitosis or meiosis during which the chromosomes of daughter cells are grouped in new nuclei.
What are the step to meiosis?
The steps to Meiosis are ;~ Prophase 1~ Metaphase 1~ Anaphase 1~ Telephase 1~ Prophase 2~ Metaphase 2~ Anaphase 2~ Telephase 2
