What is the difference between anaphase 1 and anaphase 2 in meiosis?

∙ 12y ago
Hello, Anaphase 1 and 2 are both part of the process of meiosis, the division of sex cells, and they are both phases where chromosomes are being pulled apart by the centrioles. However, in anaphase one the chromosomes are lined up in homologous pairs, meaning that there are two chromosomes side by side, so when the centrioles pull they are separating two unconnected chromosomes. In anaphase two the chromosomes are lined up in single file. So the centrioles are pulling one chromosome apart. It eventually breaks the link at the centromere of the chromosome and results in two sister chromatids.
Hope this is clear enough to understand!

What specific stage in meiosis do homologous chromosomes separate?
Anaphase lAnaphase I
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 distinguishes prophase 1 of meiosis from prophase of mitosis?
In Prophase I of meiosis, a tetrad is formed between 2 homologous chromosomes and their replicates. Small pieces are exchanged between the chromosomes and the tetrad breaks up. Then things happen as usual. So really the only difference is that there's genetic recombination.
What are the two distinct stages of meiosis?
Meiosis I and meiosis II
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.
When do homologous chromosomes move towards opposite poles in meiosis?
In Anaphase I of meiosis.
What stage of meiosis is the chromosome number reduced?
In Anaphase I
What specific stage in meiosis do homologous chromosomes separate?
Anaphase lAnaphase I
During what does the sister chromatids of chromosomes separate and four haploid daughter cells are formed?
Plato users, Meiosis I. i dont know the answer , but this is not the answer !
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
When does independent assortment occur in meiosis?
Independent assortment occurs during metaphase I
What phase in meiosis does the double stranded chromosomes move to the center of the cell and separate?
the double-stranded chromosomes move to the center of the cell and seperate, is in the beginning or end of the meiosis?
Segregation of alleles occurs during?
Segregation.
What are the phases of meiosis 1?
they are prophase I, metaphase I, anaphase I and telophaseI. :)
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.
When does the reduction of chromosomes from the diploid to the haploid number take place?
During meiosis
What happenes in meiosis during anaphase 1?
The tetrads are pulled apart.
