What happens in meiosis during anaphase I?
The chromosomes split equally and move to the opposite sides of the cell.
What is a sudden change in chromosomes called?
meiosis
A cell with half the number of chromosomes is called?
Haploid cell
What is the process in which homologous pairs of chromosomes separate and move apart is known as?
The process which you are talking about is "Meiosis"... Actually, this process is carried out in gamete producing cells like sperms and eggs. Meiosis process is divided into two parts: Meiosis I and Meiosis II.Meiosis I has four phases: Prophase I, Metaphase I, Anaphase I nad Telophase I.During Anaphase I of Meiosis I of Meiosis cell division, homologous pairs of chromosomes are separated and stretched toward opposite poles of the cell with the help of Microtubules organelle of the cell.
How do the chromosomes get to the stage of meiosis prophase?
A nucleus is signals the rest of the cell that the cell is ready to undergo meiosis, in which case the chromosomes begin to condense with the help of histones, which is the beginning of prophase I of meiosis.
When chromosomes separate what is the process called?
This process is called meiosis.
Main stage of meiosis?
The main stage of meiosis is called the "reduction division" or "meiosis I." During this stage, homologous chromosomes pair up and exchange genetic information through a process called crossing over. They then separate, resulting in two cells with half the number of chromosomes as the original cell. Meiosis II then follows, where sister chromatids separate, resulting in four non-identical daughter cells.
What happens in meiosis during anaphase I?
The chromosomes split equally and move to the opposite sides of the cell.
What A photograph of homologous chromosomes called?
meiosis
What is a sudden change in chromosomes called?
meiosis
What are the two cells called that the parent cell split into?
In animal cells (meiosis) the parent (which is a diploid cell with homologous pairs of chromosomes) seperates into two daughter cells containing the replicated pairs of sister chromatids. The process of meiosis is begun again (meiosis II) from which the sister chromatids separate into individual chromosomes. Then, the two diploid cells separate into 4 haploid daughter cells containing 1 chromosome. This is a generalized answer without the steps of meiosis described.
How many divisions occur in meiosis?
Meiosis does in fact divide twice, once in meiosis I (cytokinesis) and meiosis II (cytokinesis) basically it divides into four daughter cells at the end of meiosis. Two from meiosis I and four in meiosis II
What are Homologous chromosomes that occurs in meiosis but not mitosis is called?
Tetrad
The pairing of homologous chromosomes during meiosis is called what?
synapsis
What is the process called when an exact copy of the chromosomes is made?
Meiosis
When chromosomes do not part in meiosis like they should?
Called nondisjunction.
What is it called when cells are copied with half he number of chromosomes?
Meiosis
