The random distribution of homologous chromosomes during meiosis is called?
a polar bodyEdited answer:Synapsis
How does a tetrad form in prophase I of meiosis?
In prophase I, doubled homologous chromosomes group together to form a tetrad.
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 happens during meiosis that ultimately results in a defect characterized by the deletion of chromosomes?
Nondisjunction occurs in too many cells or too few cells causing defects
What is the difference between anaphase 1 and anaphase 2 in meiosis?
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!
When do homologous chromosomes separate into the daughter cells?
They are separated in Anaphase I of Meiosis I.
Occurs when homologous chromosomes do not separate in meiosis?
Nondisjunction occurs when homologous chromosomes do not seperate. -Amber ^-^
What is a failure of homologous chromosomes to separate in meiosis?
Nondisjunction
Nondisjunction occurs when?
homologous chromosomes fail to separate during meiosis
Is homologous chromosomes only present in cells that undergo meiosis?
Usually they dont as homologous chromosomes form bivalents with other homologous chromosomes and crossing over occurs between the 2. But if a chiasmata does form between the t homologous chromosomes they can change information.
When do sister chromatid separate during meiosis?
The sister chromatid separate during anaphase II in meiosis. During anaphase I homologous chromosomes get separated.
What is a meiotic nondisjunction event?
Nondisjunction is when homologous chromosomes fail to separate in Meiosis I, or sister chromatids fail to separate in Meiosis II or Mitosis. This results in daughter cells with an incorrect number of chromosomes.
How many homologous chromosomes interact with each other or dont during mitosis and meiosis?
In mitosis, the homologous chromosomes dont interact, but in meosis, they separate during Anaphase 1. In mitosis, the homologous chromosomes dont interact, but in meosis, they separate during Anaphase 1.
Failuare of homologous chromosomes to separate properly during meiosis result in gametes with too many or too few chromosomes?
nondisjunction
Do homologous chromosomes separate only in meiosis?
yes. in mitosis there is separation of sister chromatids
What division of meiosis splits chromosomes?
In anaphase I of meiosis, the homologous pairs of chromosomes separate. Due to DNA replication and crossing over during prophase I, these chromosomes consist of a pair of non-identical sister chromatids. During anaphase II of meiosis, the sister chromatids separate into individual chromosomes.
What is unique to mitosis and not a part of meiosis?
homologous chromosomes behave independently Pairing of homologous chromosomes allowing independent segregation and crossing over is unique to meiosis. In mitosis, homologous chromosomes behave independently.
