When do homologous chromosomes separate into the daughter cells?
They are separated in Anaphase I of Meiosis I.
Chromosomes are duplicated?
The chromosomes duplicate themselves in Meiosis 1, however they don't duplicate in Meiosis 2.
Could crossing over occur during second meiotic division?
No, tips of homologous chromosomes cross over in Meiosis I. There are no homologous chromosomes by Meiosis I.
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.
What is a failure of homologous chromosomes to separate in meiosis?
Nondisjunction
What would be the outcome of meiosis you if none of the homologous chromosomes separate at anaphase?
Each duplicated chromosomes would be pulled to one side or the other spindle poll, which is what happens in anaphase 1 of meiosis.
What happens in meiosis one that does not occur in meiosis?
the synapsis and crossing over of homologous chromosomes
The pairing of homologous chromosomes before nuclear division happens in what type of cell division?
only in meosis
What happens at the conclusion of meiosis 1?
Homologous chromosomes are separated.
Occurs when homologous chromosomes do not separate in meiosis?
Nondisjunction occurs when homologous chromosomes do not seperate. -Amber ^-^
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.
How does the number of chromosomes in metaphase of mitosis compare to the number of duplicated chromosomes in metaphase 2 of meiosis?
because in metaphase 2 of meiosis there are 2 different cells, which means the chromosomes duplicated
When do homologous chromosomes separate into the daughter cells?
They are separated in Anaphase I of Meiosis I.
What A photograph of homologous chromosomes called?
meiosis
