How many times does the cell divide during meiosos?
Chromosones are divided two times. Once during meiosis I and once during meiosis II.
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.
How are crossing over and recombination related?
Genetic recombination occurs during meiosis cell division. As genes cross over during this process, scientists track the genes to study their linkage.
What are the importance of chromosomes?
chromosomes are filamentous structures which are present in the nucleus as chromatin reticulum and are visible only during cell division..this is what i know about choromos..lol
When do stages of meiosis recombination or crossing over occur?
Crossing over occurs during Prophase I.
Explain the importance of crossing-over during the first division of meiosis?
The first division reduces the number of Chromosomes by half.
When does crossing over occure?
prophase I
How many times does the cell divide during meiosos?
Chromosones are divided two times. Once during meiosis I and once during meiosis II.
What does the term crossing over mean in context of nuclear division?
Crossing over between pairs of homologous chromosomes to form chiasmata is known as pachytene. It occurs during prophase I in meiosis.?æ
What is the process whereby genetic material is exchanged between homologous chromosomes during synopsis of the first meiotic division?
Crossing over or homologous recombination
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.

What happens if nondisjunction occurs during meiosos?
If nondisjunction occurs during meiosis the result could be a wide range of mutations. Most likely it would result in mosaicism meaning there will be a mixture of affected cells and non affected cells.
When does crossing occurs in meiosis?
Crossing over occurs during Prophase I.
What happens during crossing?
Crossing over is the process in which babies are made.
When does crossing over occur in meiosis?
Crossing over occurs during Prophase I.
