== == Yes That's correct In Meiosis Stage 2 The Chromosomes must in effect rip a little peice of each other off in order to conduct Mitosis Again and to make the last two gametes and Within a female it is used also to create Polar bodies in the female gamete cell Hope This Helped :]

When do stages of meiosis recombination or crossing over occur?
Crossing over occurs during Prophase I.
What happens to each pair of duplicated homologous chromosomes during meiosis 1?
pairing of homologous chromosomes and recombination of genetic material takes place
What phase does meiosis crossing over occur?
prophase 1.
When does crossing over occur im meiosis?
it takes place in the metaphase
Why mitotic cell division is called homotypic cell division?
Mitotic cell division is called homotypic cell division because no crossing over is occur in this division and pairing of homologous cromosome is also not occur. So caracteristics of daughter cells is same as mother cell. As there is no variation occur, so this type of cell division may called homotypic cell division.
Pairing of homologues and crossing over occur during?
prophase I
What is exchange of parts of 2 homologues called?
Crossing over
What does the term chiasma refer?
A structure that holds together homologues during crossing over
When does crossing over occur in meiosis?
Crossing over occurs during Prophase I.
When does crossing over occur in this meiosis?
Crossing over occurs during synapsis, prophase I.
When do stages of meiosis recombination or crossing over occur?
Crossing over occurs during Prophase I.
What happens to each pair of duplicated homologous chromosomes during meiosis 1?
pairing of homologous chromosomes and recombination of genetic material takes place
In which phase will crossing-over occur?
Crossing over occurs during Prophase I of meiosis.
Synapsis and crossing over occur during?
prophase I
What phase does meiosis crossing over occur?
prophase 1.
How does crossing over incrase phenotypicvariation in a population?
crossing over allows new genes to be made by the crossing over itself or by mutations that occur in the genes as crossing over occurs. since the phenotype is the physical appearance of the gene, the crossing over can change the genotype which can change the phenotype.
During which process does crossing-over occur?
crossing over occurs in meiosis I, specifically during prophase
