It can also happen during mitotic division, which may result in loss of
heterozygosity. Crossing over is essential for the normal segregation of
Meiosis I separates homologues from each other. Meiosis II separates sister
chromatids from each other. Crossing over occurs in meiosis I. During crossing
However, during prophase I homologous chromosomes pair up and become
attached to one another. At this time, crossing over moves sections of DNA ...
Aug 27, 2014 ... It can, but there is usually enough of a spacer that it happens between genes. If it
does, crossover will often occur in the non-coding introns.
During crossing over the two chromosomes of one pair exchange genetic
information. In order to be viable they always have to exchange the same part.

This process, also known as crossing over, creates gametes that contain new
combinations of genes, which helps ... What happens during recombination?
Further genetic variation comes from crossing over, which may occur during
prophase I of meiosis. ... Synapsis and crossing over occur only in meiosis.
