WebThe result is an exchange of genetic material between homologous chromosomes. As prophase I progresses, the chromosomes begin to condense. The homologous chromosomes remain attached to each other at the centromere. Following crossing over, the connection between homologous pairs is removed.

WebGenes that are located on the same chromosome are called linked genes. Alleles for these genes tend to segregate together during meiosis, unless they are separated by crossing-over. Crossing-overoccurs when two homologous chromosomes exchange genetic material during meiosis I. WebThe process of crossing over occurs during meiosis and involves the exchange of genetic material between homologous chromosomes. This allows for a variety of different combinations of alleles to be generated, which contributes to an increase in the genetic diversity of the children.

Chromosomes exchange genetic material during meiosis in a process called … Chromosomal crossover, or crossing over, is the exchange of genetic material during sexual reproduction between two homologous chromosomes' non-sister chromatids that results in recombinant chromosomes. It is one of the final phases of genetic recombination, which occurs in the pachytene stage of prophase I of meiosis during a process called synapsis. Synapsis begins before the synaptonemal complex develops and is not completed until near the end of prophase …
