This crossing-over percentage is therefore a measure of their degree of linkage. Specifically, for genes on the same chromosome, the following statements hold true: Crossing-over rate 50% ...

homologous chromosomes—chromosomes of the same shape and genetic set-up—pair-up and exchange genetic information. This DNA ...

Finally, as prophase I draws to a close and metaphase I begins, the crossing-over process concludes, and the homologous chromosomes prepare to separate. When the homologous chromosomes are later ...
