Answer:
the process whereby nonsister chromatids exchange genetic material
Explanation:
Crossing-over is a unique phenomenon which occurs only in the prophase I stage of meiotic division i.e. meiosis I. It is the process whereby nonsister chromatids of homologous chromosomes (similar but non-identical chromosomes from male and female parents) exchange their genetic material.
This exchange between nonsister chromatids aids in genetic variation among species that reproduce sexually via meiosis. Hence, meiosis, which is peculiar to sexually-reproducing organisms is the only way that promotes genetic variation in species.
