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.
