crossing-over
crossing-over The exchange of genetic material between
homologous chromosomes by
breakage and reunion. This occurs during pairing of
chromosomes at prophase I of
meiosis, and in some organisms (for example certain fungi, and insects such as
Drosophila) may also occur at
mitosis. The temporary joins between chromosomes during crossing-over are called
chiasmata.
