The exchange of segments of chromatids during synapsid is known as

answer:

crossing over

explanation:

the tight pairing of the homologous chromosomes is called synapsis. in synapsis, the genes on the chromatids of the homologous chromosomes are precisely aligned with each other. an exchange of chromosome segments between non-sister homologous chromatids occurs and is called crossing over.
