synapsis: see crossing over crossing over, process in genetics by which the two chromosomes of a homologous pair exchange equal segments with each other. Crossing over occurs in the first division of meiosis. At that stage each chromosome has replicated into two strands called sister chromatids.

synapsis [sə′nap·səs]

(cell and molecular biology)

Pairing of homologous chromosomes during the zygotene stage of meiosis.

Synapsis

the paired temporary association of homologous chromosomes during which an exchange of homologous chromosomal areas may occur. Under the influence of various factors, chromosomes readily contract into a ball during synapsis. The British scientist D. E. Moore described this phenomenon and introduced the term “synapsis” in 1895.
