A conjunction of pairs of homologous chromosomes of maternal and paternal origin, respectively.
Pairing of homologous chromosomes during an early stage of meiosis.
The process of first maturation division in gametogenesis, in which there is conjugation of pairs of homologous chromosomes forming double or bivalent chromosomes. In the resulting meiotic division, the chromosome number is reduced from the diploid to the haploid number. It is at this stage that crossing over occurs.
The pairing of similar chromosomes during meiosis.
