Karyotypes, sex chromosomes, and meiotic division in spiders
Original language description
From the cytogenetic point of view, spiders are the best studied arachnid order. In spite of this, karyotype data are still available only for less than 2 % of spider species. These data indicate a considerable diversity of diploid numbers, chromosome morphology, and sex chromosome systems in some spider lineages. Most spiders exhibit a standard chromosome structure except for the superfamily Dysderoidea that has holokinetic chromosomes (a derived type of chromosomes without centromere). The unusual multiple sex chromosomes of spiders have received more attention than any other aspect of their cytogenetics. Most species exhibit the so-called X1X20 system with X1X2 males and X1X1X2X2 females. This sex chromosome determination, considered ancestral for spiders, has an unclear origin. Recently found unusual sex chromosome behaviour at meiosis of female spiders may represent a system acting to restrict pairing and recombination to homologous X chromosomes and support the hypothesis on the
