Evolution of the parthenogenetic rock lizard hybrid karyotype: Robertsonian translocation between two maternal chromosomes in Darevskia rostombekowi. Chromosoma. 2020 Dec;129(3-4):275-283. doi: 10.1007/s00412-020-00744-7. Epub 2020 Oct 30.

A protein MLH1 employed in DNA mismatch repair also appears to be involved in this meiotic process.
