Recombination and Meiosis

The Cochliopodium genome includes genes whose functions are employed in the process of genetic recombination suggesting the possibility of a sexual stage.[7] The genome sequence of Cochliopodium minus contains a complete set of genes necessary for meiosis a key stage of sexual reproduction.[8]
