- Only a partial mitochondrial genome was reconstituted in [[Denoeud et al.,
2010|biblio/21097902]], due to cloning and sequencing difficulties that may
have been caused by oligo-dT stretches. A/T-rich codons are more frequent than
- in human.

- Analysis of sex-linked markers supports genetic sex determination with male heterogamety –
that is: X chromosomes for females and Y for males. ([[Denoeud et al., 2010|biblio/21097902]])
