_C. intestinalis_ and _C. savignyi_ can cross-fertilise after removal of the
vitelline enveloppe ([[Byrd and Lambert, 2000|biblio/10602281]]).
+Allele-specific expression in these crosses was studied by [[Wei and coll.,
+2024|biblio/38493164]].
_Ciona robusta_'s sperm can efficiently fertilise _C. intestinalis_ eggs, but
the fertilisation rates are much lower in the reciprocal crosses ([[Suzuki,
