Notes.
Rhombus (⧫) indicates a partially formed individual.
Asterisks (*) indicate (i) fully-formed individuals with abnormalities (and after the birth, the mother BUT44 ate the offspring) and (ii) sex was not detectable in embryos.
Question mark (?) indicates that the sex was not defined because (i) the mother ate the offspring, or (ii) the sons were malformed and composed of an amorphous mass in the terminal region of the body, or (iii) the animals died during the weekend and they were found deteriorated physically on Monday.
