Workers of Melipona quadrifasciata anthidioides (Lepeletier, 1836) develop their ovaries and lay eggs, therefore the production of vitellogenin is expected.

The ridgetail white shrimp Exopalaemon carinicauda has the potential to be used as a useful experimental organism in the field of crustacean research due to its transparent body, large egg, and short reproductive cycle. However, little is known about the

Vitellogenin gene family in vertebrates: evolution and functions
The vitellogenin gene family is constituted of variable gene numbers encoding for polypeptides that are precursors of yolk proteins and derivatives in oviparous and ovoviviparous vertebrates.

Vitellogenins - Yolk Gene Function and Regulation in Caenorhabditis elegans
Vitellogenins are a family of yolk proteins that are by far the most abundant among oviparous animals. In the model nematode Caenorhabditis elegans, the 6 vitellogenins are among the most highly expressed genes in the adult hermaphrodite intestine, which
