非洲爪蟾
The western clawed frog ("Xenopus tropicalis") is a species of frog in the family Pipidae, also known as tropical clawed frog. It is the only species in the genus "Xenopus" to have a diploid genome. Its genome has been sequenced, making it a significant model organism for genetics that complements the related species "Xenopus laevis" (the African clawed frog), a widely used vertebrate model for developmental biology. "X. tropicalis" also has a number of advantages over "X. laevis" in research, such as a much shorter generation time (&lt;5 months), smaller size ( body length), and a larger number of eggs per spawn.
