The gene Brachyury promotes development of the notochord and the vertebrae in vertebrate animals.Among the rodents, most species have a long tail, but capybaras have a very short tail.What is the most likely difference you might expect to see for the Brachyury gene in capybaras compared to long-tailed rodents?
A)A smaller range of gene expression
B)Deletion of the gene
C)Higher levels of expression
D)An expanded range of gene expression

Question

Capybaras having a short tail suggests that the Brachyury gene might have a smaller range of expression, leading to less development of structures like the tail.
