The Development of Normal Maternal Behavior in Female Mice Depends

The development of normal maternal behavior in female mice depends on interactions between the female and her young and the presence of a gene called fosB. In mice with functional fosB genes, a sequence of events occurs after babies are born.
Arrange the events in their normal sequence following the birth of baby mice for a wildtype female.

A) Female inspects newborns.
B) Auditory, olfactory, and tactile signals about the young are sent to the hypothalamus.
C) Neural circuitry within the hypothalamus is modified, facilitating maternal behavior.
D) Female crouches over young and retrieves them if they leave the nest.
E) The gene fosB is activated, producing protein that activates other genes.
