Dear Tutor, can you help with the bellow question and explanation why:

Dr. Jones has a group of mother rats which did not receive much licking and grooming care themselves when they were babies.

As mothers, they are likely to display [high/low] licking and grooming behavior:

The level of expression of estrogen receptors in their preopic area will be [high/low]:

Suppose Dr. Jones had stroked these mothers, when they were babies, with a Q-tip. How would that affect their maternal behavior?

How would that affect their estrogen receptor gene in the preoptic area?

Tamoxifen is an estrogen receptor antagonist. If given to mothers at the end of pregnancy, how would their maternal behavior be affected?
