Term
Predict for each of the cases below the sexual phonotype of
the following structures: gonads, mullarian duct features, woffian
duct features, and external genitalia. Briefly justify your answers.
o An XX individual in which both ovaries failed to develop
Give this one a try later!
♣ both duct develops, male gonads,
if no MIH then the mullarian duct ♣ Sterile, mullarian duct still
forms but no gonads, female
, will develop as well as external genetalia
Wolffarian since testosterone is
present
o Negative feedback shifts to
positive after a threshold yes, the medial proptic nuclei and
of estrogen exposure has anteroventral periventricular
been surpassed

Predict for each of the cases below the sexual phonotype of
the following structures: gonads, mullarian duct features, woffian
duct features, and external genitalia. Briefly justify your answers.
o An XY individual in which androgen receptors are absent
Give this one a try later!
o A difference between mice that have the Y chromosome (XY- and XY-Sry)
versus those that do not (XX and XX-Sry)
o The complement of sex chromosomes (XX versus XY) is made independent of
gonadal sex -Y chromosome no longer testis-determining
o Sex biased expression of X and Y genes
o The chromosomes are the same but the differentiation is between what has
an Sry vs ones that do not
♣ both duct develops, male gonads, if no MIH then the mullarian duct will
develop as well as Wolffarian since testosterone is present
, ♣ elevated estrogen secretion accompanies follicular development during
diestrus and proestrus stimulating estrus behavior and cornification of vaginal
epithelial cell
♣ progesterone concentrations increase abruptly prior to ovulation to induce
mating behavior
♣ Develop external female phenotype, femainized sexually dimorphic and
female gender identity
♣ Doesn't prevent masculinization of the brain
Don't know?

brain? induced pseudopregnancy
if so where is it located?
What neural component is required Are there estrogen receptors in the
for estrogen included positive male brain?

Graafian exposure to LH at time of LH surge
Give this one a try later!
How did determination vs
predisposition impact on the What neural component is required

ex1: Do individual differences in behavior necessarily reflect
differences in hormone concentrations in the blood?
Give this one a try later!
o Yes
o Chemical communication occurs at all levels of biological organization
o Intracrine mediation: intacrine substances regulate intracellular events
