1.

The Mullerian duct differentiates into these structures:

Select one:

a. v....a...g...i...n....a

b. Wolffian duct

c. epididymis, vas deferens, seminal vesicles

d. ovaries

e. fallopian tubes, uterus, internal half of Va...gi....na......

2.

An individual who is XY, but does not have functional androgen receptors, will have the following phenotype (morphology):

Select one:

a. ovaries and female-like genitalia

b. ovaries and female-like genitalia, and also Wolffian duct differentiation

c. ovaries and male-like genitalia

d. testes and female-like genitalia

e. testes and male-like genitalia, and also Mullerian duct differentiation

Answer 1

Question 1.

E. Fallopian tube , uterus , internal half of vagin a.

Estrogen Induces the Mullerian (Paramesonephric) ducts to become:

Uterine Tubes
Uterus
Cerv ix
Upper 1/3rd of the vagin a.

Question 2.

D. testes and female-like genitalia

XY individual has TDF develops testes that make T but lacks a functional androgen receptor, so they develop female external genitalia
- Also, because testes still make MIH, the mullerian duct atrophies but because there are no T receptor, the wolffian duct also regresses so there is NO internal genitalia
- Results in XY person with testes that has female external genitalia but lacks internal genitalia of either sex and vag ina fails to fully develop
