Question 10 Complete 0.00 points out Select one: If an XY embryo has a mutated SRY gene resulting in a nonfunctional TDF, its gonadal tissue will develop into of 1.00 a. testicles b. ovaries C. penis d. vagina e.- it will remain undifferentiated Flag question Question 11 Complete 0.00 points out An XY fetus with a functional SRY gene has a defect in the gene that codes for the production of MIH. The defect results in producing nonfunctional MIH Which statement is FALSE about this individual? of 1.00 Select one Flag question a. The fetus would have male internal genitalia (e.g. prostate gland). b. The fetus would have male external genitalia (e.g. a penis). c. The fetus would have female external genitalia (e.g., a clitoris). d. The fetus would have testicular tissue e. The fetus would have female intemal genitalia (e.g., uterine tissue)

Explanation / Answer

C.. is the answer (i can not write the word because chegg policy is not allow to submit answer with this type of words)

TDF is a testis determining factor which is responsible for normal development of testis, however if it is mutated or non functional, the testis will be remain affected. Other male sex organs re developed from the combinational effect of other gene (SOX9, AMH, MIH etc)

Mullerine inhibitory hormone will stops the development of mullerine duct. Mullerian duct develops into female internal genitalia however if MIH gene is mutated or non function, it will develops in to female internal genitalia. Normal MIH gene is required for formation of male internal genitalia.

A.. the fetus would have male internal genitalia, is a false answer for non functional MIH
