a cell containing 2 sets of chromosomes are known as _____.
Which duct regresses spontaneously in the absence of testosterone?
condition in which an X chromosome is missing producing ovarian dysgenesis with vestigial streak gonads
True or False: only one X chromosome is needed for development of a normal ovary

the differentiation of the external genitalia occurs at weeks _____ of development
What connects the testes to the labioscrotal swellings?
The penile urethra is derived from which portion of the urogenital sinus?
SRY translocation to X chromosome leads to a _____.
This hormone causes the conversion of the urogenital sinus into the prostatic and initial phallic urethra, development of prostate and bulbourethral glands, and also causes the dev
determination of the gonads occurs during weeks _____ of development

primordial germ cells initially migrate to the _____ ridges
concept held by an individual that the individual is male, female, or ambivalent

What regulates the transcription of AMH?
this condition occurs when the urogenital folds fail to fuse properly. causes the urethral opening to be at the tip but located ventrally on the penis
