Answer 1

Swyer syndrome is a rare disorder characterized by the failure of the sex glands (i.e., testicles or ovaries) to develop, this condition mainly affectds sexual development,  Girls and women typically have two X chromosomes (46,XX karyotype), while boys and men usually have one X chromosome and one Y chromosome (46,XY karyotype), but in In Swyer syndrome, individuals with one X chromosome and one Y chromosome in each cell, the pattern typically found in boys and men, have female reproductive structures, so people suffering from this condition have typical female external genitalia. In summary, people with Swyer syndrome are born with the appearance of a normal female anatomicaly, except that the child has nonfunctional gonads instead of ovaries or testes, affected individuals have undeveloped clumps of tissue called streak gonads because of the lack of development of the gonads, these residual gonads often become cancerous, hence surgicaly removed.

b) Despite having the XY chromosomal makeup, girls with Swyer syndrome look female and have functional female genitalia and structures including a vag!na, uterus and fallopian tubes, but they lac sex glands because of which ovaries do not develop properly and are replaced by scar tissue.and moreover they lack hormones like estrogen and progesterone, because of which breasts do not develop, uterus will not grow and irregular menstrual flow, conceiving children is also not possible.
