Detailed explanation-1: -Turner syndrome, a condition that affects only females, results when one of the X chromosomes (sex chromosomes) is missing or partially missing. Turner syndrome can cause a variety of medical and developmental problems, including short height, failure of the ovaries to develop and heart defects.
Detailed explanation-2: -If he passes on his X chromosome, their baby will be genetically female. If the father passes on his Y chromosome, though, their baby will be genetically male.
Detailed explanation-3: -Definition. The X chromosome is one of the two sex chromosomes that are involved in sex determination. Humans and most other mammals have two sex chromosomes (X and Y) that in combination determine the sex of an individual. Females have two X chromosomes in their cells, while males have one X and one Y.
Detailed explanation-4: -Several genes on the X chromosome play an important role in sex development in males and females, gametogenesis, and hypothalamic-pituitary (gonadotrope) function (e.g., androgen receptor[AR], ANOS1 [also calledKAL1], DAX1[NR0B1], MAMLD1, SOX3).
