• B. XX sex chromosomes produce male in Drosophila
• C. ZZ sex chromosomes determine female sex in birds
• D. XO sex chromosomes determine male sex in Grasshopper.

Answer 1

The correct option is A XO condition as in Turner's syndrome determines the female sex

Turner syndrome (TS), also known as 45,X or 45,X0, is a condition in which a female is partly or completely missing an X chromosome. Signs and symptoms vary among those affected. Often, a short and webbed neck, low-set ears, low hairline at the back of the neck, short stature, and swollen hands and feet are seen at birth. Typically, they develop menstrual periods and breasts only with hormone treatment, and are unable to have children without reproductive technology. Heart defects, diabetes, and low thyroid hormone occur more frequently.

So the correct option is 'XO condition as in Turner's syndrome determines the female sex'.
