A male grasshopper's genotype is XO. A female grasshopper's genotype is XX. X represents the presence of a sex chromosome, and O represents the lack of a sex chromosome.
In the ZW sex chromosome system, the male genotype is ZZ. The letter Z represents the presence of a dominant male-determining gene, while the letter W represents the absence of this gene, which determines female development. Therefore, individuals with the ZZ genotype develop as males in this system.
X chromosome
In humans, which sex chromosome determines if an offspring is a male or female?
Whether they have 2 X chromosomes= girl, of one X chromosome and one Y chromosome= boy

Maleness is not a genotype but a combination of sex chromosomes. A normal human male has an X as well as a Y chromosome.

Fathers pass the Y sex chromosome to their sons, NOT the X sex chromosome.

Women have only X chromosomes. Men have one X and one Y. If the man's sperm has an X chromosomes, the child will be a girl. If the man's sperm has a Y chromosome, the child will be a boy.
Turner syndrome only affects females. They have only one X sex chromosome and their sex genotype is XO. Since they only have one X sex chromosome, they do not have barr bodies.
All people with Klinefelter's syndrome are male because by definition Klinefelter's syndrome is due to a genotype of XXY. The fetus will develop into a male if there are any Ys present at the sex chromosome.
