Turner's Syndrome
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.
XO
Nondisjunction.
it means it has one gene from the dominant trait and one gene from the recessive trait
Turner's Syndrome. People suspect that Joan of Arc had this syndrome.
These genotypes are determined by a human's 23rd pair of chromosomes. If the subject is female, she has two X's reading XX. If it is male, then his genotype will read XY. There is a 50-50 shot of each. This is because a woman donates one chromosome (she only has two X's so it is inevitable that she will donate an X), and a man donates one of his. If a man donates his 'X' then there will be two X's and the child will be female. If he donates his 'Y' then the child will be male.Male is XY, female is XX. There are, however, other genotypes (XXY, XXX, XO...) and not all people have a phenotype that goes with their genotype.
Yes, if the mother had a genotype of AO and the father had one of XO (X being any group).

Turner Syndrome! Because women with the disorder only have one X chromosome
The XO condition is known as Turner's Syndrome.
The human would be female. They would be sterile and her sex organs will not mature.
xx designates a normal human female.
