A heterozygous genotype is always a capital letter, then a lowercase letter.
Example:
Hh
XrXr
Novanet Swag
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.
The ratio of a human baby being a male to being a female is 1:1.That means that the baby has a 50% of being a male, and a 50% of being a female.A male human has the genotype of XY.A female human has the genotype of XX.Some mutated organisms have an XXY or XYY for a genotype.

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.
Red eyes is a dominant sex-linked gene in the fruit fly. Males with red eyes have the genotype XRY, where R is for the red gene.

If the male parent has genotype AS and the female parent has genotype AA what is the offspring?
The genotype for a male is XY. A female is XX. The 23rd homologous pair is the sex gene that determines this.
XY

Maleness is not a genotype but a combination of sex chromosomes. A normal human male has an X as well as a Y chromosome.
Male reproduction system
One way to determine the male's genotype would be to breed him to females with a known genotype of Black-Black. If any resultant calves were born with a white coat, you would then know that the male were Black-White. If calves were consistently black coated, you could be fairly certain he was also of the Black-Black genotype.
