The genotype for males is: "XY"
A Punnet square has 2 parts on the left and 2 parts on the top. It is used to help make sure you don't forget any parts of combinations. The parts on the sides are combined to make a two part thing in the midde. For example a xx and a xy can combine in the squares to make two xx and two xy squares.
Female have two X chromosomes while males have an X and a Y chromosome.
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.
Maleness is not a genotype but a combination of sex chromosomes. A normal human male has an X as well as a Y chromosome.
XY are used to designate the Cartesian coordinates for the person reviewing the x-ray to allow them to locate things.
2-4x is an expression - neither an equation nor an inequality. An expression does not have xy coordinates.
