An empty square. One that does have the trait would have the square filled in with a color.

How many genotypes are possible in a pedigree of sex linked traits?
xx = normal female x- x = carrier female x- x- = female which has the sex-linked trait xy = normal male x- y = male which has the sex-linked trait
What would represent a colorblind male in a pedigree?
Filled squares

What is the pattern of sex linked inheritance?
In humans sex linked traits are passed on the X chromosome. (For the purpose of this discussion the trait being passed is recessive.) This means that a male parent cannot pass the characteristic on to his male offspring, but he can pass the trait on to his female offspring. The female parent can pass the trait on to any of her offspring. Both parents must carry the allele for the sex-linked trait (and pass it on) in order for a female child to have the characteristic. Male children that get the trait from their mother will have the trait no matter what the genetics of the father. If the female parent is heterozygous for the trait 50% of her male children will have the characteristic no matter the father's genetics for that trait. Assuming that the characteristic is not lethal and both parents are "carriers" (keep in mind that the father displays the trait and a heterozygous mother will not)... 50% of the sons will have the trait, 50% of the sons will not have the trait, 50% of the daughters will be homozygous for the trait and 50% will by heterozygous "carriers".
How are females and males represented in a pedigree?
Easy box kind of a square=Male(boy) a circle=Female(girl) I am 100% sure about that answer

How is a male shown on a pedigree?
In a genetic pedigree, males are represented by squares while females are represented by circles.
What is the pedigry?
A pedigree is a diagram of family relationships that uses symbols to represent people and lines to represent genetic relationships.Pedigrees make it easier to visualize relationships within families are often used to determine the mode of inheritance of genetic diseases.Symbols in pedigree:Squares represent males and circles represent females.Horizontal lines connecting a male and female represent mating.Vertical lines extending downward from a couple represent their children.If the purpose of a pedigree is to analyze the pattern of inheritance of a particular trait, it is customary to shade in the symbol of all individuals that possess this trait.

A male will always transmit a recessive trait to his son?
no not always they can transmit a dominate trait also
What inheritance pattern in a pedigree would allow you to decide that a characteristic is Linked?
"Any trait that showed up in the males only would be considered to be sex-linked to the X chromosome. This is because a male being XY would show the effect and the females who were carriers being XX would obviously have the normal ( non mutant ) X chromosome too, which dominates the mutated one. A classic example of X linked ( sex linked) traits is Haemophilia who are nearly always male. But a female haemophiliac is possible but could only be produced from having a haemophiliac father and a carrier mother ( A rare combination) and therefore inheriting two copies of the mutated recessive x "bleeding" gene. Hope this helps." -From blurtit.com

Is thoroughbred male horse bigger than thoroughbred female horse?
That depends on the pedigree and bloodlines of the horse
