the male has the x and y and the female has th x's
Y chromosome
Y i think
When a person is born they get one chromosome from the mom and one from the dad. A female has XX chromosomes a male has XY Cromosomes. So a male would get the Y from the dad and the X from the mom.
The gene for this trait is likely located on the Y chromosome. The Y chromosome is passed down from father to son, and since only males have a Y chromosome, the trait will only be passed down through male lineage.
sex-linked disorders
Y chromosome
Y i think
The y-chromosome is only present in males. Men will a y-chromosome identical to that of their father, and his father, and his father, etc.
Males have both X & Y chromosomes
Males possess one X chromosome and one Y chromosome.
When a person is born they get one chromosome from the mom and one from the dad. A female has XX chromosomes a male has XY Cromosomes. So a male would get the Y from the dad and the X from the mom.
Males typically have one X chromosome and one Y chromosome. This combination of sex chromosomes determines male sex characteristics.
The X chromosome is affected, because there are 2 of them (and a Y chromosome).
y chromosome is the chromosome that makes males, alcoholism has nothing to do with it unless you make the choice to drink
The gene for this trait is likely located on the Y chromosome. The Y chromosome is passed down from father to son, and since only males have a Y chromosome, the trait will only be passed down through male lineage.
sex-linked disorders
Since males are the only sex to have a y chromosome, only males can get genes that are linked to the Y chromosome. This means that some genetic diseases and conditions are more likely to be male such as color blindness.
