Future directions Several challenges now face those researching spermatogenesis genes on the Y chromosome.
A female child inherits two X chromosomes, while a male child inherits an X chromosome from one parent and a Y chromosome from the other.
The sons inheriting one defective gene will develop the disorder because a male has only one X chromosome, which he receives from his mother and one Y chromosome from his father.
A male child inherits an X chromosome from his mother and a Y chromosome from his father.
When a man carries a premutation on his X chromosome, it tends to be stable and usually will not expand if he passes it on to his daughters (he passes his Y chromosome to his sons).
Normally, females have two X chromosomes, and males have one X and one Y chromosome.
While the X chromosome carries many genes, the Y chromosome carries almost none.
Females have two X chromosomes (the XX combination); males have one X and one Y chromosome (the XY combination).
Males have one X and one Y chromosome (XY).
The mother passes one of her two X chromosomes down to her child, and the father passes either an X or a Y chromosome to the child.
Females have two X chromosomes, while males have one X and one Y chromosome.
Male sperm cells contain either an X or a Y; if the sperm with the Y chromosome fertilizes an egg, the baby will be male.
Males with this disorder have an extra Y chromosome.
The error that causes the extra Y chromosome can occur in the fertilizing sperm or in the developing embryo.
There are two basic types of DNA testing for ancestry: Y chromosome (Y-DNA) testing and mitochondrial DNA (mtDNA) testing.
The Y chromosome passes from father to son in an almost unchanged state, so shared markers indicate a common patrilineal ancestry.
The most obvious limitation of this type of DNA test is that only men have a Y chromosome.
These days, you can expect to pay less than $500 for a complete DNA profile, including Y-chromosome genetic testing and mitochondrial DNA testing.
Women have two X chromosomes and men have an X and a Y chromosome.
The sperm carries either another X or a Y chromosome.
The male sperm contains either an X or Y (the Y chromosome makes a male).
