Why is human Y chromosome a marker for only the paternal and not the maternal human genetic lineage?

Because XY denotes male. The SRY region is on the Y chromosome. This is the sex determining region, males are made and females are the default condition in humans.

What is a hybrid gene?
A hybrid gene is a gene that is formed from a combination of two different genes. It can be made by recombinant DNA technology. Hybrid genes possess at least one characteristic of both the genes combined.
1 Why is the Y chromosome particularly useful for tracing human genetic history?
It is only passed from father to son, so it provides a direct lineage. If a person is discovered to have a unique marker, you know that everyone else in the world that has that marker is descended from that one person.
The genetic material that carries information needed to make new cells or new organisms?
DNA is the genetic material that carries the information needed to make new organisms or new cells within organisms. The DNA in mitochondria is only from the individual's maternal lineage, versus the individual's unique DNA found in other cells.
How does DNA affect parent's offspring?
If a parent has a mutation and survives and reproduces, it's offspring will also have that genetic mutation, and over time, if the animals with the mutation survive, the whole species will have the mutation. This is called evolution.
Is genetic disease means the same as genetic predisposition?
Genetic Predisposition is a genetic effect which influences the phenotype of an organism but which can be modified by the environmental conditions. Genetic testing is able to identify individuals who are genetically predisposed to certain health problems.
What is the purpose of genetic genealogy?
Genetic genealogy used DNA testing to determine the level of relationship between two individuals. It is used to find out if people share genetic realtions either a brother or sister and to find out the paternal or maternal lineage of a given person.

What is the antonym of the following terms-parental-paternal-maternal-family-ancestral-linear-patriarchal-collateral-descent?
ANTONYM FOR LINEAGE;THE ANTONYM FOR LINEAGE IS DESRUCTION because lineage means almost generation and that antonym is destruction!
What is my maternal grandfather's side of the family called?
Your maternal grandfather's side of the family is referred to as your maternal grandfather's lineage or maternal grandfather's family.
Why is Chuck Norris one eighth Cherokee?

Is Simon cowell protestant?
Yes. Raised an Anglican with some ethnic jewish lineage on his paternal side
What is materilineal?
You might be referring to matrilineality, which is a system in which lineage is traced through the mother and maternal ancestors. (Wikipedia)
Can you use chromosome maps to produce a pedigree?
Yes, you could generate lineage maps.
