Why isn't MT DNA talked as much as Y DNA?

Wrong again, your maternal ancestry cannot be same because almost every woman has different mtdna.

People get their MT DNA directly from their mother. I do not know what my MT DNA is but it would be the same as my mother and my maternal grandmother.

No because your mother and your grand mother came from totally different family. Your mtdna is same with your mother's mtdna that's all.

And my mother's mtdna is the same as her mother.

Do we?

yep about twice as many, seems paradoxical but think about it for a bit

I think it is equal a person is born from one male and one female.

Besides the rest of answers, it's "patriarchal instinct" forefather of tribes>clans>smaller families, it's the equivalent surname of DNA.

Absolutely not. For example if my grandmother was H3, if my grandfather was I1 than my father would be I1 + H3 later he make a baby with another woman (H5) than this baby would be I1 + H 5 and not H3.

MtDNA Haplogroups work the exact same way. If your father was an I1 then so was his father, and his father's father, and his father's father'sfather etc. If your mother was H5 then so was her mother, and her mother's mother, and her mother's mother's mother etc. The parallel to your example would be this: If your maternal grandmother was an H5 and your maternal grandfather was an R1b, then your mother would be an H5. If she later had a son and a daughter with your father, who's Y haplogroup is I1 and Mt haplogroup is H3, the son would be an I1 and H5 while the daughter would only be an H5. Your daughter would also be an H5.

To answer OP, Dorian is right. The reason is patrilineality.

LOL NO

My mother's haplogroup isn't same as my grand mother's haplogroup from father side because my mother is not a daughter of my father's mother (but she came from a different family with different mtdna) and the child's mtdna is always came from his/her mother. So my mtdna is not same as my grand mother from father side. I've talked about this.
