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.

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

The Y chromosome is passed from father to son without genetic recombination with the mother's DNA during reproduction. This lack of recombination ensures that the Y chromosome remains largely unchanged over generations, making it a useful marker for tracing paternal genetic lineages. Meanwhile, the mother's mitochondrial DNA is inherited by all offspring, making it a marker for maternal genetic lineages instead.


What does gengology mean?

There appears to be a typo in your question. It is likely you meant "genealogy," which is the study and tracing of one's lineage and family history through the examination of historical records, genetic analysis, and other sources of information.


A what show patterns of genetic inheritance in a family?

A pedigree chart shows patterns of genetic inheritance in a family by tracing the transmission of genetic traits across generations. It displays relationships between family members and highlights any inherited traits or diseases.


What is the study of lineage called?

The study of lineage is called genealogy. It involves researching and tracing one's ancestors and their relationships through historical records, documents, and genetic analysis.


Which process occurred frequently in the early history of the three domains on Earth and makes determining phylogenetic relationships of that time difficult?

Horizontal gene transfer permits gene flow from one organism's genome to another organism's genome, It occurs commonly between prokaryotes of different species, and even between prokaryotes and eukaryotes.

Why is the y chromosome useful for tracing ancestry?

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.

Linkage studies refer to tracing a particular trait within a family does this mean that twin and adoption studies are a type of linkage study?

No. Linkage studies use markers to identify chromosomal regions that may be linked to disease. Twin and adoption studies establish heritability and thus the genetic basis of a disease, not which chromosome or chromosomal region may be implicated. For this reason they are called genetic epidemiological studies.

Can ancestry be wrong when tracing family history?

Yes, ancestry can be wrong when tracing family history due to errors in records, incomplete information, or mistaken identities. It is important to verify information through multiple sources to ensure accuracy in genealogical research.
