ReneTo determine if a child has an extra half of a chromosome, genetic testing such as a chromosomal microarray analysis or a karyotype test would be needed. These tests can identify any abnormalities in the number or structure of chromosomes in an individual's cells. It is important to consult with a healthcare professional or a genetic counselor for proper diagnosis and guidance.

What genetic material do you get from your mother?
If you are female, you receive half of your father's genetic material. If you are male, you receive almost half; the Y chromosome is missing some genes, so it is the mother's X chromosome and the genes on the top of it that solely determine certain characteristics in the son. These are called sex-linked characteristics.
If a trait is always transmitted directly from a father to all his sons and from those sons to all their son what chromosome would the gene for the character be likely on?
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.
Who does a male child inherit his X chromosome from?
yes, some people have xxy chromosomes, a genetic mutation. Although I'm not sure if the extra chromosome is from the fathers sperm or sex cell. Hope this helps :)
Y linked genes are passed only from who?
Y-linked genes are only passed from father to son because the Y chromosome is inherited exclusively in a paternal manner. Since females inherit an X chromosome from each parent, they do not receive a Y chromosome from their father.
A woman is a carrier for hemophilia what is the chances for sons with hemophilia if the father does not have hemophilia?
If the mother is a carrier for hemophilia, there is a 50% chance that her sons will inherit the hemophilia gene, but only if the father does not have hemophilia. This is because sons inherit the X chromosome that carries the hemophilia gene from their mother. If the father does not have hemophilia, the son will not inherit a healthy X chromosome from him to compensate for the defective X chromosome from the mother.
