__________ genes are transmitted only through as they are present on the y chromosome.​

Answer 1

The Y chromosome contains a "male-determining gene," the SRY gene, that causes testes to form in the embryo and results in development of external and internal male genitalia. If there is a mutation in the SRY gene, the embryo will develop female genitalia despite having XY chromosomes.

The human Y chromosome carries an estimated 100-200 genes, with between 45 and 73 of these protein-coding. All single-copy Y-linked genes are hemizygous (present on only one chromosome) except in cases of aneuploidy such as XYY syndrome or XXYY syndrome.
