Question

Where are Y-linked genes located, and what is their inheritance pattern?

विकल्प

• On both X and Y chromosomes and are inherited equally by all offspring

• On autosomes and are inherited by daughters only

• On the X chromosome and are passed from mother to all offspring

• On the Y chromosome and are passed directly from father to son

Answer 1

Y-linked genes are located exclusively on the Y chromosome. Since only males possess a Y chromosome, Y-linked genes are transmitted directly from father to son in an uninterrupted patrilineal pattern, with no possibility of transmission to daughters.
