When a trait is x-linked, a single recessive allele is sufficient for a male to be affected because he carries only one X chromosome

What do you mean a single recessive allele is sufficient for a male to be affected ?

Genetic disorders connected to mutations in genes on the X chromosome are referred to as having X-linked recessive inheritance. Because he contains just one X chromosome, a male who carries this mutation will be affected. A female with a gene mutation on one X chromosome but a normal gene on the other is typically unaffected.

  • Males are more frequently affected by X-linked recessive disorders. Men only possess one X chromosome. The disease is brought on by a single recessive gene on that X chromosome. The Y chromosome makes up the second half of the male XY gene pair.
