Detailed explanation-1: -If a male who has an X-linked condition has a daughter, he will always pass on the changed gene to her. This is because males only have one X chromosome and they always pass this on to their daughters.
Detailed explanation-2: -Sons will be affected if they inherit the mutated X-linked gene from their mother. Fathers cannot pass X-linked recessive conditions to their sons.
Detailed explanation-3: -Biologically female people inherit an X chromosome from their father, and the other X chromosome from their mother. Biologically male people always inherit their X chromosome from their mother.
Detailed explanation-4: -The mother gives an X chromosome to the child. The father may contribute an X or a Y. The chromosome from the father determines if the baby is born as male or female.
