Sons inherit recessive sex-linked traits primarily from their mothers. This is because males have one X and one Y chromosome (XY), while females have two X chromosomes (XX). If a mother carries a recessive allele on one of her X chromosomes, there is a chance she will pass that allele to her son, who will express the trait since he only has one X chromosome.

Why will a male inhert x liked recessive gene from is dad?
A male inherits his X chromosome from his mother and his Y chromosome from his father. Therefore, he cannot inherit an X-linked recessive gene directly from his dad, as fathers pass their Y chromosome to their sons. If a male has an X-linked recessive condition, it must come from his mother, who can pass on the affected X chromosome. In summary, males inherit X-linked traits only from their mothers.
Why can a man who has sex-linked disorder pass the disorder to his daughter but not to his sons?
Sex-linked disorders are passed on the X chromosome. The man supplies the Y chromosome to his sons so the disorder cannot be passed on to the sons. But the man gives his daughter an X chromosome so the disorder can be passed on to her.
Sex linked recessive disorder are most often passed from mother to sons?
true
Is recessive disorders mostly passed from mothers to sons?
No. Recessive genetic traits (not all are defined as disorders) can be passed from either parent.
A color-blind woman mates with a male with normal color vision Which of these results would indicate that color blindness is caused by an X-linked recessive allele?
If the couple has a color-blind son, it would indicate that color blindness is caused by an X-linked recessive allele. This is because sons inherit their single X chromosome from their mother, who carries the recessive allele for color blindness but does not express it due to her second X chromosome providing the normal color vision gene.
What is the pattern of inheritance for a sex-linked recessive trait in a pedigree?
In a pedigree, a sex-linked recessive trait is passed down from carrier mothers to affected sons. Daughters of carrier mothers have a 50 chance of being carriers themselves. Sons of affected fathers do not inherit the trait.
Why will a male inhert x liked recessive gene from is dad?
