Question

Research a mutation found on the X chromosome, determine whether it is X-linked

dominant or X-linked recessive, and consider how the probability of passing on the trait
changes depending on the sex of the carrier and the sex of the carrier's offspring (for
example, investigate an X-linked mutation like Rett syndrome and determine how being X-
linked dominant affects the ability to pass the condition on to female and male offspring.

Answer 1

X-linked disorders can be dominant or recessive, and the probability of passing on the trait depends on the sex of the carrier and the sex of the carrier's offspring.

Step-by-step explanation:

X-linked Dominant or Recessive Inheritance

An X-linked transmission pattern involves genes located on the X chromosome of the 23rd pair.

Human males need to inherit only one recessive mutant X allele to be affected, so X-linked disorders are more commonly observed in males. Females must inherit recessive X-linked alleles from both parents to express the trait, but they can be carriers of the trait and are typically unaffected.

Carrier females can pass the trait to their sons, resulting in the son exhibiting the trait, or they can pass the recessive allele to their daughters, resulting in the daughters being carriers of the trait.
