Final answer:

The trait described is likely an X-linked recessive trait, which can result in unaffected parents having an affected son if the mother carries the recessive allele on one of her X chromosomes.

Step-by-step explanation:

The question describes a situation where non -affected parents can have an affected offspring , and this trait has the potential to skip a generation. These characteristics strongly suggest that the trait in question is likely an X-linked recessive trait. In the context of genetics, X-linked refers to genes that are present on the X chromosome, but not the Y chromosome. Since males have only one X chromosome, a recessive trait can be expressed with just one copy of the recessive allele, thus affecting them. Females, having two X chromosomes, need two copies of the recessive allele to express the trait. Consequently, it is possible for unaffected, heterozygous (carrier) parents to have an affected son if the mother passes the affected X chromosome to him. An example of an X-linked recessive trait is color blindness.
