Question

match each type of genetic disorder to the potential carrier or carriers. a parent of either genetic sex can be a carrier. there are no carriers for this type of disorder. only parents who are genetically male can be carriers. only parents who are genetically female can be carriers. autosomal recessive autosomal dominant sex - linked

Explanation:

• Autosomal recessive: A parent of either genetic sex can be a carrier. In autosomal recessive inheritance, an individual needs two copies of the recessive allele (one from each parent) to express the disorder. So, parents can be carriers (heterozygous) without showing the disorder.
• Autosomal dominant: There are no carriers for this type of disorder. In autosomal dominant inheritance, if an individual has one copy of the dominant allele, they will express the disorder. So, there is no "carrier" state (where the individual doesn't show the disorder but can pass it on) like in recessive disorders.
• Sex - linked: Only parents who are genetically female can be carriers. Sex - linked disorders (usually X - linked) are carried on the X chromosome. Males have one X and one Y chromosome (XY). If a male has a recessive allele on his X chromosome, he will express the disorder (since there's no second X to mask it). Females have two X chromosomes (XX). A female can be a carrier (heterozygous, with one normal and one recessive X - linked allele) without showing the disorder.

Answer:

• Autosomal recessive: A parent of either genetic sex can be a carrier.
• Autosomal dominant: There are no carriers for this type of disorder.
• Sex - linked: Only parents who are genetically female can be carriers.
