Question

8.5. compare and contrast the inheritance of recessive, dominant, and sex - linked genetic disorders. complete the passage. complete the passage by filling in the blank(s). drag the word(s) below to fill in the blank(s) or use your keyboard to choose word(s) from the dropdown menus. some genetic disorders are said to “skip a generation,” but they are present in a parent, known as a carrier, who has a copy of the allele for the disorder that is masked by another allele. the only disorders that cannot be inherited in this way are autosomal dominant. in disorders that are sex - linked, only one parent, the blank, can pass on the disorder without expressing it. autosomal recessive mother father enhanced

Explanation:

In sex - linked genetic disorders, the mother can be a carrier and pass on the disorder without expressing it because she has two X chromosomes. If she is heterozygous for the sex - linked trait, the recessive allele can be passed on to offspring. Fathers have only one X chromosome, so if they have the allele for a sex - linked disorder, they will express the disorder. Autosomal recessive disorders can skip generations as carriers exist, and autosomal dominant disorders do not skip generations as the presence of one dominant allele causes the disorder to be expressed.
