can someone help with this? the answer choices are sex-linked or autosomal for the first one, and dominant or recessive for the second

sex-linked and recessive

Explanation:

A pedigree chart is a genetic representation that exhibits the phenotypes and genotypes for a genetically inherited trait (usually a disease or condition) in a family tree. In this case, the trait in the pedigree is recessive and linked to sex (X chromosome-linked) because it can occur only in males who receive the X chromosome for this condition from their mothers, while females can be carriers that don't have the disorder but can pass it on to offspring.
