Question

if a male is affected by a recessive genetic disorder, what chromosome carries the trait? both x and y the y chromosome the x chromosome

Explanation:

Males have the sex - chromosome combination \(XY\). Recessive genetic disorders are often X - linked. Since males have only one \(X\) chromosome (and one \(Y\) chromosome which does not carry most of the genes related to these recessive disorders), if a male is affected by a recessive genetic disorder, the trait is carried on the \(X\) chromosome. The \(Y\) chromosome has very few genes in common with the \(X\) chromosome for these types of recessive disorders, and having both \(X\) and \(Y\) carry the trait for a recessive disorder in males is not typical for the common recessive genetic disorders (as \(Y\) does not have the corresponding alleles in most cases).

Answer:

the X chromosome
