Answer:

If the trait is X-recessive

Explanation:

X-recesssive trait means that that the gene causing the trait or the disorder is located on the X chromosome and that  alleles of that gene must be recessive. In females (XX chromosomes), alleles of both chromosomes must be recessive so that the trait can be expressed. On the other hand, in males (XY chromosomes), only one recessive allele is sufficient for the trait expression.
