Ans.
Sex-linked genes are those genes that found on sex-chromosomes (X and Y chromosomes) and their phenotypic expression for a trait depends on the gender of the offspring.
Most of the sex-linked genes are present on X chromosomes as X chromosomes have more number of genes as they are made up of more DNA as compared to Y chromosome.
However, male individuals are more likely to exhibit the sex-linked traits. It is because most of the sex-linked traits are recessive and males have only one copy of X chromosome, while females have two copies of X chromosome. One mutated copy in male can exhibit the trait, while in females, both of the mutated copies are required to exhibit that trait.
I believe the correct answer is - <span>This drug helps people lose more weight than diet and exercise alone.
It says here in the text - 48% of the people who took these drugs along with exercise and diet lost weight, whereas only 23% of those who had exercise and diet (but no drug) lost weight. Obviously, this shows that more people who took the drug lost weight than those who didn't.

Xylem is the answer......
