An individual who is a "carrier" for a sex linked trait like hemophilia:?

Question

a. is always female.
b. Is heterozygous for recessive condition.
c. shows the dominant phenotype.
d. can pass the gene on to his/her daughters.
e. All of the above choices are correct.

Answer 1

E. Carriers have one dominant gene and one recessive (so b is true). Therefore they show the dominant phenotype (so c is true) Sex-linked traits are always carried on the X chromosome. Since men have only one X chromosome, they either have the trait or not--they can't be carriers (so a is true). And a parent can always pass any of his/her genes on to his/her daughters (unless the trait were encoded on the y chromosome, but as far as I know, none are). So d is also true.

Answer 2

E. all are correct
