Which of the statements below regarding X-linked inheritance of a recessive trait is FALSE?

Question

a. Heterozygous females will transmit each X- linked allele to about half of their daughters
b. Males inheriting an X-linked allele have the trait
c. The trait would be more common in females
d. Heterozygous females will not display the trait

Answer 1

c. The trait would be more common in females (This is false because X-linked recessive traits are more common in males. Females have two X chromosomes and would need to inherit two copies of the recessive allele to display the trait, while males only need to inherit one.)
