2742. Sometimes a dominant allele may be carried on the X chromosome. In this case, the trait is sex-linked
AND dominant. The trait is handedness* and right-handedness is dominant to left-handedness AND the
genes for handedness are carried on the X chromosome. Cross a left-handed woman with a right-handed
man. HINT: make sure you define your symbols first!!
