3. mThe mnurse mis mteaching ma mcouple mabout mX-linked mdisorders mbecause mthey mare mconcerned
mthat mthey
might mpass mon mhemophilia mto mtheir mchildren. mWhich mresponse mindicates mthe mneed mfor

A. m"The mfather mcan't mbe ma mcarrier mif mhe mdoesn't mhave mhemophilia."
B. m"If mthe mfather mdoesn't mhave mit, mthen mhis mkids mwon't meither."

D. m"If mthe mmother mis ma mcarrier, mher msons mwill mhave mhemophilia." m- mAnswer m- mAnswer: mB
Rationale: mMales mare mmore maffected mthan mfemales. mA mmale mhas monly mone mX mchromosome,
mand mall
the mgenes mon mhis mX mchromosome mwill mbe mexpressed mwhereas ma mfemale mwill musually mneed
mboth mX

A. mDown msyndrome
B. msickle-cell manemia
C. mcardiac mdefects
D. mrespiratory mdisorders m- mAnswer m- mAnswer: mA

A. mduring mmeiosis mcell mdivision
