1. why don’t people have mutations in the telomerase gene that affect phenotype?
2. severe childhood autosomal recessive muscular dystrophy prevalent in North Africa, affects both sexes and is caused by a deficiency of a dystrophin-associated glycoprotein called adhalin. How mutations in two different genes — those for dystrophin and adhalin — can cause the same symptoms for muscle wasting.
1. I’m sure they do have mutations, but perhaps your teacher is looking for an answer involving premature or postponed aging.
2. Those two proteins must both make muscles, and/or make muscles work.
