One form of polycystic kidney disease (PKD) has an autosomal-dominant transmission pattern. Explain the following:- Describe how autosomal dominant and autosomal recessive traits are alike.- Describe how autosomal dominant and autosomal recessive traits are different.- Why does a 60-year-old man with the disease still have about 25% kidney function remaining, but his monozygotic twin daughters had such severe disease that they each had to have a kidney transplant by age 18 (assuming that all three of them had very good care and were very adherent to their medical regimens).
