Complete Practice Problem 20 on page 615 in the textbook. Identify the phenotypes and genotypes of all the people shown in this pedigree. Rolling the tongue (R) is dominant over inability to roll the tongue as it remains flat (r).


Hint: What kind of inheritance is this? How do you assign symbols? See (sr) Pedigree Analysis. Did you assign all non-shaded individuals first, (recessive)?
Did you start at the bottom and work upwards through the genotypes of generations?
What kind of twins are symbolized in the chart?
Correct: Fraternal twins. Is it possible to have fraternal girl twins?
Yes.
