Multiple Choice
For the sake of this genetics problem,consider that right-handedness (RR,Rr) is dominant to left-handedness (rr) .A teacher surveys her class of 24 students and finds that six (one-fourth,or 0.25) are left-handed.How many of the remaining right-handed students are likely to be carriers for a left-handedness gene?
A) None, they will all be RR for right-handedness since a dominant gene dominates
B) Six, same number as are left-handed or 0.26 x 24
C) Twelve, since q2 = 0.25, then q = 0.5, and 2pg or 2(0.5 x 0.5) = 0.5 of a class of 24
D) Eighteen will be Rr since 24 - 6 = 18
