For the Sake of This Genetics Problem,consider That Right-Handedness (RR,Rr)is

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 0.25 * 24
C) Twelve,since q2 = 0.25,then q = 0.5,and 2pq or 2(0.5 * 0.5) = 0.5 of a class of 24
D) Eighteen will be Rr since 24 - 6 = 18
