In sweet peas,the allele C is needed for color expression (c results in white).The precise color expressed is determined by the alleles R (red)and r (blue).A cross between certain red and blue plants resulted in progeny as follows: 3/8 red,3/8 blue,1/4 white.What were the genotypes of the plants crossed?
A)\ C/c;R/r $\times$ C/C;R/R
B)C/c;R/r $\times$ C/c;R/r
C)C/c;R/r $\times$ C/c;r/r
D)C/c;R/r $\times$ c/c;R/r
E)C/c;r/r $\times$ C/C;R/r
