Detailed Solution

Law of segregation is universal. There is no exception to this law.

As the dominant colour is not expressed in $F_{1}$ generation we can say that the principle of dominance is not followed.

An intermediate phenotype is expressed in $F_{1}$ generation which is because of incomplete dominance.

When we do selfing of $F_{1}$ generation the genotypic ratio of $F_{2}$ generation is 1 /4 RR, 2/4 Rr, 1 /4 rr.
