If a cross is made between two parental homozygous allele female Red phenotype  (RR) cross with male white phenotype (rr)  resulting F1 progeny  is all red phenotype (Rr), if reciprocate this cross the resulting progeny will be change.

a) Gene expression will be the parental origin dependent

b) uniparental gene contribution and also the expression of the gene is uniparental

c) Gene expression independent over parental origin

d) Gene contribution is biparental but the expression of the gene is uniparental

This prediction concludes that,
