The cross of these two faces produces an offspring. If the alleles for color show incomplete dominance in the alleles for eye shape or codominant, what will the offspring look like

d) A cross of two true-breeding mice of different colors to look for an intermediate phenotype in the F1

To use an example in flowers, R = red and r = white. Since the parents are true breeding, the genotypes of the parents would have to be RR and rr. If the alleles are incompletely.
