We can better understand it with the help of examples. Red flower - RR, white - rr Offspring - Rr In complete dominance - phenotype all red flowers, as red is completely dominant over white allele. In incomplete dominance- no complete dominance if any particular gene over the other. So in between of two phenotype we get a phenotype of pink colour and neither red not white. If Rr×Rr in complete dominance RR- red, 2Rr- red, RR- white. Hallo sufficiency as one copy of gene is enough to maintain the character. In incomplete dominance- RR- red, 2Rr- pink, RR- white. Haploinsufficiency as one copy if gene is not sufficient to maintain the character. Solution We can better understand it with the help of examples.
