WebUsing a similar Punnett square for the parents' fur texture alleles, the probability of getting an Cc genotype is also 1 / 2 1/2 1 / 2 1, slash, 2. To get the overall probability of the BbCc genotype, we can simply multiply the two probabilities, giving an overall probability of 1 / 4 1/4 1 / 4 1, slash, 4 . WebNow what co-dominance is, is when the heterozygous phenotype shows a flower with some red petals and some blue petals. So it's when the two alleles are dominant together they are co-dominant and traits of both alleles show up in the phenotype. Now what incomplete dominance is, is when the heterozygous phenotype shows a mixture of the two alleles.
