Codominance

Explanation:

Codominance is a pattern of inheritance when none of the alleles of a gene is dominant over the other allele of the same gene. When present together in a heterozygous genotype, both the alleles are able to express themselves. In the given example, a cross between blue and yellow flowered plants obtained the progeny with blue and yellow speckled flowers. Here, the alleles of blue and yellow flower color are codominant and express themselves in the hybrid progeny.
