How can you tell that these snapdragon do not follow the pattern of complete dominance

Thorough observation and understanding of dominance types

Explanation:

It is very simple to distinguish between traits following complete dominance or incomplete dominance

There can be three cases of dominance

a) Complete dominance - where characteristics of one allele are expressed over and above the characteristics of the other allele

b) Incomplete dominance - Here both the traits are dominant but a blending of the two traits occur  for example red and white flower producing pink flower

c) Co-dominance - Here both the traits are dominant but no blending occurs between the two traits occur  for example red and white flower producing flower with red and white bands

Based on the above definitions , pattern of complete dominance is followed or not in case of snapdragon can be depicted.
