Answer 1

b. Red is a dominant trait, and blue is a recessive trait.

Step-by-step explanation:

Since red flowers appear in the majority of plants, they are dominant, as their phenotype red flowers are expressed the most frequently. However, since blue flowers appear in only a few plants, it is expressed less frequently and is less common, so it is suppressed by a dominant allele, making blue flowers recessive.
