Across involving true-breeding, red snapdragons and true-breeding, white snapdragons produce all pink offspring because both genes are present, neither over the other resulting in of the trait.

The correct answer for the blanks are- 1) Dominant and 2) Blending of the trait.

Incomplete dominance produces a blend/ intermediate phenotype of both the parental phenotypes ( such as Pink snapdragon here) because none of the parental allele completely masks the effect of other.

As per the given information in the question, when true-breeding, red snapdragons are crossed with true-breeding white snapdragons, they produce pink colored offspring. This means that neither of the parental gene is dominant over the other.

When both are cross bred, they will represent a heterozygous state ( when alleles for both the snapdragons are present ), and they will produce an intermediate phenotype ( that is a blend of both the traits). This represents blending of the parental trait.

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.

the answer is c.mitochondria. glad to .
