The inheritance of genetic traits from parents to children follows predictable rules. knowing that each parent contributes genes equal to each child what determines an inherited trait such as eye color

The correct answer is...

The interaction between dominant and recessive genes.

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.
