Mendel was in part able to formulate his Law of Independent Assortment because a. in those particular traits he first studied , their genes were not linked. b. the genes for the traits contained only two alleles. c. the traits were discrete. d. (a), (b) and (c) would apply.

A

Expin lanation: While he studied the traits, he discovered that the genes were independent showing no form of relationship at all.

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.
