A gardener crosses a true-breeding tall tomato plant bearing red fruit with a true-breeding dwarf tomato plant with yellow truit. In tomatoes, tall vine (T) is dominant to dwart vine (t) and red fruit (1) is dominant to yellow fruit (1)
Assume that the two genes controlling the “tali vine“ and “red fruit" traits are on two different pairs of chromosomes.
What are the expected phenotype ratlos in the F2 generation?
A 9 tall vinatred fruit; 3 tal vine/yellow truit; 3 dwart vine/red fruit: 1 dwarf vine/yellow trult
B. 4 tall vine/red fruit, 3 tali vine/yellow fruit; 1 dwarf vinetred fruit

i don't understand your question

answer;

a. sheep consumption efficiency would be reduced.

explanation;

-trophic efficiency is a measure of how much energy occurs at one level divided by the energy at the level immediately below it . trophic efficiency incorporates three types of efficiency:

-the proportion of available energy that is consumed (consumption efficiency).   it is the proportion of the available biomass that is ingested by consumers.

-the proportion of ingested food that is assimilated (assimilation efficiency).

-the proportion of assimilated food that goes into new consumer biomass (production efficiency).

-in this case, the grasshoppers would affect sheep by reducing the proportion of the available biomass that is ingested by the sheep.
