About 16% of the population in the United States has Rh-blood typeThe Rh-blood type occurs in individuals who are homozygous recessive for the Rh allele. What percent of the population would be predicted to be homozygous dominant for allele?

p² = 0.36 or 36%

Explanation:

Using the Hardy-Weinberg equation to solve this problem:

The basic equation is as follows:

p + q = 1.0 where p and q are the allele frequency and it is always equal to 1.

There are different variations for calculating the homozygous and heterozygous variations if deeper detail, but for this question we will stick to the basic equation for simplification purposes:

If the homozygous recessive is 16% then q²= to 0.16

This means that q is equal to 0.4

If q is equal to 0.4 then p is equal to 1.0-0.4

p is equal to 0.6

This makes p²=.36 or 36%

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.
