Explain what terms in the Hardy-Weinberg equation give: allele frequencies (dominant allele, recessive allele, etc.) each genotype frequency (homozygous dominant, heterozygous, etc.) each phenotype frequency

Explanation:

Hardy Weinberg equation is presented below and describes that in a population the frequency of alleles ad genotypes will remain static or the same in the absence of evolutionary disturbances such as mutation, migration ( gene flow), natural selection and with the population large and random mating

p² +2pq + q²

where p represents the frequency of the dominant alleles

q represent the frequency of the recessive alleles

p² represent the frequency of the dominant homozygous genotype

q² represent the frequency of the recessive homozygous genotype

2pq represent the frequency of the heterozygous genotype

q² also represent the frequency of the recessive phenotype

(p² + 2pq) represent the frequency of the dominant phenotype

Hardy Weinberg equilibrium states that in a population the amount of genetic variation remains constant from one generation to another generation in the absence of evolutionary disturbances.

They Hardy-Weinberg equation is:

p² +2pq + q² = 1

p       =  dominant alleles frequency (A)

q       =  recessive alleles frequency (a)

p²     =  dominant homozygous genotype frequency (AA)

q²     =  recessive homozygous genotype frequency (aa)

2pq  =  heterozygous genotype frequency (Aa)

p² and 2pq =  dominant phenotype frequency (A)

q²     =  recessive phenotype frequency (a)

Note: A or a is for example in which A represent the dominant allele while a represent the recessive allele.

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.
