Which two genotypes in an individual would be expressed as the same phenotype in a diploid organism?

The correct answer is - h0m0zygous dominant and heterozygous .

Explanation:

The h0m0zygous dominant which means genotype with two copies of the particular gene, and heterozgyous genotype which means genotype with one copy of dominant allele and one allele recessive allele has the same phenotypic expression in a diploid organism.

In h0m0zygous dominant only dominant phenotype will be expressed and in heterozygous genotype the phenotype will be dominant.

Thus, the correct answer is - h0m0zygous dominant and heterozygous .

affects the water bodies: excessive use of fertilizers causes eutrophication. the fertilizers which are used on plants affect the quality of land on which it is used, further causing erosion of soil. the fertilizers used on plants contain harmful chemical fumes which affect the environment.
