Two organisms have the same phenotype but different genotypes when One organism is purebred dominant, and the other organism is heterozygous. So, the correct option is B.
<h3>What do you mean by Genotype?</h3>
Genotype may be defined as the ultimate combination of those alleles which are selected for specific studies.
When an allele is dominant over others, its purebred dominant and heterozygous (hybrid) may have different genotypes but the same phenotype.
Therefore, the correct option for this question is B.

The percentage of progenies with red eyes and spine will be 56.25%.
<h3><u>Explanation:</u></h3>
This cross will be just similar to Mendel’s Dihybrid cross where he crossed the pea plants considering two characters at once.
Here two characters that are taken into account are eye colour and presence of spine. The eye colour has two traits - red and brown. Red colour is dominant. The presence of spine has also two possibilities - presence of spine or absence of spine.
The allele denoting red eye colour is R and allele denoting brown eye colour is r. Similarly, the allele denoting presence of spine is S and absence of spine is s.
Genotype of the heterozygous parents = RrSs.
Gametes produced by the parents= RS, Rs, rS and rs.
So crossing them, we get the phenotypic ratio of red eyed spined : red eyed spineless : brown eyed spined : brown eyed spineless = 9:3:3:1.
So, the percentage of red eyed spined = 56.25%.

Explanation:
Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells.
