Organisms phenotypically similar but genotypically different are said to be:
Correct answer: C. Heterozygous
- A. Monozygous
- B. Homozygous
- C. Heterozygous
- D. Multizygous
Explanation
Heterozygous organisms possess two different alleles for a specific trait, which allows them to exhibit similar phenotypes (observable characteristics) despite having different genotypes (genetic makeup). This is why they are phenotypically similar but genotypically different. The other options are incorrect because:Monozygous: Relates to organisms from a single zygote and does not address phenotypic or genotypic differences.Homozygous: Implies both phenotypic and genotypic similarities due to identical alleles.Multizygous: Is not a recognized term relevant to the concept of phenotypic similarity and genotypic difference.

About Mendel's Laws of Inheritance
Mendelian inheritance explains how alleles separate into gametes and assort during reproduction, producing predictable genotype and phenotype ratios. Questions cover dominance, recessiveness, homozygous and heterozygous conditions, the laws of segregation and independent assortment, monohybrid and dihybrid crosses, test crosses and the limits caused by linked genes.
