MCQ
When two individuals are similar in external appearance but differ in their genetic make $-$ up, they are said to have the same :
- ✓Phenotype
- BGenotype
- CHomozygous
- DBoth $A$ and $C$
✓
Answer
Correct option: A.
Phenotype
The characters of an organism that are visible are known as phenotypes and a genotype is defined as the unique genetic constitution of a living organism.
Now, the same phenotype may or may not belong to the same genotype.
As an example, the genotype of a tall plant can be $\ce{(TT)}$ or $\ce{(Tt)},$ but phenotypically both the genotypes will produce tall plants.
A homozygous genotype may include two normal alleles or two alleles that have the same variant.
