Answer 2

The correct answer is option d) Phenotype.

The physical characteristics of an organism is included in phenotype. This is becuse of the folowing points :

• An individual’s phenotype is the combination of their observable characteristics or traits.
• Phenotype is merely influenced by genotype.
• Environmental factors can also affect phenotype.

Option a) Gene is incorrect because :

• Gene is the basic unit of heredity passed from parent to child.
• Genes are made up of sequences of DNA and are arranged, one after another, at specific locations on chromosomes in the nucleus of cells.

Option b) Allele is incorrect because :

• One of two or more DNA sequences occurring at a particular gene locus is called allele.
• All the alleles found in an organism make up the genotype.
• If a pair of alleles are similar, the organism’s genotype is called homozygous.
• If the pair of alleles are different, the organism’s genotype is called heterozygous.

Option c) Genotype is incorrect because :

• An individual’s genotype is the combination of alleles that they possess for a specific gene.
• An organism’s genotype is directly inherited from its parents.
