The combination of alleles at specific gene locations on an organism's chromosomes, representing its genetic constitution, is known as ______.

Correct option is C

The correct answer is (c) genotype

Explanation:

The genotype refers to the genetic makeup of an organism, specifically the combination of alleles (alternative forms of a gene) at specific gene locations on its chromosomes. This genetic constitution is responsible for the organism's inherited traits. It is different from the phenotype, which refers to the observable physical traits of the organism, such as its appearance or behavior, influenced by both genotype and environmental factors.

Information Booster:

• Genotype represents the underlying genetic code that determines an organism's characteristics.

• The genotype can be homozygous (same alleles) or heterozygous (different alleles) at a gene locus.

• The phenotype is the expression of the genotype, influenced by environmental factors.

• Mendelian inheritance studies how genotype influences phenotype through dominant and recessive alleles.

• The study of genotypes helps in understanding genetic diseases and traits.

• DNA carries the genetic information but the genotype refers to specific combinations of alleles within the DNA.

Additional Information:

• Phenotype – Refers to the observable characteristics or traits of an organism, shaped by the genotype and environmental factors.

• Double helix – Refers to the structure of DNA, not to the genetic makeup of an organism.

• DNA – Is the molecule that carries the genetic instructions, but the genotype refers to the combination of genes present in the organism.
