Question

Genetic constitution of an individual is represented by
A. Genome
B. Genotype
C. Phenotype
D. Karyotype

Answer 1

Hint: Genetic constitution of the individual is also named as genetic makeup, genetic composition etc. These are the specific alleles present at the specified loci in an individual. It is the genetic makeup of a cell, individual or an organism regarding certain features under consideration.

Complete answer:
The genotype usually represents the genetic makeup or the unique combination of Gene's of an individual. Hence, the complete set of instructions of the synthesis of protein by the body of an individual and the way of building and developing as well as the function of the body. Examples of genotype include:
> A gene encoding colour of the eye and hair
> A gene encoding the height
> A gene encoding shoe size.
The phenotype is the sum of the observable characteristics or features of an organism. It is the actual structure and the function of the individual's body. The phenotype may get affected by the environmental factors which include temperature, humidity, stress and nutrition.
The resemblance of the full set of chromosomes in the cells of an individual is referred to as karyotype.

Therefore, the correct option is (B) Genotype.

Note:
The student might get confused between the genome and genotype as they are considered similar in many places. A genome is a complete set of DNA that comprises all of its genes in an individual or organism. While the genotype is the successive combination of alleles that are possessed by an individual for a particular gene. The phenotype of an organism or individual is given by the expression resulted by the genotype.
