Question

The sum total number of all the individuals of a Mendelian population constitutes ……….
A. Gene frequency
B. Gene pool
C. Genome
D. Genotype

Answer 1

Hint:- A mendelian population is a group of interbreeding species that shares a common gene pool. Under such situations, the mendelian populations are defined by genetic inertia. If mutation, selection, certain changes in the choice of parent pairs and decrease in the size of the population occur, it does not cause any imbalance and the genetic structure of the population remains unchanged.

Complete step-by-step solution:- The ratio of a specific allele to the total of all the alleles of the similar gene present in a particular population is known as the gene frequency. Gene frequency refers to how common an allele is in a population. Gene frequency is interpreted by estimating how many times the allele arises in the population by dividing it with the total number of copies of the gene.
- The collective hereditary information contained within a community of sexually reproducing organisms is known as the gene pool. It is simply the total sum of the allelic gene content of a particular group.
- The genetic composition of an organism which contributes to the expression of the physical traits of an organism is known as the genotype.
The complete set of the genetic material of an organism is known as the genome.

The sum total number of all the individuals of a Mendelian population constitutes the Gene pool. So, the correct answer is option (B)

Note:-
Population genetics is a branch of genetics that explores the consequences of Mendelian inheritance at the level of populations rather than families. It is concerned with the dynamics of how populations evolve as a result of the propagation of genetic mutations occurring within the germlines of individuals.
