Question

Study of genetic composition of population in relation to habitat is called
A. Genecology
B. Genetics
C. Eugenics
D. Euthenics

Answer 1

Branch of ecology which deals with the study of genetic variations of species, its genetic variants and their relationship with environmental factors.

Complete answer:

Genecology- It is the study of genetic compositions of the population in relation to their habitat.
Genetics- It is study of heredity, genes, variations of inherited characters.
Eugenics- It is a philosophy and social movements which aimed at improving the genetic composition of the human race by selective breeding
Euthenics- It is improvement of human functioning and their well being by improving the lifestyle or the external factors mainly.

So, from the options and the explanation given above. It is clear that Option C and D is completely incorrect and from option A and B, Option A is the correct one which is genecology as study of genetic composition of population in relation to the habitat is known as genecology. But genetics is the study of genes and heredity not the study of genetic compositions. This shows that the correct option is option A which is genecology

Hence, the correct answer is option (B).

Additional information:
Genecology is closely related to ecogenetics but it focus primarily on ecological perspective for looking at the change and interaction in species but the genecology focuses more on the genetic responses of the species to the environment.

Note: Study of heredity is called as genetics, study of philosophy and social movements is called as eugenics, Improvement of human functioning is called as euthenics and the study of genetic compositions is called as genecology and in the question, study of genetic compositions is asked which makes it the correct answer.
