Question
Heredity totally determine an individual's :
(i) Sex
(ii) Gender
(iii) Academic Success
(iv) Learning Style
The correct answer is
(i)
Heredity's Influence on Individual Traits
This question asks us to identify which characteristics among Sex, Gender, Academic Success, and Learning Style are totally determined by heredity. Heredity refers to the genetic inheritance and the passing of traits from parents to offspring via genes.
Understanding Heredity and Trait Determination
Let's analyze each factor:
- (i) Sex: Biological sex is primarily determined by chromosomes inherited from parents. Typically, females have XX chromosomes and males have XY chromosomes. This genetic basis means that sex is largely, and in many contexts considered totally, determined by heredity.
- (ii) Gender: Gender encompasses identity, expression, and social roles. While biological sex (influenced by heredity) plays a part, gender is significantly shaped by social, cultural, psychological, and personal factors. Therefore, gender is not totally determined by heredity.
- (iii) Academic Success: Academic success is a complex outcome influenced by many factors. While intelligence and certain aptitudes might have a hereditary component, factors like quality of education, socioeconomic status, motivation, environment, and personal effort play crucial roles. Heredity alone does not totally determine academic success.
- (iv) Learning Style: Learning styles describe how individuals prefer to learn. These preferences are influenced by cognitive abilities, past experiences, personality, and environment. While some cognitive abilities might be influenced by heredity, learning styles themselves are not totally determined by genetics alone.
Conclusion on Hereditary Determination
Based on the analysis:
- Sex (biological sex) is predominantly determined by inherited chromosomes.
- Gender, Academic Success, and Learning Style are influenced by a combination of heredity and environmental/social factors.
Therefore, among the options provided, only 'Sex' is considered to be totally determined by heredity.
