Keeping biological determinants in perspective, consider the following statements:
1. Presence of a normal karyotype is the first requisite for human health
2. Genetic screening can play an important role in prevention of wide spectrum of diseases
3. If an individual is allowed to live in healthy relationship with the environment, the
person's genetic potentialities can transform into phenotypic realities
Which of the above statements is/are correct?
This question requires evaluating three statements related to biological factors influencing human health.
Presence of a normal karyotype is the first requisite for human health
A normal karyotype, representing the standard set of chromosomes, is fundamental for typical human development and function. Chromosomal abnormalities often result in significant health issues or developmental disorders. Thus, it is a foundational biological requirement for health.
Genetic screening can play an important role in prevention of wide spectrum of diseases
Genetic screening methods help identify predispositions to various diseases, carrier statuses, or genetic mutations. This information is vital for implementing preventive strategies, early interventions, and informed reproductive choices, contributing to the prevention of many diseases.
If an individual is allowed to live in healthy relationship with the environment, the person's genetic potentialities can transform into phenotypic realities
This statement addresses the genotype-environment interaction. Genetic potential (genotype) requires appropriate environmental conditions to be fully expressed as observable characteristics (phenotype). A healthy environment supports the optimal realization of genetic predispositions.
All three statements accurately describe key concepts in human biology and genetics:
Therefore, statements 1, 2, and 3 are all correct.
Which of the following statements regarding Physical Quality of Life Index (PQLI) are correct?
1. It consolidates infant mortality, life expectancy at age one, and literacy
2. It does not measure economic growth but measures the result of economic policies
3. For each component, the performance of individual countries is placed on a scale of 0-100
