Summary
Adolescent students possess poor knowledge of human genetics and genetic disorders. Educational initiatives are crucial to improve awareness and early detection of genetic conditions.
Area of Science:
- Human Genetics
- Adolescent Health
- Public Health Education
Background:
- Adolescents (10-19 years) face risks from early marriage and pregnancy.
- Genetic disorders impact reproductive-aged individuals.
- Screening and history-taking can identify genetic risks during pregnancy.
Purpose of the Study:
- To assess the knowledge of school students regarding human genetics.
- To identify gaps in understanding genetic disorders and related services.
Main Methods:
- A survey was conducted among 707 school students (55.6% males, 44.4% females).
- Data collected via written responses to a close-ended questionnaire.
Main Results:
- Student knowledge of human genetics was found to be poor.
- Most students were unaware of the prevalence of genetic disorders.
- 75% of students recognized the need for genetic laboratory and counseling services.
- Over half of students could not identify a hospital with genetic laboratory services.
Conclusions:
- There is a significant need to integrate human genetics into the school curriculum.
- Awareness programs on genetic disorders and early detection are essential for intervention.

02:46Genetic Screens
Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which result in visible changes...

01:18Polygenic Traits
When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...
01:28Human Genetics
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

01:23Behavioral Genetics and Its Designs
Behavior genetics explores how genetic inheritance influences human behavior. It focuses on how genes, passed from parents to offspring, contribute to the development of behavioral traits and tendencies. This branch of genetics seeks to understand the complex interplay between inherited genetic factors and environmental influences in shaping our behaviors.
The primary methodologies used in behavior genetics include family studies, twin studies, and adoption studies, each providing unique...

01:25What is Population Genetics?
A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.While some alleles of a given gene might be observed commonly, other variants...
01:27Principles of Pharmacogenetics: Types of Genetic Variants
The human genome is over 99.9% identical between individuals, yet genetic differences exist at millions of bases. The human genome contains approximately 3 million variant positions per individual, many of which are heterozygous, contributing to genetic diversity and individual traits. Genetic variations include single-nucleotide polymorphisms (SNPs), insertions, deletions, and copy number variations (CNVs).SNPs, the most common variation, involve single-base changes in DNA. These can be...
