The four applications of genetics to human problems include;
- Medicine
- Forensics
- Agriculture
- Scientific research
Explanation:
Genetics is a branch of science that is focused on the study of genes, how they vary across individuals and species, and how they are inherited.
Genetics has allowed humans to improve on their health. By understanding how genes work, genes therapy has been used to correct malfunctioning genes in patients.
In forensics, laboratory techniques like gel electrophoresis are used to compared genes (SNPs) of suspects with those from the crime scene to convict criminals.
In agriculture genes for tolerance to diseases and droughts have been incorporated in food crops to help improve yield even in harsh environs.
Genetics has contributed to scientific research because it has allowed humans to map their genome and enabled them to understand how genes are expressed and how this shows in their phenotype.
