17. Marker-assisted selection uses genomic markers to identify desirable traits in plants and animals, speeding up the breeding process.
18. Genomic studies have identified genes responsible for drought tolerance in crops, helping develop varieties that can withstand harsh conditions.
19. Livestock genomics helps in selecting animals with superior traits, improving meat, milk, and egg production.
20. Genomic research in aquaculture aims to enhance the growth, disease resistance, and quality of farmed fish and shellfish.

Ethical and Social Implications

The rapid advancements in genomics raise important ethical and social questions. Here are some considerations.

21. Genetic privacy is a major concern, as genomic data can reveal sensitive information about an individual's health and ancestry.
22. There are debates about the ethical implications of gene editing technologies like CRISPR, especially regarding their use in humans.
23. Genomic research must address issues of consent, ensuring that individuals understand how their genetic data will be used.
24. There is a risk of genetic discrimination, where individuals could be treated unfairly based on their genetic information.
25. Public awareness and education about genomics are crucial to ensure informed decision-making and ethical use of genomic technologies.
