Big Changes in Breeding and Genetics Thanks to Technology

Technology has changed the way we think about breeding plants and animals. This is especially true in the field of quantitative genetics, which studies how traits are passed down through generations. New tools and methods are making it easier to gather data, analyze it, and understand the genetics behind different traits.

1. Better Ways to Collect Data

In the past, collecting data about how plants and animals grow was hard work and could be biased. But now, we have modern tools like drones and sensors that help scientists gather a lot of information quickly.

For example, farmers can use drones to keep an eye on their crops without needing to do all the hard work themselves. With more data being collected, we can make better guesses about which plants or animals to breed.

Advanced ways of analyzing this data also help scientists understand how traits are inherited. For example, machine learning can find patterns in large amounts of data that might be missed otherwise.

2. Genomic Selection

Genomic selection is a major breakthrough in estimating breeding values, which help us understand the potential of individual plants or animals. With this method, breeders can use specific markers in the genome (the complete set of genes) to make more accurate predictions. These are often tiny changes in the DNA called SNPs.

This new way of selecting breeding candidates can speed up improvements. Breeders can choose the best plants or animals based on their genetics even before they are fully grown or tested.

3. Powerful Computers at Work

With the rise of big data and cloud computing, we can now analyze complex genetic information much faster. Special tools called genomic prediction models help process vast amounts of data.

These tools use advanced computing power to improve the way breeders select plants or animals. For example, software programs can help balance different traits, like crop yield and disease resistance, making sure both are considered in breeding.

4. Precision Breeding Techniques

Gene editing tools, like CRISPR-Cas9, allow scientists to make specific changes in an organism’s DNA. This means breeders can target important traits with great accuracy.

Instead of just mixing genes in the traditional way, gene editing can modify specific parts of DNA, helping scientists create new varieties of crops or livestock faster and with fewer risks. This helps avoid unwanted traits that might come up with traditional methods.

5. Combining Genomic and Phenotypic Data

Combining genetic data (genomic) with physical traits (phenotypic) helps breeders understand how traits are inherited. This combination provides a clearer picture of traits that involve many genes.

When scientists analyze both types of data together, they can better estimate how strongly traits are inherited. This helps predict how successful their breeding efforts will be.

6. Looking Ahead: Opportunities and Challenges

As technology keeps improving, future research will likely focus on building stronger models that also consider environmental factors. Making these tools available to farmers, especially in developing areas, could lead to better breeding practices worldwide.

But there are still challenges to think about. We have to consider the ethical issues around gene editing and how genetically modified organisms (GMOs) might affect our environment.

In short, new technology is changing how we calculate breeding values and select traits in genetics. The combination of better data collection, genomic selection, and powerful computing is making breeding programs more effective. This could lead to big improvements in agriculture for everyone. The key will be using these technologies responsibly and fairly.
