Genetic improvement (animal breeding) is based on the principle that the products (milk, meat, wool, etc.) and services (e.g. transport, draught power or cultural services) provided by animals are a function of their genes and the environmental influences that they are exposed to. Improvement can be achieved by selecting genetically superior animals to be the parents of the next generation.

Earth contains millions of different species that all look different from one another. While some species look more similar to each other than others, like lions and tigers, they will still have differences between them. Even within each species, individuals look similar to each other but they are not identical. These differences and similarities a...
Changes to an individual’s DNA are called mutationsA change in an organism’s DNA. This can be a change of a single letter or a much bigger change of hundreds of letters at once. (Figure 2). Mutations can arise when mistakes are made while cells are copying DNA, like making a spelling mistake when copying a word. These mutations make up a species’ g...
When a species has a lot of differences in its DNA, we say that genetic diversity is high . In species with high genetic diversity, there are lots of mutations in the DNA, which cause differences in the way individuals look as well as differences in important traits that we cannot see . This is called adaptationThe process of a species changing in ...
When few mutations are found in the DNA of a species, genetic diversity is said to be low . Low genetic diversity means that there is a limited variety of alleles for genes within that species and so there are not many differences between individuals. This can mean that there are fewer opportunities to adapt to environmental changes. Low genetic di...
We hear a lot about the loss of species in the world, but we are also seeing a loss of genetic diversity within species. The increasing number of people on Earth and our increasing use of natural resources has reduced space and resources for wild species. Over time, many wild animal and plant populations have become smaller or more isolated. Many s...
We must preserve and protect genetic diversity. This can be done through the conservation of our remaining wild populations . We can use nature reserves and wildlife bridges to reconnect wild populations that have become separated by our cities and highways. We can also restore habitats, because this will allow wild populations to get bigger. Somet...
The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.
Mar 16, 2023 · In agriculture, genetics is the science of improving crops and livestock by manipulating their genetic makeup. As crops and livestock are the foundation of agriculture, genetics plays a vital role in ensuring the continued success of this important industry. By understanding and manipulating the genes of plants and animals, farmers can produce ...

Oct 19, 2023 · Early farmers crossbred animals and plants for desirable . traits. Over many generations, they domesticated dogs and other farm animals from wild animals.It wasn’t until the mid-1800s that people began to study the inheritance of traits as a science. A pioneer in these studies was Gregor Mendel, a monk living in what is now the Czech Republic.
