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.

Genetics is the study of genes and their effects in living organisms. The information in an organism’s genes provides a biological blueprint for its appearance, function and survival and largely defines its similarities and differences with other organisms. The genetics of livestock are therefore a critical factor influencing animal ...

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.
Dec 20, 2023 · In conclusion, genetic diversity is incredibly important for wildlife species’ survival and the overall health of ecosystems. It allows for adaptation, increases resistance to diseases and environmental stressors, prevents inbreeding and its negative consequences, and maintains stability within ecosystems.
The process of selecting animals based on their genetics has helped advance agricultural productivity over the past 50 years. A good example of genetic improvement is in poultry breeding. Between 1957 and 2001, poultry breeders selected traits to increase the body weight of broiler (meat) chickens. Due in large part to genetic selection ...
May 15, 2019 · Characterizing, sequencing and preserving genetic diversity representing commercially important animals, their wild relatives, rare breeds developed for specific traits, and specialized research populations will enhance discovery science, provide a resource of genetic diversity that will enable breeding strategies to respond to changing priorities, and allow recovery from disease outbreaks or ...

Livestock populations, or animal genetic resources for food and agriculture (AnGR), provide crucial options for the sustainable development of livestock production. Diverse animal genetic resources provide the capacity to adapt and resilience in the face of climate change, emerging diseases, pressures on feed and water supplies and shifting market demands.
