Genetics focuses on examining the structure and function of individual genes, whereas genomics delves into the collective interactions and functions of all genes, aiming to understand their combined impact on the organism’s growth and development.
‘Genetic testing’, ‘genomes’, ‘genotyping’ – these terms can be a perplexing jumble of scientific jargon, leaving many of us feeling overwhelmed and uncertain about where to start. But fear not!
In this FAQ post, we aim to be your accessible resource, demystifying the complex world of genomics and genetics in a way that speaks to you. Whether you’re looking to understand the genetic potential of your livestock, seeking insights to improve breeding outcomes, or simply curious about the wonders hidden within the genes of your sheep and cattle, we’ve got you covered.
Frequently asked questions
What are genes?
Genes are like the instruction manuals of all organisms. They are specific sequences of DNA that contain the directions to make proteins, which are the building blocks of life. These proteins have various roles – they can be enzymes that speed up chemical reactions, structural components that give cells their shape, or messengers that carry signals between cells. Each gene has a unique set of instructions, and together, all of an organism’s genes shape who or what they are.
What are genetics?
Genetics is the study of single genes and heredity, exploring how traits are passed from one generation to the next. It’s a fundamental branch of biology that helps us understand the underlying mechanisms that shape the characteristics of living organisms. In the context of livestock, genetics plays a crucial role in determining various desirable and detrimental traits, such as the presence or absence of horns, coat colour, wool quality, or whether an animal is predisposed to any genetic or inherited disorders.
What is a genome?
A genome is the complete set of an organism’s DNA, including all of its genes and non-coding regions (a part of an organism’s DNA that does not contain instructions for making proteins). It serves as a comprehensive blueprint that defines the genetic makeup and potential of an individual or species. Studying genomes is essential because it provides valuable insights into the genetic basis of various traits and characteristics.
Genomics varies from genetics, as it takes a more comprehensive approach, involving the analysis of the entire set of genes, as well as non-coding regions and other regulatory elements within an organism’s genome. It aims to understand the interplay between an organism’s genes and how they collectively contribute to their characteristics and functions, while also helping to study the interplay between genetic and environmental factors in shaping these characteristics.
What can the results of livestock genomic testing be used for?
Genotyping is the process of determining the DNA sequence, called a genotype, within the genome of an individual. It involves examining specific regions of the genome to determine an individual’s unique genetic profile. The regions investigated are typically single nucleotide polymorphisms (SNPs), which are the most common type of genetic variation.
XytoVet utilises custom-designed ThermoFisher Scientific microarray laboratory technology to perform genotyping on cattle and sheep samples. These microarray chips can genotype over 50,000 SNPs within the animals’ genomes, providing an abundance of highly informative data that can be utilised in a variety of ways, such as informing breeding plans for livestock by confirming pedigree and identifying animals with desirable genetic traits, such as increased milk production, improved meat quality, or disease resistance.
By selectively breeding animals with desirable traits, farmers can enhance the overall performance and productivity of their livestock, leading to healthier, more efficient, and economically valuable herds or flocks.
