Genome dynamics in livestock breeding: How the features of the genome affect breeding
KEY POINTS- To make breeding more sustainable and precise, we need to understand how the features of the genome affects breeding.
- Accumulated sequence data and new methods make realistic models of genomes possible.
- This project will improve our understanding of how the features of the genome affect farm animal breeding.

Short summary
Background
Animal breeding makes use of the genetic variation between individuals of a population. Modern farm animal breeding makes use of genomic selection, using DNA tests of markers spread out over the genome to connect genetic variants to traits under selection, and make accurate selection decisions.
About this project
To make breeding more sustainable and precise, we need to understand how the features of the genome affects breeding. Accumulated sequence data and new methods make realistic models of genomes possible.
We need to know:
- How variable recombination and mutation affect genetic variation in livestock
- How evolutionary history and linkage constrain genetic variation in livestock
- How genome features affect our ability to detect and select genetic variants that affect traits
This project will analyse sequence from cattle, pigs and chickens to discover how genetic variation is distributed in the genome, in order to improve our understanding of how the features of the genome affect breeding.
Participants
In addition to the listed researchers at SLU, Elisenda Rius-Vilarrasa (Växa Sverige) also participates in the project.
