Document Summary
Agr 2350 midterm notes genomics and breeding strategies. Genome: composed of 4 nucleotides: adenine, thymine, guanine, cytosine. Examples: hiv: 9. 7k bases, chicken: 1b bases, cow: 2t bases, e. coli: 4. 6 m bases, mouse: 2. 5 b bases, vern: 3 b bases. Snp: single nucleotide polymorphisms: the difference between genes of 2 animals. Mice give no milk when this enzyme out. Lysine alanine exchange: +136 kg milk, +2. 27 kg protein, +0. 17% fat. 5. 19 kg fat: fatty acid profile altered. Hair sample (50-100 clean hairs) or nasal swipe. High through-put: 3000-777 000 snp in 1 go. Trainings group = older sires genotypes + bv based on offspring. Result of effect estimation: direct genomic breeding values. Arve x rolling view denver-et: progeny: Genomic breeding values are calculated from the dna of an animal. Breeding values are based on complex algorithms, which connect the genomic information (genotype) and the observed performance (phenotype)
