Comparing SNP Panels and Statistical Methods for Estimating Genomic Breed Composition of Individual Animals in Ten Cattle Breeds
He et al. BMC Genetics (2018) 19:56 https://doi.org/10.1186/s12863-018-0654-3 RESEARCH ARTICLE Open Access Comparing SNP panels and statistical methods for estimating genomic breed composition of individual animals in ten cattle breeds Jun He1,2†,YageGuo1,3†, Jiaqi Xu1,4, Hao Li1,5,AnnaFuller1, Richard G. Tait Jr1,Xiao-LinWu1,5* and Stewart Bauck1 Abstract Background: SNPs are informative to estimate genomic breed composition (GBC) of individual animals, but selected SNPs for this purpose were not made available in the commercial bovine SNP chips prior to the present study. The primary objective of the present study was to select five common SNP panels for estimating GBC of individual animals initially involving 10 cattle breeds (two dairy breeds and eight beef breeds). The performance of the five common SNP panels was evaluated based on admixture model and linear regression model, respectively. Finally, the downstream implication of GBC on genomic prediction accuracies was investigated and discussed in a Santa Gertrudis cattle population. Results: There were 15,708 common SNPs across five currently-available commercial bovine SNP chips. From this set, four subsets (1,000, 3,000, 5,000, and 10,000 SNPs) were selected by maximizing average Euclidean distance (AED) of SNP allelic frequencies among the ten cattle breeds. For 198 animals presented as Akaushi, estimated GBC of the Akaushi breed (GBCA) based on the admixture model agreed very well among the five SNP panels, identifying 166 animals with GBCA = 1. Using the same SNP panels, the linear regression approach reported fewer animals with GBCA = 1. -

II. Outbreeding and Hybrid Vigour
II. Outbreeding and Hybrid vigour II. Outbreeding and Hybrid vigour • Outbreeding is the opposite of inbreeding, it is the mating of animals less closely related than the average relationship within the breed. • If two individuals do not have any ancestors in common for five or six generations back in their respective pedigrees, they are usually thought not being any more related than the average of the population Consequences of outbreeding 1. Outbreeding increases the number of pairs of heterozygous genes in the individual 2. Outbreeding tends to decrease breeding purity 3. Outbreeding tends to cover up detrimental recessive genes. 4. Phenotypically, outbreeding usually improves traits related to physical fitness (hybrid vigour). Hybrid vigour or heterosis • Heterosis, or hybrid vigour, is the name given to the increased vigour of the offspring over that of the parents when unrelated individuals are mated. • In 1914 Professor Shull proposed for the first time the word “heterosis ” • The best known example for hybrid vigour in animals is the mule (male ass and mare) • The reciprocal cross, called the hinney or jennet Types of heterosis • There are three main types of heterosis (Individual, Maternal, Paternal) 1) Individual (direct) heterosis • It is the improvement in the performance of crossbred individual above the average of its parents. • It is affected by Individual’s gene that directly affects on its performance. • All traits have what is called a direct or individual component of heterosis • Examples (weaning weight, yearling weight and carcass traits) 2- Maternal Heterosis • It is the improvement in the performance of the crossbred mother over the average of purebred mothers Example: I. -

The region’s environment generally can be characterized as subtropical, i.e. hot, humid summers with ample rainfall supporting good forage production. Efficient cow-calf production in the humid South is dependent on heat and parasite tolerance and good forage utilization ability. Brahman and Brahman-derivative breeds generally possess these characteristics and excel in maternal traits. Consequently, they have been used extensively throughout the Southern Region in crossbreeding systems with Bos taurus breeds in order to exploit both breed complementarity and heterosis effects. However, several characteristics of Brahman and Brahman crossbred cattle, such as poor feedlot performance, lower carcass quality including meat tenderness, and poor temperament, whether real or perceived can result in economic discounts of these cattle. Therefore, determining genetic variation for economically important traits among Brahman and Brahman-derivative breeds and identifying tropically adapted breeds of cattle from other countries that may excel in their performance of economically important traits in Southern U.S. -
