The breeders equation

WebApr 12, 2024 · Yield is one of the most important traits of arabica coffee. Plant breeders seek to maximize yield directly or indirectly, using other related traits. The standard multi-trait genome-wide association study (MTM-GWAS) does not accommodate the network structure of phenotypes, therefore, does not address how traits are interrelated. We … WebBiology questions and answers. 1. The breeder's equation, R = h2*S, tells us about which of the following: a)How many ways there are deviating from the mean value of a population from which we wish to breed variants possessing desirable traits. b)How to have more children within a given amount of time. c)The response to selection, quantified as ...
