Based on a seasonally breeding model and the logistic model, the effect of impulse lethal control and impulse contraception control on rodent population dynamics is investigated.
(1998) used between 104 and 144 individuals per family, and the families were based on a backcross breeding design.
In index-based breeding, based on breeding values, the specific combination of dogs used for breeding will be more important than the status of the dog itself.
A conceptual design for a DEMO fusion reactor based on a dual coolant He/Pb15.7Li breeding blanket (DCLL) is being developed within the Spanish Breeding Blanket Technology Programme: TECNO_FUS.
Tree breeders typically make breeding decisions based on an individual's breeding value, which is the average performance of an individual's offspring.
Although there is increasing interest in implementing mate choice and it has been discussed for various zoo-based breeding programs (e.g., Grahn et al. 1998; Bryant 2005; Swaisgood and Schulte 2010; Asa et al. 2011), thus far, there have been no published experimental studies that compare breeding based on pedigree and breeding based on mate choice in a zoo setting.
The New Zealand Dryland Forests Initiative (NZDFI) has been working since 2008 to establish a eucalypt forest industry producing naturally durable timber based on a large scale-breeding programme of three species E. bosistoana F.Muell., E. quadrangulata H. Deane & Maiden and E. globoidea (Millen 2009).
The barley lines used to assess TSP marker amplification and for SNP genotyping were based on a collection of released varieties, breeding materials and mapping populations obtained from the University of Adelaide barley breeding program and included doubled haploid, F1 and F3 progeny.
A genetic trend analysis based on BLUP breeding values estimated across generations after the termination of the project suggested an accumulated response of 67%.
Based on a real dairy cattle dataset, breeding values were generated in the last generation of sires to mimic genomic pre-selection.
