Therefore, breeding effects on physiology (e.g. water use efficiency) should be evaluated in order to quantify the global differences among commercial seed lots or clones compared with unimproved material.
Molecular breeding effects the permutation of diversity within a pool of related sequences and has proven to be an extraordinarily effective method to evolve proteins and pathways for better function.
This was used to control for amount of sexual experience across sires and to prevent breeding effects related to unfamiliarity with female mice.
Studies examining the long-term captive breeding effects on coho populations in Washington and Oregon have found that the genotypes of many wild populations have transformed to more closely resemble the genotypes of hatchery-reared fish [36].
The variable range of breeding effects from a base genome is an obvious illustration of this point.
It is worth mentioning that the QTL cluster on Chr.16 (marker locus CM0066a) had the largest favorable breeding effects on these four traits (SFC, STR, UHM, UI).
On the contrary, the QTL cluster on Chr.07 (marker locus C2-0114a) had the largest unfavorable breeding effects on SFC, STR, UHM and UI.
To detect differences in the 'production of male and female gametangia' and 'fertilized female gametangia', the analyses were performed considering the between-subjects effect (site and breeding system effect), the within-subjects effect (time effect) and interactions.
A GWAS was conducted using a mixed model including a regression on SNP genotype (0, 1 or 2 copies of the second allele), fixed effects of breed and gender, and a random polygenic breeding value effect to account for population structure.
In our case studies we considered models with additive genetic effects (breeding values u ), individual effects (environmental effects ε ), and several fixed effects.
Furthermore, as discussed by Hard (1995) and Waples (1999), the power of even the most ambitious monitoring programs to statistically detect a captive-breeding effect on phenotypic and life history traits is likely very low because natural variability in the same traits is very high.
