A propagation loss of 3.6 dB/mm and flat dispersion over a large wavelength band is reported with an easy-to-implement design without disturbing the periodicity (keeping lattice constant and hole diameter fixed) in the line-defect photonic crystals.
Assuming neutral evolution, 1/ N x of the substitutions entering the germ line will become fixed in the maternal line of descent, so that the mutation rate can be estimated as (2.4) μ m = α / N x t ≈ β 2 N x t ln (θ − 1 − 1 ), where t is the generation time.
MAPfastR provides functionality for F2 crosses and backcrosses under the assumption that different QTL alleles are fixed in the founder lines (Crooks et al. 2011), line-cross analyses allowing for within-line segregation (flexible interclass analysis [FIA]; Rönnegård et al. 2008), and tests for epistatic interactions (Carlborg and Andersson 2002).
The favourable allele of the SNP with the largest effect within the window that explained the largest proportion of genetic variation was fixed in the Fayoumi line but was also segregating in the broiler line; thus, it was not possible to determine which line contributed the favourable allele.
At generation S0 of the selection experiment, genomes of all individuals were scanned to identify bi-allelic QTL affecting DR, where one of the alleles happened to be fixed in the recipient line, but an alternative allele existed in the donor line.
For many of the positions appearing as Simple SNPs in our data, it's likely that, in the process of homogenisation associated with inbreeding, opposing allelic variants were fixed in the inbred lines (eg. AT[O]AT[P'] homogenised to TT[O]TT[P'] in one inbred line and to AA[O]AA[P'] in another.
Analysis of allele markers frequencies in inter-gene populations showed segregation distortion with a higher than expected frequency of alleles from the Mesoamerican gene pool, many of which were fixed in the F7 lines.
The CNVRs fixed in the susceptible lines were significantly enriched in genes involved in MAPK signaling pathway.
Interval mapping was conducted using regression methods, in which alleles were assumed to be fixed in the founder lines.
The allele substitution effect is underestimated when the favourable QTL allele is not fixed in the donor line.
In contrast, the QTLExpress method assumed that alternative QTL alleles were fixed in the founder lines, and only one substitution effect was estimated over all families.
