Evidence for double reduction was observed at a number of loci, but no genotypes were observed that could only have originated from double reduction.
The cell residence time of a cellular-only MS originated at double coverage area, T c, d c a c a, can be evaluated as T c,dca ca = T 1 dca + T 1 coa + ⋅ ⋅ ⋅ + T N dca dca + T N coa coa, where Ndca and Ncoa are the number of entrances of the double coverage area and the cellular-only area until the MS moves out the cell, respectively.
The missing history of the heart is here Where the shape of Love originated - Double lobe of an ancient seedpod.
Considering that triticale is predominantly a self-pollinated species and some of the forms that originated from double haploids were developed via anther culture, the plant material used is appropriate for association mapping studies with dominant marker platforms [ 14, 55].
The presence of four 5S and fifteen 25S rDNA sites suggests that the decaploid cytotype for CFRA 110 of the F. virginiana subsp. platypetala originated from doubling of an interspecific hybrid between an octoploid and a diploid species, which are probably F. virginiana and an American subspecies of F. vesca, respectively, due to the North American geographic collection site of CFRA 110.
Specifically, recrystallized grains originating from double twins make the main contribution to texture modification, which contrasts to the opposite view that has been reported in the past decades.
Indeed, we demonstrated in this study that the presence of telomeric sequences occurred only in current telomeres, which confirms a previous hypothesis that Rb-fusions [ 32] originate from double chromosome breaks with the loss of telomeric sequences.
Similarly, the channel holding times of cellular-only calls originated in the double coverage area and in the cellular-only area are given by min(T v, T c,dca ca ) and min(T v, T c,coa ca ), respectively.
More recently, novel CCoV-II strains, which likely originated from a double recombination event with TGEV, occurring in the 5′ end of the spike protein gene, have been isolated (14, 15 ).
The small size of the S. clavuligerus chromosome and the absence of hallmarks typical for Streptomyces chromosomal termini, together with the remarkable presence of such terminal hallmarks on the plasmid, suggest that the megaplasmid may have originated by a double recombination of a smaller plasmid with the chromosome.
Furthermore, it is unlikely that the brittle rachis of this line originated from a double recombination event between btr1Btr2 and Btr1btr2 to generate a brittle Btr1Btr2 genotype, because these two loci are tightly linked (Takahashi and Hayashi, 1964; Komatsuda et al., 2004).
