Medullary cystic kidney disease with hyperuricemia and gout in a large Cypriot family: no allelism with nephronophthisis type 1.
Allelism between bands is not known without complex segregation analysis, and the pattern is treated as a multicharacter phenotype.
Allelism of factors affecting quantitative variation in bristle number to candidate loci in Drosophila melanogaster.
The data are voluminous, and our opportunity to deal with them here quite limited, so we present a highly summarized snapshot of par allelism in Figure 1.
However, further studies of allelism tests and analyses of molecular markers are necessary to confirm whether the genes are allelic or at different loci.
d], were then crossed to normal durum (56-1) to create a segregating population (2) which can be used to determine allelism between the two genes.
Additionally, "alleles" can potentially be represented by large numbers of cosegrating bands and the degree of band allelism appears to vary among taxa and probes (Brock and White 1991).
However, with sufficient resolution, multiple allelism for dominant Ol genes should result in observation of simple genetic ratios in progenies of crosses between low-oleate parents.
Our preliminary data from molecular mapping and allelism tests suggested that resistance in SW8 was conferred by a gene different from H13 in Molly (PI 562619), H22 in KS86WGRC1 (PI 499691), H23 in KS89WGRC3 (PI 535766), and H24 in KS89WGRC6 (PI 535769).
Mistaken identity of the latter gene could also explain at least some of the inconsistencies surrounding earlier studies with Dn5, particularly tests of allelism with the other group 7 Dn loci.
A consequent problem is that because allelism cannot be established, it is not possible to ascertain whether individuals are homozygous or heterozygous.
