Tobiano spotting pattern in horses: linkage of To with AIa and linkage disequilibrium
Article Abstract:
The inheritance of the tobiano color pattern gene was studied in pedigrees using the polymorphic albumin gene in a sample of 2,786 tobiano and non-tobiano horses involved in paint horse breeding programs in the US. Findings revealed that the AIa and AIb alleles at the albumin locus was in coupling with To, the dominant tobiano allele. The frequency of the To:AIa linkage phase among all homozygous tobiano horses was 0.08. The To:AIb linkage phase was the most frequent. D = 0.056 at 79% of maximum linkage disequilibrium was the linkage disequilibrium parameter.

Linkage of semidwarf phenotype to interchange homozygosity in pearl millet
Article Abstract:
The semidwarf mutant homologous for chromosomal interchange in pearl millet is regulated by duplicate genes. One of the genes is near the interchange breakpoint. The difference in the gene pair placed far from the interchange breakpoint produces differences in the segregation patterns in sib and nonsib crosses. The parents in the sib crosses are homozygous recessive, while the nonsib parent is homologous dominant.

Inheritance studies of blue and golden varieties of tench
Article Abstract:
A study was conducted to investigate the inheritance of blue and golden colors in Tinca tinca L. by mating mutations to the normal or wild-type green phenotype and/or together. Findings showed that the crossing of heterozygous carries supported wild, blue and golden variants in tench. Results also indicated that color variants were mutations of two different, non-linked genes recessive to wild pigmentation.
