A research study was carried out on the indirect selection efforts amongst small scale holders of West African Dwarf (WAD) goats based on coat pigmentation and wattle types in Ogbomoso, Nigeria using personal interviews and structured questionnaires given using simple random on-farm techniques. The questionnaires were focused on the ownership distribution, preferred pigmentation and wattle type...

In soybean seeds, numerous variations in colors and pigmentation patterns exist, most of which are observed in the seed coat. Patterns of seed coat pigmentation are determined by four alleles (I, i(i), i(k) and i) of the classically defined I locus, which controls the spatial distribution of anthocyanins and proanthocyanidins in the seed coat. Most commercial soybean cultivars produce yellow se...

This study was conducted to establish genetic criteria for phenotypic characteristics of Hanwoo cattle based on allele frequencies and genetic variance analysis using microsatellite markers. Analysis of the genetic diversity among 399 Hanwoo cattle classified according to nose pigmentation and coat color was carried out using 22 microsatellite markers. The results revealed that the INRA035 locu...

Most commercial Glycine max (soybean) varieties have yellow seeds because of loss of pigmentation in the seed coat. It has been suggested that inhibition of seed coat pigmentation in yellow G. max may be controlled by homology-dependent silencing of chalcone synthase (CHS) genes. Our analysis of CHS mRNA and short-interfering RNAs provide clear evidence that the inhibition of seed coat pigmenta...

BACKGROUND Congenital sensorineural deafness (CSD) is the most common type of deafness in dogs and it occurs in numerous canine breeds including the English bull terrier. This study estimates prevalence, heritability and genetic correlations of CSD and coat pigmentation phenotypes in the English bull terrier in England. RESULTS Hearing status was assessed by brainstem auditory evoked response...

Chimaeras, made by aggregating two embryos from the randomly-bred Q-strain, and X-inactivation mosaics both have similar, balanced distributions of pigmentation in the dorsal coat, while (C57BL X C3H) F1 reversible Recessive chimaeras tend to have an unbalanced pigment distribution, with a higher proportion of F1 pigmentation in the posterior than in the anterior part of the coat. This observat...

THE COAT COLORS OF MICE. A MODEL FOR MAMMALIAN GENE ACTION AND INTERACTION. By Willys K. Silvers. New York, Springer-Verlag, 1979. 379 pp. $29.80. This detailed monograph on pigmentation in mice is of value in drawing together the data and conclusions of a large number of studies over a period of many years. Apart from their intrinsic beauty, the coat colors of mice have played an important rol...

Yellow seed colour in Brassica napus is a desired trait and has a strong impact on the quality of Canola and the processed products from the seed. The trait is accompanied with a thinner seed coat when compared to black seeds. For the model plant Arabidopsis thaliana, different mutants have been characterised showing the transparent testa phenotype to be associated with light seed colour due to...
