The Difference

The distribution of whole blood potassium concentration in 1783 Welsh Mountain sheep shows marked bimodality, varying about two modes, of 44 and 14 m-equiv./l.The difference between high (HK) and low (LK) potassium types was not clear-cut. About 5 % of animals lay in the area where the tails of the two distributions merge.Haematocrit values and plasma potassium concentrations were used to estimate erythrocyte potassium levels. They confirmed that the bimodality is due to variation within erythrocytes but did not offer a satisfactory method of allocating intermediate animals.

Root Meristems

A red anthocyanin pigment which occurs in the root meristems of certain PhalariB species has been identified as a glycoside of pelargonidin. The pigment has been observed only in plants of the three polyploid species P. minor, P. tuberosa, and P. arundinacea, and is absent in the diploid members of the genus. Genetic studies indicate that the character is simply inherited, involving a single major dominant gene controlling the production of the pigment, and a series of modifier genes influencing the level of its expression. In P. minor, a self.pollinating annual, the gene is widespread and homozygous, but in P. tuberosa and P. arundinacea, both cross-pollinating perennials, it occurs at low frequency largely as the hetero-zygote, and is restricted to certain areas within the range of the distribution of these species. The origin of the gene in Phalaris, and its possible adaptive significance is discussed. Also its value as a single gene marker in breeding studies is indicated.
