Studies of heritability in thoroughbred populations are confounded somewhat by the presence of assortative mating. Although assortative mating itself will not make great changes to the magnitude of the assessment of heritability, it can exert a signi

Summary Interest in molecular biology and cloning of animals is high. It is widely predicted that biotechnological improvements will revolutionize animal production on farms. The environment, as a constraint, is usually ignored. Yet, as organisms nee

Summary It is known that performance in Thoroughbred racing is not a single character. This study analysed horses' performances for a number of parameters which may prove useful to Thoroughbred breeders. Each horse, and subsequently each sire and dam

Summary In the development of applied quantitative genetics to date it was assumed that natural selection was absent. Hence, an important part of the environment has been ignored and breeders have concentrated on estimated breeding values. The same i

Summary An analysis is described using heritability estimates for racing performance in the Australian Thoroughbred, calculated using the complete race results of two recent years. A number of methods, some new, for assessing racing performance were

Summary In general, the environment limits the fitness of individual animals, and environmental limitation leads to selection for “optimal”, intermediate values for all traits that matter, whether imposed by natural or artificial selection. We co

ummary We have provided a bridge between geneticists, who tend to concentrate on genes and their frequencies, and other biologists, who are much more aware of how severely the environment constrains and limits life. This bridge is the recognition tha

The occurrence of osteochondrosis in a breeding colony of labrador retrievers during an 11-year period was investigated. Management practices and environmental factors were similar for all dogs. In 1247 progeny, elbow lameness was recorded in 259 dog

A fatal syndrome of certain Arabian foals which begins at about 25 days of age (range 14 to 46 days) and which runs a course of about 23 days (range 13 to 42 days) is described. The syndrome, which affected 17 foals on a single farm is further charac
