Deleterious Recessive Genes in Dairy Bulls Selected at Random.
HE genetics of farm mammals have not been investigated in a manner T comparable to the intensive studies made, during the last forty years, with Drosophila, laboratory rodents, and chickens. Nevertheless, a large number of mutant genes have been reported in farm mammals. These mutants have been discovered more or less by chance when sufficient inbreeding has brought them to light. Many more hav...
متن کاملObstruction of adaptation in diploids by recessive, strongly deleterious alleles.
Recessive deleterious mutations are common, causing many genetic disorders in humans and producing inbreeding depression in the majority of sexually reproducing diploids. The abundance of recessive deleterious mutations in natural populations suggests they are likely to be present on a chromosome when a new adaptive mutation occurs, yet the dynamics of recessive deleterious hitchhikers and thei...
متن کاملInvestigation of Two Recessive Disorders in Breeder Bulls of Abbas Abad Animal Breeding Center
To prevent distribution of recessive alleles in dairy herds all bulls used for AI (Artificial Insemination) haveto be tested. In this study 26 blood and 4 semen samples were supplied from Iranian Holstein bulls used forAI. Genomic DNA was extracted from 100 μl of blood and 200 μl of semen. Samples were tested by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR...
متن کاملExtra virgin olive oil in maternal diet increases osteogenic genes expression, but high amounts have deleterious effects on bones in mice offspring at adolescence
Objective(s): Maternal high-fat diet has been shown to have deleterious effects on the offspring bones. However, there is no study to assess the effects of type and amount of maternal dietary oil in an isocaloric diet, with focus on extra virgin olive oil (EVOO). The objective of the current study was to test the hypothesis that type of maternal dietary oil has more effects than its amount in a...
متن کاملExamination of more frequent genetic evaluations for dairy bulls.
Genetic evaluations of Holstein bulls for February 1997 through May 1998 were examined to determine the value of more frequent evaluation for quicker identification of bulls with changing predicted transmitting abilities (PTA) and of new bulls of superior genetic merit. Changes in PTA between evaluations that were calculated quarterly rather than semiannually were reduced by 30%. About two-thir...
