    Advantage of inbreeding. It increases homozygosity so is used for developing pure lines. Disadvantage of inbreeding. It causes inbreeding depression, due to that decline in survival and reproduction occur. Advantage of out breeding. It produces hybrids with desirable characters like better lactation period and high milk productions.   Laws governing the breeding of standard fowls; a book covering outbreeding [!] inbreeding and line breeding of all recognized breeds of domestic fowls, with chart, by Card, Wetherell Henry, Pages:

Waser --Theoretical and data pertinent to the relationship between heterozygosity and fitness / Jeffry B. Mitton --The evolution of inbreeding in haplodiploid . Since the mechanisms of inbreeding depression and outbreeding depression are different, you could have outbreeding benefits and disadvantages acting at the same time. What matters is the sum total of all the negative and positive factors. The book Science of Love and Betrayal by the eminent anthropologist Robin Dunbar discusses it in.

    Other articles where Outbreeding is discussed: inbreeding: common ancestry, as opposed to outbreeding, which is the mating of unrelated organisms. Inbreeding is useful in the retention of desirable characteristics or the elimination of undesirable ones, but it often results in decreased vigour, size, and fertility of the offspring because of the combined effect of harmful genes that. Kurt A. Rosentrater, A.D. Evers, in Kent's Technology of Cereals (Fifth Edition), Heterosis. Whereas continued inbreeding of outbreeding species leads to loss of vigour, F1 hybrids produced from inbred lines exhibit heterosis or hybrid vigour. This is the increase in size or vigour of a hybrid over the average of its parents, which is referred to as the mid-parent value.

The authors ask whether inbreeding is as problematic as biologists have thought, under what ecological conditions inbreeding occurs, and whether organisms that inbreed have mechanisms to dampen the anticipated problems of reduced genetic variation.5/5(1).

Philadelphia, Lippincott [©]. Out-breeding: Out-breeding is the breeding of the unrelated animals, which may be between individuals of the same breed but having no common ancestors for generations (out-breeding) or between different breeds (cross-breeding) or different species (inter-specific hybridisation).Out-crossing: This is the practice of mating of animals within the same breed, but having no common ancestors on.

Inbreeding has often been regarded as rare or pathological. This book, an edited volume of 18 chapters contributed by 26 authors, brings together a broad and deep review of the literature on inbreeding and outbreeding for a diversity of taxa, from both theoretical and empirical points of view.

In order to determine whether a particular mating is an outbreeding or inbreeding relative to your breed, you must determine the breed’s average inbreeding coefficient.

The average inbreeding coefficient of a breed will vary depending on the breed’s popularity or the age of its breeding population.

Other articles where Inbreeding and Outbreeding is discussed: Edward Murray East: In their book, Inbreeding and Outbreeding, East and Jones laid the basis for the concept of heterosis, or hybrid vigour (that hybrids are often more viable, stronger, and more fertile than inbred strains). East joined the faculty of Harvard University at the Bussey Institution facility in Jamaica Plain.

– inbreeding = in a population, a general pattern of regular and sustained mating between individuals who are related to one another as second cousins or closer. – outbreeding = in a population, a general pattern of regular and sustained mating in which individuals avoid second cousins or closer.

notice the “regular and sustained” bit.In biology, outbreeding depression is when crosses between two genetically distant groups or populations results in a reduction of fitness. The concept is in contrast to inbreeding depression, although the two effects can occur simultaneously.

Outbreeding depression is a risk that sometimes limits the potential for genetic rescue or augmentations. Therefore it is important to consider the.
