Secondly, statistical methods need to be developed to incorporate whole methylome information jointly with environment and massive DNA sequence information. It will take only 2 minutes to fill in. It will take only 2 minutes to fill in. However, mate selection in order to obtain genotypes that favor a certain epigenotype could be implemented. The use of epigenetic phenomena for the improvement of sheep and cattle. Epigenetic includes any modification on the expression of genes that is due to factors other than a mutation in the DNA.

However, a low-cost procedure for epigenome screening would be necessary to implement these sorts of strategies. In light of the state of the art, it is doubtful that a large amount of heritable epigenetic variance exists in livestock populations. Nonetheless, the epigenomic era brings exciting discoveries and challenges that can potentially be included in livestock breeding programs.

Firstly, there is a need for a relatively inexpensive technology to sequence the epigenome on a large scale, as a large number of individuals are necessary to accurately estimate small epigenetic effects, and to estimate epigenetic variance at a population level. Secondly, statistical methods need to be developed to incorporate whole methylome information jointly with environment and massive DNA sequence information.

Lastly, practical implementation must be carefully evaluated to successfully incorporate epigenetic information in livestock breeding. For instance, mating strategies to increase certain epigenotype frequencies are valid only if epigenetic marks are heritable.

However, mate selection in order to obtain genotypes that favor a certain epigenotype could be implemented.

Abstract This article reviews the concept of Lamarckian inheritance and the use of the term epigenetics in the field of animal genetics. The old Ideas Jean—Baptiste de Lamarck — first proposed a clearly evolutionary theory in his Philosophie Zoologique.

Transgenerational Epigenetic Inheritance There exists some controversy on the existence of a heritable component of epigenetics. Potential Uses of Epigenetics in Animal Breeding Epigenetics is a recent research field, and to the best of our knowledge, is not yet used in selection or management strategies in livestock. Incorporating Epigenetic Information in Genomic Evaluations The epigenotype of an individual controls the expression of the genotype.

Cross-breeding and Epigenetic Breeding Programs If the epigenetic variance, or that due to imprinted genes, was sufficiently large, selection on male and female lines could be done separately Goddard and Whitelaw, Final Remarks In light of the state of the art, it is doubtful that a large amount of heritable epigenetic variance exists in livestock populations.
