As a first essay we propose a discussion about a difficult and somehow trouble some question in applied animal genetics how to take proper account of the observed data being selected data Several attempts have been carried out in the past 15 years without any clear and unanimous solution. In the following Im Fernando and Gianola propose a general approach that should make it possible to deal with every problem. In addition to the interest of an original article we hope that their own discussion and response to the comments given by Henderson and Thompson will provide the reader with a sound insight into this complex topic. This paper is dedicated to the memory of Professor Henderson who gave US here one of his latest contributions. The Editorial Board Summary - Data available in animal breeding are often subject to selection. Such data can be viewed as data with missing values. In this paper inferences based on likelihoods derived from statistical models for missing data are applied to production records subject to selection. Conditions for ignoring the selection process are discussed. animal genetics selected data missing data likelihood inference Resume Les methodes d inference fondees sur la vraisemblance en génétique animate prise en compte de données issues
