Record number: 1, Textual support number: 1 CONT

De-extinction reflects the process of generating an organism that both resembles and is genetically similar to an extinct species by resurrecting its lost lineage of core genes...  3, fiche 1, Anglais, - de%2Dextinction

There are at least three semi-successful techniques for de-extinction so far. 1) Selective back-breeding of existing descendents to recreate a primordial ancestor... 2) Cloning with cells from cryopreserved tissue of a recently extinct animal can generate viable eggs.... 3) Allele replacement for precisely hybridizing a living species into an extinct species...  4, fiche 1, Anglais, - de%2Dextinction

Given that many elite lines are derived from F3 to F5 selections of a cross, it is reasonable to assume that at least some genetic heterogeneity exists within lines. In such cases, the frequency of each allele within the line was assumed to be 0. 5 instead of either 1. 0 or 0 as for homogeneous lines. This adjusts the allele frequency data for the purposes of calculating the probability of inheriting an allele from an ancestor or for calculating the frequency of an allele within the elite population.  1, fiche 2, Anglais, - allele%20from%20an%20ancestor
