lost genes from a leaf genome or an intermediate core gene. Such
numbers are very interesting because they give an information about
the evolution: how many genes were lost between two species whether
-they belong to the same familie or not. By the principle of
+they belong to the same family or not. By the principle of
classification, a small number of genes lost among species indicates
that those species are close to each other and belong to same family,
while a large lost means that we have an evolutionary relationship
