Assortative pairing by telomere length in king penguins and relationships with breeding success
International audience Telomeres are non-coding genetic repeats protecting the ends of linear chromosomes. Long telomeres are often associated with high individual survival, and inter-individual variation in telomere length has recently been proposed as a proxy for individual quality. Therefore, one...
