X-X and X-Y Chromosomes interconnections and pheromone modification

A pheromone (from Greek φέρω phero "to bear" and hormone, from Greek ὁρμή "impetus") is a secreted or excreted chemical factor that triggers a social response in members of the same species. Pheromones are chemicals capable of acting outside the body of the secreting individual to impact the behavior of the receiving individual.[1] There are alarm pheromones, food trail pheromones, sex pheromones, and many others that affect behavior or physiology. Pheromones are used from basic unicellular prokaryotes to complex multicellular eukaryotes.[2] Their use among insects has been particularly well documented. In addition, some vertebrates and plants communicate by using pheromones.
