show there is clear a difference between the brains of homosexuals and heterosexuals‚ and part of it lies within the hypothalamus. The hypothalamus is a small part of the brain that controls sexual behavior‚ among other things‚ and it responds to pheromones (Hypothalamus‚ n.d.). Several nuclei in the hypothalamus are sexually dimorphic; this includes the interstitial nucleus of the anterior hypothalamus (INAH). The INAH is a nucleus located between the groups of tissue in the anterior hypothalamus

research studies the effects of UV radiation on sex-determination in Ceratopteris richardii. Sex determination in Ceratopteris richardii is determined by antheridiogen‚ a pheromone that promotes maleness. In this experiment‚ UV radiation was used on the wild type and mutants Her1‚ which are insensitive to the male-inducing pheromone (does not form male gametophytes). Ceratopteris richardii spores were exposed to UV radiation at different stages during their life cycle. Wild type gametophytes treated

attract insects. Each Ophrys species has its own insect that it depends on for pollination. Bumblebee Orchids are completely dependent upon bumblebees (Eucera algira). Each flower has a lip that tricks the insect visually and by mimicking female pheromones that attract the males. The Bumblebee Orchid has 2 to 3 flowers that look and smell so much like female bumble bees‚ that the chemical signals stimulate the bees sexually. The smell‚ look‚ and feel of the lip of the flowers mimic female bumblebees
