Introduction to Ecology; Correlation between hair color and gender/sex

Methods: To assess the relationship between hair color and gender, 22 human subjects were surveyed. For hair color options given, there was only red, brown, blonde and black. For gender options given, there was only male and female. Subjects picked which options best identified themselves. Study Site: Indoors at the Lumbers building at York University in a laboratory classroom;GPS 43.774732, -79.504990. There were no problems with visibility since weather was clear and lighting in the room was bright. No one's hair was covered and hair was clearly visible. All data was verbally communicated from the participants. Hypothesis: More females than males will display light hair colors (brown, red, blonde) due to the sexual selection by males that may favor light hair colors over darker hair colors. <br>Predictions: 1)The ratio of females with light hair color will be higher than the ratio of males with light hair color because of sexual selection in light hair color(brown, red, blonde) in females. 2) Females will have a larger occurrence of hair colors different from natural biological hair color because of popular personalities or personal preference.

研究方法：为评估发色与性别的关联，本研究招募22名人类受试者开展调研。本次调研提供的发色选项仅限红色、棕色、金色与黑色，性别选项仅限男性与女性，受试者需选择最贴合自身身份的选项。
研究场地：本次实验于约克大学（York University）兰伯斯大楼（Lumbers building）内的实验室教室开展，地理坐标为GPS 43.774732, -79.504990。当日天气晴朗，室内照明充足，无视野遮挡问题；所有受试者的头发均未被遮挡，发色清晰可辨。所有数据均由受试者口头告知采集。
研究假设：基于雄性更偏好浅发色（棕色、红色、金色）而非深发色的性选择倾向，女性中拥有浅发色的比例将高于男性。
研究预测：1. 由于雌性存在浅发色（棕色、红色、金色）的性选择倾向，拥有浅发色的女性比例将高于拥有浅发色的男性比例。2. 受流行审美倾向或个人偏好影响，女性出现与天然生物发色不同的发色的概率将更高。
