102500 The chromosome construction of males and females are different. According to biological analysis XX-type chromosomes are found in females and XY-type of chromosomes are found in males. However, there are various effects of society, ethnicity and culture that complete the behaviour and identity of men and women based on the difference in the gender group (Zevin, 2014, p.57). The impact of ethnicity and culture over sex and gender can be clearly illustrated with the help of the research of Margaret Mead. Margaret explained about different cultures with wide variety of examples. According to Margaret’s research it has been observed that the native people of New Guinea have completely different approach towards the two major genders that represent the human society. For example, the people of Tchambuli culture in New Guinea have represented women to be the leading members in their society (Wetherell, 2001, p.88). Females have the ultimate control of economic life and they work towards the betterment of people. According to the research it has been observed that the women participate in different type of professions to earn their living. The males of the society generally participate in arts and theatres. The males of the society do-not have any direct control over the regulation of economy of the Tchambuli society. The Tchambuli women have been found to be engaging themselves in manufacturing of products and food. The initiations of sexual relations are also taken by the females of the society.
