Document Summary

Sex and gender y gender-specific behaviours result from complex interactions among self-assessment, societal expectations, genetics and hormones. These behaviours are related to gender identity our perception of our own gender y. The genetics of sex y y males have an x chromosome from the mother and y chromosome from the father. Females have two x chromosomes, one from each parent y y y: gender is determined by the x or y contribution from the father. The x chromosome is significantly larger than the y chromosome: the x chromosome contains about 1500 genes whereas the y chromosome contains less than 50. If a female has a defective x gene, there may be no negative consequence if her other x gene is normal. However, any defect in the single x chromosome of the male can lead to developmental defects: these are called x-linked diseases. The smaller y chromosome has fewer genes and less diverse functions.
