This can occur when multiple zygotes (such as fraternal twins) combine and develop into one fetus. Sex-chromosome discordant chimerism occurs when at least one embryo with XX chromosomes fuses with at least one embryo with XY chromosomes. A person who develops this way would have sets of both XX and XY chromosomes, or a chromosome pattern of 46XX/46XY, and could have a wide variety of different possible sex characteristics. Many people with chimerism and XX/XY chromosomes have both ovarian and testicular tissue, while others have only testes or only ovaries, and still others have gonadal dysgenesis. Some have noticeable genital differences and others do not.
