Well, there is a bit of misinformation here about chromosomes and "changing blood". Chromosomes are found in ALL cells of the body. They are not floating freely in blood. There are not a certain number of chromosomes per blood cells. Chromosomes are the basic building blocks of life, and are present in every single cell in the human body.

Blood does not create chromosomes. Chromosomes create blood cells. Chromosomes create muscle cells, skin cells, neurons, iris cells, skin cells etc - chromosomes create everything! When that one sperm cell delivers its package of one set of 23 chromosomes to the ovum that's it - that particular combination of 23 sets of chromosomes are going to be the only combinations of chromosomes you have for life. It isn't possible for blood to suddenly create different chromosomes mid-life and for a person to suddenly "become" a hermaphrodite. It just can't happen. Your set of chromosomes is determined and unchangeable at the moment of conception.

Unless there is a chromosomal abnormality, all cells in a female contain 23 pairs of X chromosomes except for the ovum, which contains 1 unpaired set of 23 x chromosomes. All cells in a human male contains 23 pairs of chromosomes also, except 22 are pairs of x chromosomes and the 23rd is a pair of xy. (And in the male spermatozoa contain 22 unpaired x chromosomes and the 23rd is either an x or a y.) Any medical professional or person familiar with chromosomal disorders would know this. Chromosomes don't float around freely in the blood. They are the building blocks, the coded information essential for cell life.

We have some male alters but I do not have much (or any) coconsciousness with them. Overall our person is female, but not very "girly". I think it would be really interesting for someone to research the body-mind connection in opposite gendered alters.
