>>645910 *another facepalm* Inbreding, *dramatic pause* results from excessive identical gene pairs. In a child of siblings, about 25% of pairs of genes are identical. In a child produced from sperm and egg with the same genotype, 50% of pairs of genes would be identical. It would not be a clone. The sperm has a 50% chance of passing on either gene in each pair. The egg has a 50% chance of passing on either gene in each pair, it would not automatically include the other gene.
To illustrate, an example. Suppose the father-mother had a single sickle cell gene. The child would not automatically be a malaria resistant sickle cell gene carrier. It would have a 50% chance of having malaria resistance, a 25% chance of having a double of the normal gene, hence no malaria resistance, and a 25% chance of having sickle cell anemia.
Furthermore, if the parent was genetically female, there would be a 50% chance of the child having a double copy of the same X chromosone, giving it the same chance of X chromosone linked disorders, such as color blindness, as a male despite being female. But, if the parent was genetically male, there would be a 50% chance of the child being male, a 25% chance of it being female and automatically having the same X chromosone based disorders that the parent had, and a 25% chance of it having 2 Y chromosones and no X, most likely resulting in very severe problems from that alone.
Of course, this doesn't neccessarily apply to this case anyway, since ranma might not have the same genotype as a male and female, as evident by the different hair colors. Red hair is caused by a weird recesive gene(which some even speculate came from neanderthals), and IIRC it also needs to have the genes for light hair on top of that.
