A ''Zhen'' has a vagina which is only useable for pleasure, not reproduction. They also have 4 teats on their lower abdomen and the ability to produce a pouch that is used to house the transferred embryo while it grows. | A ''Zhen'' has a vagina which is only useable for pleasure, not reproduction.

The gender determining [http://en.wikipedia.org/wiki/Chromosome chromosomes] are called S, C, and T (rougly analogus to the Terran X and Y). Each Andorian has three of these chromosomes and the combination determins gender. The individual is Shan if they have SSS, Chan if they have SSC, Thaan if they have SST, and Zhan if they have SCT. Each [http://en.wikipedia.org/wiki/Gamete gamete] contain only one of the three. Shan eggs always have a S chromosome. Thaan and Chan sperm have a 50% chance of containing a S, or either a T or C respectively. The reason its not 33% chance of an S is because during early development, the second S chromosome in the Thaan and Chan undergoes and chemical change that isolates it from the other chromosomes and is expessed from the cells during [http://en.wikipedia.org/wiki/Meiosis meiosis]. Although punnant squares are usually used to show the genotype probabliliy of offspring, it works on the same prinipal for chromosomes as far a gender is related. | |||

With the S given by the Shan ommited because it is present in all genders. His produces an exact 1/4 chance of a child being every gender. The Zhan does not contribute any genetic material. This is because by the time the embryo is transfered to the Zhan, it is to deveolped to accept new genetic material into all of its cells. | |||

Once the baby has emerged from the pouch the ''Zhen'' will come out of protective seclusion. Her pouch will dry up and flake away. The other 3 bondmates will then assist by rubbing her with oils and help to peel off the remains of the now useless pouch. | Once the baby has emerged from the pouch the ''Zhen'' will come out of protective seclusion.

Due to the fact that Andorian fertility periods have been slowly getting shorter they will try to conceive as many children as possible during this period and since fewer viable children have been born the Andorians have been forced to arrange bondings among genetically compatible members of their society. This has replaced allowing the young people to pick their bondmates. As with most humanoid races most Andorians will experiment with sex at puberty. Since their fertility period is so short it is impossible to produce offspring before or after this time. If they are found to be genetically acceptable they will generally be bonded by the age of 23. | Due to the fact that Andorian fertility periods have been slowly getting shorter they will try to conceive as many children as possible during this period and since fewer viable children have been born the Andorians have been forced to arrange bondings among genetically compatible members of their society.
