Non-canon Andorian

This page contains non-cannon information about Andorians and Eenar, generated by Sarikvaster for his hybrid character, Ensign Sarik Vaster.

Physiology

Genetics

The gender determining [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 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 [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.

	S	T
S	SS	ST
C	SC	CT

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.

Reproduction

Andorians require 4 individuals to procreate.
