Andorian/Gender and Reproduction: Difference between revisions

Removed a section which immediately contradicted the one above, and implied Andorians can only have children during puberty. It didn't come from a canon source, contradicts what soft canon there is, and is not what our simmers are writing (not to mention a little troubling considering we're talking young teenagers!).

'''Andorians''' have 4 genders, 2 of which resemble males and 2 of which resemble females. These are called ''Thaan'', ''Chan'', ''Shen'' and ''Zhen''. This can result in some confusion among outsiders. Sometimes it is difficult to tell what gender an Andorian is on sight. This is especially true as a ''chan'' can appear to be feminine and a ''shen'' can appear to be masculine. | '''Andorians''' have 4 genders, 2 of which resemble males and 2 of which resemble females.

===Reproduction | ==Genetics== | ||
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 transferred to the Zhan, it is to developed to the point that it will not accept new genetic material into all of its cells. | |||
==Reproduction== | |||
In order for Andorians to produce a child it takes 1 of each [[MA:gender|gender]]. They each have a specific role to play. This starts with the ''Thaan'' fertilizing the ''Shen'''s egg. Then the ''Chan'' has to fertilize it next. The reason for this is that the 2 males, the ''Thaan'' and the ''Chan'' each have 1/4 of the necessary genetic material needed to create a child. The ''Shen'' has the other half with in her egg. | In order for Andorians to produce a child it takes 1 of each [[MA:gender|gender]]. They each have a specific role to play.

Once the egg has developed into a fetus it has to be transferred to the ''Zhen''. This is because only the ''Zhen'' can nurse the young. When the ''Shen'' becomes pregnant special glands along the ''Zhen''<nowiki>'</nowiki>''s'' spine become active. They will secrete a membrane that forms a pouch around the lower torso. At this time the 4 teats on the ''Zhen''<nowiki>'</nowiki>''s'' lower abdomen will start to form milk. Unlike [[Human|Humans]] these do not result in rounded breasts. The inner lining of the pouch produces a thick gel that will protect the baby while it nurses until it is mature enough to survive outside of the pouch. | Once the egg has developed into a fetus it has to be transferred to the ''Zhen''.

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 bond mates will then assist by rubbing her with oils and help to peel off the remains of the now useless pouch. | |||
Due to increasing difficulties with conception and fewer viable pregnancies, Andorians marriages are arranged at a young age based on genetic compatibility, and choosing one's own bond mates is rare. The marriage itself usually takes place in early adulthood, and because of the limited window of fertility, the bond group will try to conceive as many children as possible during this period. | |||
==Notes== | |||
===Declining population=== | |||
Due to the requirement of four parents in the reproductive cycle and the usual production of less than four offspring, the Andorian species is in decline - the Andorian Science Institute has been hard at work exploring possible solutions to this problem. | |||
The most promising form of research has been into altering the Andorian [[MA:chromosome|chromosome]] #17. It is believed that by altering this chromosome, they could increase the length of fertility considerably, thus increasing the number of years during which conception would be possible. | |||
Another area of research is into the possibility of altering the way the [http://en.wikipedia.org/wiki/Gamete gametes] divide in the body. If successful, this would make both the ''Thaan'' and the ''Chan'' fully functional males with viable sperm. The long term implications for them as a race would be the elimination of the need for paired quads as their would eventually only be two sexes. However this research has produced great controversy within the Andorian society. It goes against all their customs and traditions. Many Andorians are outraged by this research and feel that any and all work into altering the four [[MA:gender|sexes]] should be stopped and destroyed. | |||
===Saf=== | ===Saf=== | ||
Saf is a aphrodisiac and psychoactive chemical that is refined from a native Andorian plant. It does not replicate well and only grows successfully on their native homeworld of [[Andoria]]. It is used by Andorians during sex as it provides a number of benefits when it comes to pleasure and sexual function. Normally only sanctuary priests and priestesses are allowed to dispense it to bonded groups. It is generally only available by medical prescription. | |||
It is illegal to possess ''Saf'' offworld and can be fatal to some non-Andorians. It has been used by some as a recreational drug and is still available on the black market. The [[Cardassian|Cardassians]] were known to use it during the [[Bajoran]] Occupation. | It is illegal to possess ''Saf'' offworld and can be fatal to some non-Andorians.
