Does anyone understand how to write the genetic codes of hamsters?
I'm trying to understand how to write the genetic codes (i.e.: Aa, Wh, Bb) What order are you supposed to put them in and how do you know what genes two starter hamsters have in them, if they were from a pet shop? Do you just base it on what the hamster looks like and begin writing up geneotypes for their offspring? I understand how genetics works until I get to this point. Please help.l

The Genetic Code is far too complicated. The human/animal genotype written out would cover millions of miles. To determine certain characteristics though, I say use a punnet square. The Genetic Code is always written in alphabetical order (i.e.: AaBBCcddEe, etc). To determine its phenotype (what it will look like) pick out certain traits such as color. With the dominant phenotype, you will not be able to determine whether it is homozygous or heterozygous unless you know what the parents genotypes are. Use a simple Punnet Square and take both the parents genotypes. Say the dad is Black dominant (B) and the mom is brown recessive (b). We can automatically assume that the mother would be (bb) because she is recessive and the only way recessive traits are expressed is if their genotypes are homozygous recessive. The dad on the other hand could be (BB) or (Bb). Therefore, the Punnet Square will be incomplete (B_ x bb) from the offspring, you can determine the father's genotype. If all are black then he is (BB), if half are black and half are brown, he is (Bb). SO to determine what the offspring will look like, take the charachteristics of the parents and do a punnet square and get a percentage (1/2 black, 1/2 brown). If you are looking for more than one charachteristic, do the Punnet Square as well and multiply the percentages of what you want. The percentage you get from that will represent the chance you will get one that looks like that. If you have any more questions, or are looking for a more specific answer, let me know! :)
