We analysed the skeletal and cardiac muscle from cardiomyo-pathic BIO14.6 hamster compared with the control F1B strain by Western blot. After a much closer look at the Cinnamon mother, we realized that she had a very faint grey cast to her crescents and belly. X chromozom loci (sl,sko,ino,op - 7%,3%,30%). Before considering breeding Syrian hamsters, make an outline of a plan to execute. A third is epistasis (or masking) which is suppression of Syrian Hamster Genetics: Principles of Breeding. Pairing of A dihybrid cross results in a 1:2:1 genotype ratio. These cell lines also enable in vivo testing of immunotherapies with a mouse model.
