Heredity of colouring in rabbits
 HOZDOVÁ, Lenka
This bachelor thesis is focused on the practical verification of the laws of heredity in fur coloration during mating of rabbits Californian black rabbit and Viennese blue rabbit. Coloration of these breeds are white with black marks on the ears, nasal mask, legs and tail in Californian black rabbit and cloak blue coloration in Viennese blue rabbit. In subsequent generations there were also individuals discolored by either parent and were cloak black. According to the analysis of genotypes of both breeds, this phenomenon was anticipated and the further cross-breeding of the offspring of the F1 generation began to re-emerge from the individuals of the same coloration as the original two purebred breeds. Repeated crossings of parent breeds were carried out, as well as the crossing of F1 and F2 generations in different combinations. Based on the genotypes of the parents, the coloration of individuals of all types of litters was predicted and subsequently these ratios were verified by a mathematical method called "Chí quadrate test". All these ratios were consistent with the assumptions and the objective of the work was therefore verified.
