Adipose tissue (AT) is a multi-depot organ in mammals and is formed in specific locations to meet the requirements of organism development. There are two main regional AT depots: subcutaneous and visceral. AT from various depots differs in composition and function. Based on the function, AT depots can be further classified as white and brown AT. Revealing the composition feature of AT depots will provide valuable information for further research on the fat deposition patterns in buffalo.

In this study, κ-casein (CSN3) and lactoferrin (LTF) genes were studied firstly in Turkish donkeys. PCR-RFLP and DNA sequencing of these gene regions were performed. CSN3 and the LTF gene had no enzyme recognition sites with PstI, DraII and MboI restriction enzymes in all of the studied samples. However, the LTF gene was only distinguished with EagI restriction enzyme and three genotypes were identified. The G allele was predominant in the LTF-EagI gene in the studied Turkish donkey populations.

The micronucleus (MN) test is a common tool used to evaluate cellular genetic instability at the chromosomal level. To evaluate genetic material stability in selected Canidae species, the MN test was performed. The interspecific hybrids differed from the other fox species in MN percentage. The chromosome polymorphism had little effect on genetic material stability in the blue and silver fox cells and significantly increases chromosomal damages in interspecific hybrids somatic cells.
