Genetic variation and relationships among eight Indian riverine buffalo breeds
Analysis of molecular variance refuted the earlier classification of these breeds proposed on the basis of morphological and geographical parameters and will be useful for development of rational breeding and conservation strategies for Indian buffaloes.
Mitochondrial DNA analyses of Indian water buffalo support a distinct genetic origin of river and swamp buffalo.
This study sequenced the mitochondrial D-loop region and cytochrome b gene of 217 and 80 buffalo respectively from eight breeds/locations in northern, north-western, central and southern India and compared the results with published Mediterranean and swamp buffalo sequences.

The data are consistent with the available archaeological information in supporting the proposition that the river buffalo was likely to be domesticated in the Western region of the Indian subcontinent, specifically the present day breeding tracts of the Mehsana, Surati and Pandharpuri breeds.

The phylogenetic analysis using complete mitochondrial genome sequences unambiguously suggested that gaur is the maternal ancestor of domestic mithun, and clearly distinguished the three sub species of B. gaurus i.e. B.gaurus gaurus, B.Gaurus readei and B. Gaurus hubbacki.
Mitochondrial DNA Variability of Domestic River Buffalo (Bubalus bubalis) Populations: Genetic Evidence for Domestication of River Buffalo in Indian Subcontinent
The phylogenetic analyses of the study along with the archaeological evidence suggest that the river buffalo was domesticated in an atypical manner involving continuous introgression of wild animals to the domestic stocks in Indian subcontinent prior to mature phase of Indus Valley civilization.
Breeding Behaviour and Embryonic Development of Koi Carp (Cyprinus carpio)
Induced breeding experiments of Nikishigoi (koi carp), Cyprinus carpio were conducted in mature males and females by administrating a single intramuscular injection of ovaprim at a dosage of 0.3mL/kg weight, and the hatchlings appeared just like an adult in all respects except sexual maturity.
Cell-to-Cell Stochastic Variation in Gene Expression Is a Complex Genetic Trait
It is found that noise was highly heritable and placed under a complex genetic control, and the complex genetic architecture of noise buffering couples genetic to non-genetic robustness and provides a molecular basis to the probabilistic nature of complex traits.

The phylogenetic assessments of Indian mithun along with other Bos species showed a very close genetic relationship of Indianmithun with gaur suggesting that IndianMithun might have evolved from gaur.
Hormonal manipulation of sex in stinging catfish Heteropneustes fossilis (Bloch)
Two masculinizing hormones and two feminizing hormones were tested for their sex manipulation role and invariably produced intersex individuals characterized by intermingling of spermatogonia and oocytes in the same gonad.
Length–weight relationships of Channa punctata (Bloch, 1793) from Western Ghats rivers of Tamil Nadu
Results of the present study show that there is no significant difference in the length–weight relationship as a function of sex in the Siruvani, Vellaru and Cauvery populations, whereas there is a significant difference between males and females in the Tamirabarani population, indicating non-homogeneity of these relationships.
