The allotetraploid hybrid fish (4nAT) that was created in a previous study through an intergeneric cross between red crucian carp (Carassius auratus red var., ♀) and common carp (Cyprinus carpio L., ♂) provided an excellent platform to investigate the effect of hybridization and polyploidization on the evolution of 5S rDNA.

In mammals, multigenerational environmental effects have been documented by either epidemiological studies in human or animal experiments in rodents. Whether such phenomena also occur in birds for more than one generation is still an open question.

The merging of two diverged genomes can result in hybrid offspring that phenotypically differ greatly from both parents. In plants, interspecific hybridization plays important roles in evolution and speciation. In addition, many agricultural and horticultural species are derived from interspecific hybridization.

A group of animals that cannot interbreed with animals from another group is often taken as the definition of a ‘true’ species. However, a suite of recent studies suggests that the rare event of hybridization, that is, the production of viable offspring by the interbreeding of individuals from two such species, can facilitate adaptation through the process of genome ‘introgression’.

Heterosis breeding is the most useful method for yield increase around the globe. Heterosis is an intriguing process to develop superior offspring to either parent in the desired character. The biomass vigor produced during seedling emergence stage has a direct influence on yield heterosis in plants. Unfortunately, the genetic basis of early biomass vigor in cotton is poorly understood.

Peromyscus are the most common mammalian species in North America and are widely used in both laboratory and field studies. The deer mouse, P. maniculatus and the old-field mouse, P. polionotus, are closely related and can generate viable and fertile hybrid offspring.

Genomic imprinting results in the expression of parent-of-origin-specific alleles in the offspring. Brassica napus is an oil crop with research values in polyploidization. Identification of imprinted genes in B. napus will enrich the knowledge of genomic imprinting in dicotyledon plants.

There has been increasing interest in coalescent models which admit multiple mergers of ancestral lineages; and to model hybridization and coalescence simultaneously. Hybrid-Lambda is a software package that simulates gene genealogies under multiple merger and Kingman’s coalescent processes within species networks or species trees.

The phenomenon of heterosis is critical to plant breeding and agricultural productivity. Heterosis occurs when F1 hybrid offspring display quantitative improvements in traits to levels that do not occur in the parents.

In the present investigation a study was conducted to assess the nature and magnitude of yield attributing characters. The inheritance of the character viz; plant height and flower to pod ratio was controlled by additive gene action. The rest of the nine characters under the control of non additive gene action therefore the heterosis breeding is recommended to exploit the benefit of hybrid vigor. Heritability is good index of the transmission of character from parents to their offspring.

Thirty castor hybrids were developed by crossing three pistillate lines with ten male parents in a line × tester mating design during rabi, 2016-17. The hybrids along parents were evaluated during kharif, 2017-18 for variability and combining ability. The analysis of variance for nine economically important characters indicated significant differences among the genotypes, implying presence of wide diversity in the material studied.

In this study, the combined ability effects and heterosis were determined for number of days to anthesis (AT), plant height (PH), fertile tillers plant–1 (FT), spike length (SL), spikelets spike–1 (SS) and grains spike–1 (GS), 1000-kernel weight (TW).
