THE theory of genetic recombination by the formation of hybrid DNA 1 postulates that a recombinational event involves breakage of single DNA nucleotide chains (primary breaks), and rejoining by ...

A popular explanation is the Dobzhansky-Muller (DM) model of hybrid incompatibility. In the ancestral population, the genotype is AA BB. When the population is split into two, A evolves into a in ...

In the world of animal breeding, hybrid animals are a fascinating mix of nature and human effort. These animals are created ...

However, they frequently encounter a major obstacle: hybrid seed failure. This reproductive barrier often prevents closely related species from producing viable seeds. A new study published in ...
