Speciation within a continuous population without physical barrier is:

Sympatric reflects key principle in quiz on section e solved pyqs, where evolutionary mechanisms shape genetic variation and adaptation. In this context, Sympatric aligns with experimental and theoretical evidence from population genetics, behavioral ecology and molecular phylogeny. Textbooks like Campbell Biology, Futuyma Evolution and Hartl Principles illustrate supporting data. Understanding why Sympatric fits helps integrate natural selection, environment.

Postzygotic isolation acts:

Postzygotic barriers act after fertilization reducing hybrid viability or fertility, including hybrid inviability where embryos abort, hybrid sterility where mule with 63 chromosomes cannot produce functional gametes due to mismatched pairing, and hybrid breakdown where second generation has low fitness. These arise from Dobzhansky-Muller incompatibilities accumulating after divergence. Mule exemplifies sterility. Therefore After fertilization represents postzygotic isolation maintaining species boundaries after mating. This concept integrates genetics, ecology and molecular evidence, frequently tested in NEET, GATE and CSIR-NET, highlighting links between genotype, phenotype and environment.
