Sentence examples for migration and interbreeding from inspiring English sources

This mechanism can only work if migration and interbreeding between the ancestral population and the new founder population is extremely low or even nonexistent: some population geneticists think even "extremely low" migration and interbreeding are enough to prohibit speciation by founder effects.

Rather, the data confirm a history of gene flow between populations, supporting migration and interbreeding between these seemingly disparate groups.

A fine-scale genetic study of common fungal species associated e.g. with Alnus glutinosa [ 15] in its glaciation refugia such as Spain, North Africa, Corsica, Balkans and Turkey, would help quantifying local host-dependent diversification processes in fungi, migration and interbreeding processes at a continental scale, and extrapolate them to more ancient speciation events.

When populations diverge in sympatry or parapatry, they must overcome the exchange of genes due to migration and hybridization (interbreeding) if speciation is to proceed.

When populations diverge in sympatry or parapatry, they must overcome the homogenizing effects of gene flow due to migration and hybridization (interbreeding) if speciation is to proceed.

Rather, an individual's genome reveals his or her ancestral lineage, which is a function of the migrations and interbreeding among population groups.

The genetic variation that is necessary for a species to adapt to the physical environment and to other organisms arises from new mutations within populations, the recombination of genes during sexual reproduction, and the migration of and interbreeding with individuals from other populations.

Overall, the recurrent migrations, admixture, and interbreeding events shaped the autosomes of modern populations into mosaics of ancient and recent alleles harbored in haplotypes that vary in size but not in the building blocks themselves.

Because the Apollos live in small local populations, thus having no contact with each other, coupled with their strong stenotopic nature and weak migration ability, interbreeding between populations of one species practically does not occur; by this, they form over 600 different morphs, with the size of spots on the wings of which varies greatly.

The startling decline in wild Scottish salmon is being blamed on pollution and interbreeding between wild and farmed salmon.

Thus, the Aryan race had to be maintained and improved, and interbreeding with 'less valuable races' would inevitably lead to an extinction of the Aryan race.
