Sentence examples for fertile lineage from inspiring English sources

If, for example due to meiotic errors, the hybrid doubles its chromosomes, it can develop into a new, fertile lineage that is instantaneously reproductively isolated from its parents (but see e.g. [ 3]), so called allopolyploidy.

Consequently, we apply this approach to infer the expected time to extinction by Muller's ratchet for lines of C. elegans under the assumption that outcrossing stopped immediately upon the origin of the self-fertile lineage.

All genetic mosaics that lost kin-1 function in somatic gonadal lineages were fertile (Table 2).

We observed that all genetic mosaics that lost kin-1 function in somatic gonadal lineages were fertile (Table 2).

These studies demonstrate that fertile and viable hybrid lineages can be obtained after only a small number of generations (<10) of selfing and/or backcrossing, even if the F1 hybrids were almost completely sterile.

Chengia laxispicata gen. et sp. nov. provides a missing link between archetypal fertile organs in the crown lineage of the Gnetales and compound female cones of the extant Ephedraceae.

In contrast, by the F5 generation, hybrid-control lineages continued to produce significantly fewer fertile pollen grains (70%) than wild-control lineages and hybrid-long lineages produced even fewer (63.8%; F2,3.6 = 8.01, P = 0.041).
