Sentence examples for dominance hypothesis from inspiring English sources

The dominance hypothesis invokes the masking of deleterious recessive alleles of one parent by dominant (or partially dominant) alleles of the second parent, to explain the hybrid vigor of the F1 (Davenport 1908; Bruce 1910; Jones 1917).

This chapter proposes the offspring dominance hypothesis (ODH) as a potential solution.

Behavioral results were consistent with the affective task dominance hypothesis: participants were slower to switch to the affective task, and cross-task interference was strongest when participants tried to switch from the affective to the non-affective task.

The dominance hypothesis states that alleles causing hybrid dysfunction are partially recessive, and the heterogametic sex (XY or ZW) is fully exposed to the deleterious effects of these recessive alleles [71].

The partial dominance hypothesis focuses on the role of homozygosity of rare, recessive/partially recessive deleterious mutations.

Our results provide evidence for the contribution of deleterious mutations to heterosis via complementation, consistent with the dominance hypothesis.

Among non-additively expressed genes, both over-dominant and under-dominant genes are rather abundant, supporting in part the over-dominance hypothesis for rice heterosis [ 34].

Specifically, the dynamic-dominance hypothesis of handedness [40], [52] states that the left hemisphere is more involved in the feedforward control (via internal models) of arm dynamics, whereas the right hemisphere is more specialized in the positional feedback control, at least for right-handed people.

The second is the over-dominance hypothesis, which states that a heterozygous locus in an F1 hybrid will perform better than either homozygous locus in parents; therefore, heterozygosity per se causes heterosis.

In particular, stingless bees appear to avoid resources occupied by dominant species, thereby steering clear of conflict (the dominance motivation hypothesis).

Under the dominance motivation hypothesis, if eavesdropping decisions were based solely on relative dominance, we would have seen attraction by T. hyalinata foragers and avoidance by T. spinipes foragers to heterospecific recruitment pheromone.
