Red, yellow, or orange variants occur in many species.
The word "keep" and its variants occur forty-seven tines iNorthrth of Boston"; some of Frost's greatest poems, from later in his career ("The Most of It" and "Directive" both come to mind), turn on that weirdly abundant little word.
In the megathermal class, related to hot equatorial and tropical climates, two main variants occur; discharge is powerfully sustained throughout the year, usually with a double maximum (two peak values), but in some areas with a strong single maximum.
Second, those variants occur at different frequencies in the general population.
Heteroplasmic and homoplasmic sequence variants occur in the mitochondrial genome in patient tumors.
The next filter is population-specific exome data, because some variants occur only in certain sub-populations and are not disease-causing.
As such, they pose a peculiar problem for infant language learners: These variants occur in the ambient language, but they are not used to encode lexical contrasts.
At the same time, admixture mapping can be more powerful, and can achieve higher mapping resolution than traditional linkage studies, provided that the underlying trait variants occur at sufficiently different frequencies in the ancestral populations.
Ogawa 小川尚義 (1907) and Ang 洪惟仁 (1997, 2003) argued that the two variants occur in a dialect-dependent fashion, with [dz] being more commonly found in the 泉 Chôan dialect and [z] being more frequently observed in the 漳 Chiang and the Mix dialect.
To test this, we investigated variants occur at amino acid residues responsible for protein function.
We also measure the likelihood of amino acid substitutions and the degree of residue conservation where variants occur.
