More accurate assessment of
gene frequency of bTT in the population provides solid data about the health burden posed by the disease and is of great help to plan control programs for b-thalassemia in the area.12

The high
gene frequency is due to founder effects and high incidence of consangious marriages in the above populations.
The
gene frequency for spe C (24%) was comparable with earlier study (9,11).
This is the first study for the molecular characterization of the [alpha]-thal
gene frequency in healthy individuals from the Setif region.
As acceleration a is a function of the net force applied to a body with mass m (according to Newton's law, a = F/m), so change in
gene frequency is a function of external environmental 'forces' and phenotypic properties of organisms (crudely analogous to mass.)
The assumption then--and a plausible one--is that ethnic groups differ in susceptibility and
gene frequency and finding two ethnic-specific diseases together says little.
For each individual fish--five beans are randomly grabbed from the cup, coded, and recorded on the
gene frequency chart (Figure 2), and placed into the next generation cup.
"New technologies allow scientists to spot changes in wildlife
gene frequency quickly and affordably," said Timothy Beardsley, editor in chief of BioScience magazine.
Gene frequency measures the frequency of a particular population of a particular gene relative to other genes at its locus.
The
gene frequency ranges from 0.01 in central Thailand, 0.033 in northern Thailand, 0.05 in Laos, to 0.05-0.06 in northeastern Thailand (2, 3).
They describe the evidence for evolution in fossils, rocks and drug resistance, examine how evolution works (DNA, genetic variation and
gene frequency, mate choices and coefficients of relatedness), the scale and products of evolution and the role of evolution in our daily lives.
