The phrase "and the second population" is correct and usable in written English.
It can be used when referring to a specific group or category in a discussion, particularly in contexts involving comparisons or studies.
Example: "In our research, we analyzed the first population for trends, and the second population showed significantly different results."
Alternatives: "and the second group" or "as for the second population".
The majority of the population is at the index around −1, and the second population with a spectral index close to −1.5 appears.
One population would be silenced alleles that are readily reactivated by TSA treatment, and the second population would be alleles that are more stably silenced and fail to restore HPRT expression after TSA treatment.
This observation was consistent within the three replicates from the first population and the second population.
Two levels of mtDNA analysis, the first involving phylogeography, and the second population history, allowed us to evaluate how females have contributed in shaping the mtDNA pool of southern African Khoe-San and some Coloured populations.
To evaluate this hypothesis, we first performed the MKT, defining the first "population" as that of viruses found in swines, and the second "population" as that of viruses found in humans.
The results of the early life span assay described previously (see Figure 1E) clearly showed that there were two populations of neonates carrying ≥50% ∆mtDNA in their tail; the first population showed death phenotypes in the first month after birth, probably due to PS-like phenotypes; and the second population was able to escape early death.
These 3 populations differed in many ways; one population consisted of 753 genetically related individuals [16] of which 63 suffered from asthma, another population consisted of 344 children with asthma (The Freiburg population) and the third population consisted of a mix of 99 children and adults with asthma recruited from an asthma clinic (Chicago population) [6].
With the 142 SEER cases reported here, this is the largest series reported to date and the first population study of mammary NEC.
The second population was located in a second site in the municipality of La Paz San Bartoloo town) and the third population of the third site was located in the municipality of Los Cabos Santiagoo town) both near the area limit of the biosphere reserve La Laguna, B.C.S., México.
If we let P11 represent the frequency of allele in the first population and P21 the frequency of the same allele in the second population, then δ = |P11−P21|.
FvdK made a large contribution to the design and performance of the second population-based seroprevalence study, and helped to draft the manuscript.
