Social network and instant messaging app Kik is making a small, crucial change to its platform today: new messages from strangers now show up with both avatar and any pics and content contained therein blurred by default, allowing users to opt to see that content once they deem it safe or appropriate.
The mean polymorphism information content (PIC) for all the loci was high (PIC > 0.7), suggesting that these microsatellite markers could be useful for population genetics and diversity studies.
Polymorphism Information Content (PIC) values ranged from 0.087 to 0.50 with an average PIC value of 0.30.
Among the 6 wild populations, XXL showed the highest mean number of alleles (MNA), mean AR, mean HE, and mean polymorphic information content (PIC) (MNA = 10.8; AR = 8.324; HE = 0.856; PIC = 0.832).
To compare the efficiency of primers and polymorphism information content (PIC), a measure of allelic diversity at a locus was calculated using online PIC calculator software (http://www.liv.ac.uk/~kempsj/pic.html) using the following formula: (1) PIC = 1 − ∑ i = 1 n p i 2 − ∑ i n − 1 ∑ j = i + 1 n 2 p i 2 p j 2, where p i is the frequency of the ith allele and n is the number of alleles.
Polymorphism information content (PIC), a measure of the informativeness of a genetic marker, was also calculated for each marker as follows; PIC = 1 − ΣPi, where Pi is the frequency of the ith allele in the examined genotypes.
For autosomal loci, Polymorphic Information Content (PIC) was 2.6% higher for sequence-based data.
The novel polymorphic microsatellites produced an average of 4.9 alleles/locus, an average observed heterozygosity of 0.4296 and an average PIC (polymorphism information content) value of 0.4483.
The informativeness of markers was assessed by calculating polymorphic information content (PIC; Botstein et al. [1980]) using PowerMarker V3.0 (Liu and Muse [2005]).
In comparison to CE analysis, Observed and Expected Heterozygosity, Polymorphic Information Content (PIC) and Genetic Diversity also presented higher values when the alleles were analyzed based on their sequence.
