The unifying physical characteristics of Negritos are short stature, curly hair, and dark pigmentation. Although short stature and dark pigmentation can be prevalent among some […]

Diploid Genotyping Low to Medium Coverage Ancient DNA – Part 1

Diploid Genotyping Low to Medium Coverage Ancient DNA – Part 1

OVERVIEW The overwhelming majority of published ancient DNA (aDNA) are pseudo-haploid genomes. This study focuses on the suitability and accuracy of these pseudo-haplodized aDNA genomes for various types of downstream analysis, such as those involving admixture allele frequency studies, as well as Identity-by-Decent (IBD) analyses and analyses using formal methods. The accuracy of pseudo-haploid aDNA genomes is also compared their diploid counterparts which were processed […]

For example, what does it mean if you are say from Pakistan, and the […]
