Abstract

A palaeogenetic analysis has been undertaken on the pre-Hispanic settlement of Los Amarillos (Regional Development Period, Jujuy Province, Argentina) to reconstruct kin relationship between individuals buried in two domestic areas. The aim of this study was first to genetically characterize the relationships between the individuals buried within the same funerary structure and, secondly, to correlate these genetic data with archaeo-anthropological data to discuss the burial practices and social organization of the Los Amarillos community. An analysis of both uniparental (mtDNA and Y-chromosome) and biparental (autosomal STRs) genetic markers was conducted on eighteen individuals recovered from three different burial structures. The very good DNA preservation contributed to characterize 13 mitochondrial haplotypes, 5 Y-chromosomal haplotypes and 11 complete autosomal STR profiles. The kinship analysis revealed that the domestic areas were used as family graves. Furthermore, they reveal that a maternal lineage is shared by a majority of the studied individuals from different sectors, suggesting matrilocal practices. [ABSTRACT FROM AUTHOR]

Abstract

The social construction of human categories: Ásta: Categories we live by: The construction of sex, gender, race, and other social categories. Ásta argues that sex is an institutional property, while gender is a communal property. Ásta's stance that gender is a communal property implies that gender is highly variable because the socially significant properties used for gender conferral I change i in different contexts, e.g., a gay bar versus a family reunion.

Abstract

Following the chromosome through history: Soraya de Chadarevian: Heredity under the microscope. After human chromosome counts had been rendered reliable, it soon turned out that conditions with supernumerary or missing X or Y chromosomes were among the most frequent "chromosome diseases." Chapter three is devoted to the X and Y "sex" chromosomes, the diploid chromosome pair XX associated with the female, the XY pair with the male phenotype. [Extracted from the article]

Abstract

When the centromere is in the middle of the chromosome (a metacentric chromosome), there are two long arms and when the centromere is located at the top of the chromosome, one arm is shorter (an acrocentric chromosome) or barely there (a telocentric chromosome). Robertsonian translocations occur when the long arms of two non-homologous telocentric or acrocentric chromosomes fuse at the centromere to form a new metacentric chromosome and the short arms are lost. In simple heterozygotes metacentric chromosomes pair with each homologous telocentric chromosome, forming a chain of three chromosomes. Chromosomal asynapsis directly disrupts the normal silencing of the sex chromosomes and it may be the expression of the sex chromosomes during male meiosis that causes hybrid sterility (Bhattacharyya et al. 2013; Bhattacharyya et al. 2014).

Abstract

Chapter 4 introduces genetic association studies involving single nucleotide polymorphisms (SNP), haplotypes, multiple SNPs, and genome-wide SNPs, often referred to as genome-wide association studies (GWAS). Omic Association Studies with R and Bioconductor by Juan R González and Alejandro Cáceres is an introductory book geared toward those looking for step-by-step examples on data analysis with existing tools and a high-level overview of biological interpretation. Specifically, this chapter shows how to annotate association analysis to reference genomes, map the results to curated biological, disease, and chemical interaction databases, and assess if the overlap to the databases is significant.
