Genomic selection is an accurate and efficient method of estimating genetic merits by using high-density genome-wide single nucleotide polymorphisms (SNPs).In this study, we investigate an approach to increase the efficiency of genomic prediction by using genome-wide markers. The approach is a feature selection based on genomic best linear unbiased prediction (GBLUP),which is a statistical meth...

Humans are characterized by an unusual level of prosociality. Despite this, considerable indirect evidence suggests that biological kinship plays an important role in altruistic behaviour. All previous reports of the influence of kin selection on human altruism have, however, used correlational (rather than experimental) designs, or imposed only a hypothetical or negligible time cost on partici...

This article explores the relationship between kinship institutions and sex ratios in India at the turn of the twentieth century. Because kinship rules vary by caste, language, religion, and region, we construct sex ratios by these categories at the district level by using data from the 1901 Census of India for Punjab (North), Bengal (East), and Madras (South). We find that the male-to-female s...

This study uses the case of transracially adopted multiracial adults to highlight an alternative family context and thus process of African American enculturation. Interpretive analyses of interviews with 25 adult multiracial adoptees produced 4 patterns in their bicultural identity formation: (1) claiming whiteness culturally but not racially, (2) learning to "be Black"-peers as agents of encu...

This paper examines the use of both mitochondrial DNA and Y-chromosomal DNA in the study of kinship groups, particularly those from ancient burial sites. The characteristics of both types of DNA that make them suitable for such endeavors as well as methods of application to kinship studies will be outlined. Additionally, specific examples from modern, ancient, and other non-human primate resear...

Three experiments were carried out to investigate whether the the kinship concept had spatial representations along up-down (Experiment 1), left-right (Experiment 2), and front-back (Experiment 3) orientation. Participants identified the letter P or Q after judging whether kinship words were elder or junior terms. The results showed that participants responded faster to letters placed at the to...

Family is special. People avoid sexual contact with close relatives, but at the same time are highly beneficent toward them. Such discriminatory behavior is guided by a set of psychological mechanisms, heuristics that facilitate evolutionarily adaptive behavior most of the time but may lead to over-perception of kinship under specific circumstances. In this chapter, we describe psychological me...

Kinship is an important dimension of politics throughout the Middle East and, specifically, in Jordan. At level face-to-face negotiations, three kinds kinship (common descent, affinity, ritual kinship) are invoked Jordan to garner support from actor’s kin and create political ties. large-scale organizations – such as tribes appeals made norms mobilize members each organization enhance group sol...
