A new theory of attraction and liking based on kin selection suggests that people detect genetic similarity in others in order to give preferential treatment to those who are most similar to themselves. There are many sources of empirical and theoretical support for this view, including (1) the inclusive fitness theory of altruism, (2) kin recognition studies of animals raised apart, (3) assort...

The paper proposes an approach using genetic algorithm for computing the region based image similarity. The image is denoted using a set of segmented regions reflecting color and texture properties of an image. An image is associated with a family of image features corresponding to the regions. The resemblance of two images is then defined as the overall similarity between two families of image...

We present genetic similarity theory (GST), which incorporates the kinselection theory of altruism under a more general principle. GST states that a gene ensures its own survival by acting so as to bring about the reproduction o f any organism in which copies of itself are to be found. Rather than behaving altruistically only toward kin, organisms are able to detect other genetically similar or...

The poor information available on variation of Ascochyta blight fungus is the most important factor limiting chickpea breeding programs for resistance to blight disease. In this study, efforts were made to detect genetic variation of the pathogen in Iran. The RAPD marker was employed to evaluate 26 isolates collected from 16 provinces. Twelve random primers were used to analyze genomic DNA of t...

When employing a similarity function to measure the similarity between two cases, one large problem is how to determine the feature weights. This paper presents a new method for learning feature weights in a similarity function from the given similarity information. The similarity information can be divided into two kinds: One is called qualitative similarity information which represents the si...

micropropagated plantlets derived from three different grape rootstock genotypes namely, dogridge (vitis champini), so4 (v. berlandieri×v. rupestris) and ari-h-144 (v. vinifera×v. labrusca) were subjected to randomly amplified polymorphic dna (rapd) and inter simple sequence repeats (issr) analyses in order to evaluate their genetic stability and/or detect likely existing variations among in vi...

iran, with a long history of apricot cultivation is one of the most important apricot producers in the world. centuries of sexual reproduction via seed, have developed many divergent variations of apricots in iran. however, unfortunately there is no comprehensive report available concerning its diversity and genetic make-up. in this study, 39 iranian apricot cultivars as well as accessions, nat...

The question of whether animals possess 'cultures' or 'traditions' continues to generate widespread theoretical and empirical interest. Studies of wild chimpanzees have featured prominently in this discussion, as the dominant approach used to identify culture in wild animals was first applied to them. This procedure, the 'method of exclusion,' begins by documenting behavioural differences betwe...
