Abstract

The identification of the individual phenotypic characteristics, most often the color of hair, eyes, and skin, applies both in forensic practice and in the research of ancient DNA. There are several types of approaches and protocols that can be applied according to the objectives and nature of the DNA to be investigated on the research sample. The main aim was the introduction of a method for the detection of rs12913832 polymorphism of the HERC2 gene, which is considered to be the strongest marker of the prediction of the eye color. Real-time PCR using a target-specific TaqMan® probe was used as it is the most suitable method for detecting polymorphism. This predesigned probe is characterized by a very short length of the sequence, making it ideal for research in ancient DNA. DNA sequences are often very short because of degradation and fragmentation. Allelic discrimination was chosen to detect the genotype. For the analysis, the skeleton material from the burial site Znojmo-Hradiště (Great Moravia Age) was used. From the whole set of 20 samples, 19 of them were successfully analyzed and genotyped. None of the detected genotypes was identified as the homozygous TT, which is characteristic for very dark shades of eyes. In contrast, the heterozygous assembly was detected in most samples. A genotype of TC, which is common in individuals with brown or hazel eyes, was determined in 15 samples. The light shade and the corresponding CC genotype were then determined in 4 individuals.

Abstract

In humans, as in animals, associations or correlations between morphological and personality traits can be observed. Some of the most conspicuous and well describable morphological traits in humans are eye color, hair color, body height and body mass index (BMI). These traits can correlate not only with temperament or character, but also, for example, with intelligence. Relations between morphology and personality can have an origin on a genetic or an environmental level. The human psyche, which can be influenced by social factors, can also have a role in the chain of causes and consequences. In this study, known relations between morphological traits and personality are discussed and mechanisms which could be responsible for these relations are mentioned. This study also focuses on the possible role of the environment which could explain some associations between the traits. Further, there is an attempt to identify environmental factors contributing to the morphological and personality traits which could therefore be a cause of some correlation between these traits.

Abstract

In bachelor's thesis I deal with the influence of various factors on the color of hair and eyes of the European population. In Europe, many still find blond and light eye colour population despite there is much darker colored populations. Here are some of the mechanisms causing maintain high polymorphism in the European population. The first part of bachelor's thesis focuses on a brief description of the structure of the European population. The thesis also discusses the genetic determination of hair and eyes, its diversity and the differences of the population from the populations of Asia and Africa. In the next section, we discuss the emergence and spread of recessive alleles light eye color a blonde in Europe, particularly northern Europe. The following is a description of the mechanisms influencing the propagation and conservation of recessive alleles. In the penultimate chapter describes the relationship between the morphology of the face and eye color, and the last chapter summarizes the effects mentioned in the previous chapters and their effect on the length of the relationship between partners.
