Abstract: The Frequencies of Blood types, alleles and genotypes of the ABO and Rh blood group system varies worldwide. Therefore, this study was conducted to get information on the frequencies of alleles, phenotypes and genotypes of ABO and Rh D blood group systems among the students of Amhara and Oromo ethnic groups at Sheno Secondary and Preparatory School, North Shewa Zone, Oromia Region. A total sample of 600 students from two ethnic groups were randomly selected and tested for ABO and R...
Abstract: ABO and Rh blood group systems in humans are two important molecular markers that are routinely analyzed prior to transfusion and medical treatment. The frequency of ABO and Rh blood group genotypes and alleles varies worldwide and are not found in equal frequency among ethnic groups. Therefore, This study was carried out with an aim to determine the allelic and genotypic frequencies of ABO and Rh blood groups among students of Hawariyat Preparatory School, Mihur Akilil Woreda, Sou...
Abstract: The frequency of ABO and Rhesus blood group vary geographically,ethnically and from one population to another. Some variation may occur with in one ethnic groups and within small country. This study was conducted to determine freqeuency of ABO and Rhesus blood group,phenotype, genotype,and allele among ethnic group Tigrean, Saho,and ,Erob people in Mekelle city Ayder Hospital Tigray, Ethiopia. A Total of 630 individuals were selected purposively among the patient of Ayder Hospital....
Abstract: Maize (Zea mays L.) is one of the most important cereal crops in Ethiopia. It is first in productivity among cereal crops and second in area of production. The experiment was conducted to determine the magnitude and extent of genetic variability; and the association between traits and their contribution to yield in maize genotypes. The field experiment was laid out in a 10x5 alpha lattice design with two replications. The analysis of variance showed genotypic mean squares were sign...
Abstract: Linseed (Linum usitatissimum L.) is one of the most important oilseed crops for industrial, food, feed, and fiber purposes. Genetic variability plays important role for development of improved varieties. The aim of this study was to characterize thirty-six linseed genotypes using yield, yield related traits and oil content to determine magnitude of genetic variability, and phenotypic and genotypic correlation between yield and yield components. The field experiment was conducted at...
Abstract: This study was aimed at identifying the distribution patterns of ABO and Rh-D blood group system alleles among Hirna primary and secondary schools in 2015/16 academic year. Six hundred volunteer students were involved to determine the ABO and Rh-D blood group phenotypes, and to estimate allelic, and genotypic frequencies of the blood groups. The blood sample was collected by qualified laboratory technicians using the standard clinical procedures with sterilized needle from each stu...
Abstract: The ABO and Rh blood groups are the most important blood groups despite the long list of several other blood groups discovered so far. The distribution of ABO and Rh blood groups vary worldwide and are not found in equal numbers even among ethnic groups. They are also associated with some important human traits. Therefore, this study seeks to assess the distribution of ABO and Rh-D blood groups and to determine if there is any relationship between these blood groups and anthropomet...
Abstract: Frequencies of phenotypes, alleles and genotypes of ABO and Rh-D Blood Group systems are known to vary worldwide geographically, ethnically and from one population to another. Therefore, this study was aimed at assessing the frequencies of phenotype, allele and genotype in ABO and Rh-D Blood group system in selected ethnic groups (Afar and Tigray) amongs tudents of Aba’ala Secondary School, Zone Two, Afar Region, Ethiopia based on their purposively to participate in the study. A ...
Abstract: The four blood types are known as A, B, AB, and O. Blood type A contains A antigen on the surface of red blood cells and B antibody on blood plasma. Type B blood contains the reverse combination. Serum of blood type AB contains neither antibody, but red cells in this type of blood contain both A and B substances. In type O blood, neither substance is present on the red cells, but the individual is capable of forming antibodies directed against red cells containing substance A nor B...
Abstract: Blood is the most important body fluid which is responsible for circulation of important nutrients, enzymes and hormones all across the body.The frequencies of ABO and Rhesus blood group system vary geographically, ethnically and from one population to another. Anemia is a global public health problem affecting both developing and developed countries with major consequences for human health as well as social and economic development. During pregnancy,anemia is an important contribu...
Abstract: The ABO and Rh blood groups are the most important blood groups despite the long list of several other blood groups discovered so far. The ABO and Rh blood groups varies worldwide and are not found in equal numbers even among ethnic groups. This study was aimed at getting information and document the frequencies of alleles, phenotypes and genotypes of ABO and Rh (D) blood group systems among Hardim secondary school students. The study was conducted in January 2022 in the laboratory...
Abstract: Blood is the red viscous fluid that circulates around the body supplying O2 and nutritive substances to the tissues and returns CO2 to lungs and metabolites to the kidneys, for regulation of body temperature, and distributes hormones.The frequency of the blood groups varies worldwide and may not be found in equal numbers even among the same ethnic groups.The aim of this study was to find out the distribution of ABO and Rh (D) blood groups,the allele and genotype frequencies among s...
Abstract: White lupin (Lupinus albus L.) is rich in quality protein, relatively tolerant to drought, soil salinity, and acidity, increases the fertility of soils and can contribute to improve white lupin food security and reduce malnutrition which has close associations with climate change. However, it is an underutilized crop in Ethiopia, therefore, as the first step for proper utilization of the crop, this study was conducted to assess the genetic variability of white lupin genotypes for y...
Abstract: Assessment of genetic diversity and variability in crop species is one of the major activities of plant breeding which helps to design breeding methods and/or selection of genotypes for further evaluation to meet the diversified goals including breeding for drought stress conditions. Field experiment was conducted to assess the genetic diversity among bread wheat genotypes, to determine the association among traits, and estimate the direct and indirect effects of traits on grain yi...
Abstract: The purpose of this study was to estimate the extent of genetic variability of agronomic traits and their contribution to seed yield. Twelve quantitative characters genotypes of common bean was studied. The experiment was conducted at karramille farmer’s field as randomized complete block design planted in three replications. Results showed that genotypes with more yields were identified as Tinike for maximum seed yield per plants with values of (120g), Awash-melka for seed per p...
