Genetic Diversity and Population Structure of Busseola segeta Bowden (Lepidoptera; Noctuidae): A case study of host use diversification in Guineo-Congolian rainforest relic area, Kenya
(School of Biological Sciences, 2012)Abstract: Habitat modification and fragmentation are considered as some of the factors that drive organism distribution and host use diversification. Indigenous African stem borer pests are thought to have diversified their ... -
Genetic diversity of the African wild rice (Oryza longistaminata Chev. et Roehr) from Ethiopia as revealed by SSR markers
(2013)Data from microsatellite markers have been extensively used for both in situ and ex situ conservation strategies by determining the level of genetic diversity of natural populations that can widen the gene pool of cultivated ... -
The genetic identify of Ceratopogon imperfectus (Culicoides imperfectus Geot)
(University of Nairobi,School of Biological Sciences, 1973) -
Genetic relatedness among Fusarium species isolated from Taita Taveta Region, Kenya
(2009)Unweighted Pair Group Method with Arthmetic mean (UPGMA) cluster analysis using computer package NTSYS-pc. Jaccard’s similarity coefficients ranged from 0.257 to 0.583 among the Fusarium species studied indicating high ... -
A genetic sexing strain of Anopheles albimnus
(University of NairobiCollege of biological and physical science, 1983) -
Genetic similarity among Cercospora apii-group species detected by PCR/RFLP analyses of the rDNA internal transcribed spacer (ITS).
(University of NairobiCollege of biological and physical science, 2000) -
Genetic structuring in the spotted gum complex (genus Corymbia, section Politaria)
(University of NairobiCollege of biological and physical science, 2008) -
Genetic variation in the predacious mite, Amblyseius swirskii ( Acari: Phytoseiidae): Analysis of specific mitochondrial and nuclear sequences.
(University of NairobiSchool of Biological and Physical Sciences, 2004)Patterns of polymorphism of two DNA fragments with contrasted modes of evolution, mitochondrial DNA (mtDNA) and nuclear ribosomal DNA (rDNA), were used to study population structure and taxonomy of the predacious mite, ... -
Genetic variation in wild Anopheles arabiensis Patton of Mwea Irrigation Scheme, Kenya
(Cambridge University PressDepartment of Botany, University of Nairobi, 1987)Electrophoretic variation was determined at eight enzyme loci in Anopheles arabiensis from four villages in Mwea Irrigation Scheme, Kenya. Seven loci had polymorphic alíeles of which at least two were common. Pooled allele ... -
Genetic variation in wild Mediterranean fruit fly, Ceratitis capitata (Wied), from Kenya
(University of NairobiDepartment of Botany, University of Nairobi, 1990) -
Genetic Variations and their Association with Diseases among Kenyan Ethnic Populations
(University of Nairobi, 2010)Human populations are polymorphic for many loci. The inhabitants of different regions of the earth can be characterised on the basis of the relative gene frequencies. These gene frequencies have been associated with certain ... -
Genetically Modified Organisms

Genetics of the mimetic African butterfly Hypolimnas misippus: hindwing polymorphism
(University of Nairobi,, 1989)The hindwing polymorphism in Hypolimnas misippus is autosomal but sex-limited to the female. It is characterised by three intergrading phenotypes, orange, low white (white in 1–3 intervein spaces) and high white (white in ... -
Genetics: The science of life
(University of NairobiCollege of biological and physical science, 1980) -
The genomes of three stocks comprising the most widely utilized live sporozoite Theileria parva vaccine exhibit very different degrees and patterns of sequence divergence.
(2015-09)There are no commercially available vaccines against human protozoan parasitic diseases, despite the success of vaccination-induced long-term protection against infectious diseases. East Coast fever, caused by the protist ... -
Genomic and Pathogenic Characteristics of Virulent Newcastle Disease Virus Isolated from Chicken in Live Bird Markets and Backyard Flocks in Kenya
(University of Nairobi, 2020)Newcastle disease (ND) causes significant economic losses in the poultry industry in developing countries. In Kenya, despite rampant annual ND outbreaks, implementation of control strategies is hampered by a lack of adequate ... -
Genomic Polymorphism, Sexual Recombination and Molecular Epidemiology of Theileria Parva
(University of Nairobi, 2003)Over the past decade there has been an exponential increase in studies of parasites using molecular techniques. These techniques have been applied to increase our understanding of the interface between pathogen genome ... -
Genomic selection using regularized linear regression models: ridge regression, lasso, elastic net and their extensions.
(University of NairobiSchool of Computing and Informatics, 2012)BACKGROUND: Genomic selection (GS) is emerging as an efficient and cost-effective method for estimating breeding values using molecular markers distributed over the entire genome. In essence, it involves estimating the ... -
Genotypic variations in field isolates of Theileria species infecting giraffes (Giraffa camelopardalis tippelskirchi and Giraffa camelopardalis reticulata) in Kenya
(University of NairobiDepartment of Biochemistry, 2013-10)Recently, mortalities among giraffes, attributed to infection with unique species of piroplasms were reported in South Africa. Although haemoparasites are known to occur in giraffes of Kenya, the prevalence, genetic diversity ...
