DEPRESSION AND ANXIETY; HIDDEN DEADLY DISEASES INTRODUCTION Nobody wants to be associated with failure. The struggles for success have lured people to their early graves. Yes, it is commendable to have anticipated results and record applaudable successes. But, due to challenges that abound, some goals are unattained. People react differently to failures. While some people …
SCREENING FOR SEED FERTILITY THROUGH PLOIDY MANIPULATION AND INTER-SPECIFIC HYBRIDIZATION AMONG Musa ACCESSIONS. ABSTRACT This work was aimed at assessing the variability of male and female fertility to enhance yield, quality and physiology in Musa breeding program. Musa germplasm at Ebonyi State University Abakaliki were characterized using morphological descriptors, SCoT markers and the count …
CHARACTERIZATION OF EBONYI STATE UNIVERSITY ABAKALIKI Musa GERMPLASM USING FOUR POLYMORPHIC MARKERS ABSTRACT Musa spp (plantain and banana) are important starchy staples in Nigeria in particular. They are of great socioeconomic importance, but their production has been saddled by several constraints which include pests, diseases, and lack of improved cultivars. In an attempt to overcome …
CROP IMPROVEMENT: IMPORTANT MEANS FOR NATIONAL FOOD SECURITY AND GROWTH ABSTRACT The demand for food continues to rise across Nigeria as population increases. Nigeria has about 79 million hectares of arable land, of which only 32 million hectares are cultivated. However inadequate access and a low supply of high-quality crops have contributed heavily to a …

EXTENDED SPECTRUM BETA-LACTAMASE (ESBL) SCREENING OF Klebsiella spp FROM POULTRY, MARKET AND HOUSEHOLD ENVIRONMENT IN ABAKALIKI BACKGROUND STUDY Extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae are increasing in prevalence worldwide, it varies according to geographic locations and is directly linked to the use and misuse of antibiotics (Canton et al., 2008). ESBLs confer resistance to most beta-lactam antibiotics, including 1st, …
CHROMOSOME: The house of genes INTRODUCTION Living things are made up of cells as their building blocks, within the cell are different organelles, among which is the nucleus (plural: nuclei). Inside the nucleus, the deoxyribonucleic acid (DNA) is wound tightly and packaged into a compact unit called a chromosome. So, each chromosome is comprised of …
CELL DIVISION INTRODUCTION The growth that organisms experience is a corollary of cell division, although, it is not every cell division that leads to growth in organisms. An example is seen in eukaryotic organisms where mitotic cell division increases the number of cells of the organism. This cell number increment leads to growth and also …

MENDEL’S WORK: THE EYE OPENER TO GENETICAL STUDY INTRODUCTION In a couple of decades, before Gregor Mendel was born in 1822, experimental hybridization was achieved and documented in 1760 by a researcher called Josef Kölreuter. Joseph Kölreuter crossed different strains of tobacco and generated fertile offspring which varied in appearance from the strain of the …

BREEDINGÂ INTRODUCTION Every average farmer is concerned with how to maintain food supply despite any sharp increase or decrease in population, constant reduction in agricultural land, and unfavourable environmental conditions that may emerge intermittently. It is with this concern that plant breeding was introduced. Plant breeding is the art and science of altering the genetic …
HYBRIDIZATION 1. INTRODUCTION Every day, the need to incorporate different traits in one organism increases. This is because there is hardly one organism that has all the desired traits. This calls for a high need for researchers to improve on deciphering a means of having desirable traits in one organism. Among many techniques, hybridization has …
