RECESSIVE MUTATION   A recessive mutation is a kind of mutation whereby both alleles must be mutant in order for the mutant phenotype to be observed. This means that the individual must be homozygous for the mutant allele to show the mutant phenotype. on the contrary, the phenotypic expression of a dominant mutation are observed … Read more

Chromosomal Inversion  Chromosomal Inversions are rearrangements of the gene order within a single chromosome, resulting from incorrect repair of two breaks. The amount of chromosomal material remains the same, but recombination within the inverted region leads to unbalanced gametes. Also, due to new order of gene, new nascent protein may be produced. There are different … Read more

Analytical study of cow dung and poultry manure on survival and health performance of plantain genotypes in macropropagation acclimatization process Abstract Macropropagation of plantain is not complete until successful acclimatization of generated plants with environment is achieved. After detaching plantlets from mother corm, high percentage of plantlets is usually lost during acclimatization due to shock … Read more

Evaluation of the Influence of Geographical Location on Phytochemical Composition of Moringa oleifera Seeds Abstract Plants contain phytochemicals that are non-nutritive but have anti-oxidant activity, which protects the body cells from oxidative damage. An example is the seeds of Moringa oleifera which contain phytochemicals of great medicinal importance. Seed samples of Moringa oleifera were collected … Read more

Determination of Shooting Potential and Growth Ability of Plantain Genotypes in Macropropagation Using Saw Dust and Spear Grass (Impereta cylindrica L.) ABSTRACT Plantain (Musa spp.) is one of the most important food crops. To obtain seedlings, most farmers rely on natural regeneration which is a very slow process and do not yield adequate amount. Tissue … Read more

Effect of Cytokinin Concentrations on Shooting ability of plantain Genotypes; ‘Efol’ and Pita 14. ABSTRACT This study was aimed at determining the effect of different6-Benzylaminopurine (BAP) on shooting abilities of two plantain cultivars („Efol‟ and Pita 14). The shoot tips of each genotype were isolated using appropriate protocol for shoot tip isolation under aseptic conditions. … Read more

Comparison of the mineral value of African Yam Bean seeds grown from different Nigerian geographical locations ABSTRACT Nurseries were prepared at different locations in Nigeria which include Abakaliki, Enugu and Ibadan, with seeds of 13 genotypes of African Yam Bean collected from Gene bank of International Institute of Tropical Agriculture, Ibadan. At maturity, they were … Read more
