Abstract:
<strong>Background: </strong>Giant African land snail (<em>Archachatina marginata</em>) is a micro livestock with potentials as a protein source especially among impoverished individuals. As such, it requires much research attention to fully unveil it genetic nature for possible improvements. <strong>Materials and Methods: </strong>Two hundred (200) snails consisting of one hundred (100) each of black-skinned ectotype and white-skinned ectotype were selected based on number of whorls from a population gathered in the wild within Cross River State for the study. Data collected on number of whor

Abstract:
The study investigated the reproductive potentials of two edible ectotype of giant land snails <em>(Archachatina marginata ovum and Archachatina marginata Saturalis</em>) fed banana leaves in the humid tropical zone of Cross River State within a 16 week period. The reproductive potentials of the two ectotypes of giant lands snail revealed that <em>Archachatina marginata ovum </em>performed better (P &lt;0.05) than <em>Archachatina marginata Saturalis</em> in terms of total number of eggs lard, clutch size, incubation period, egg weight, egg length and egg width. However, no differences (P&gt;0

Abstract:
This study evaluated the type of mutation associated with SNPs of black skinned and white skinned snails (Archachatina marginata) in the rainforest zone of Nigeria. Fourty eight (48) Archachatina marginata snails were assigned to two treatments using completely randomized design. The two treatments consisted of twenty four (24) white skinned ecotypes and twenty four(24) black skinned ecotypes with 12 replicates each. These snails were taken to laboratory to conduct DNA analysis to evaluate the mutation type that is associated with the SNPs of the two snail ectotypes. The quality of DNA was ass

Abstract:
White skinned ectotypes were used in a study to estimate heterosis, correlation and regression. Data collected on the snails and their eggs included body weight (BWT), shell length (SLH), shell width (SWH), “mouth” length (MLH) and “mouth” width (MWH); and egg weight (EWT), egg length (ELH) and egg width (EWH), respectively. These data were used to estimate correlations between pairs of traits, heterosis and to predict weight from other morphometric traits among three mating groups [black skinned x black skinned (BAM X BAM), white skinned x white skinned (WAM X WAM) and their cross BAM X WAM)]
