This study evaluates the growth performance, body linear parameters and egg quality of Yoruba ecotype chicken their F1 F2 crosses using Lohmann brown cocks under a low-input management system. Ten were mated with thirty indigenous hens to obtain progenies. also back Also, ten male 30 female as basis for comparison. Mating was done at 1:3 in all groups. Incubation hatching naturally properly mon...

Natural selection acts strongly on the proportional numbers of male and female offspring among the progeny of adults. The equilibrium is often one at which males and females are produced in roughly equal numbers, but under certain ecological and genetic circumstances there may be dramatic population-wide biases, and even in populations with balanced sex ratios, parents are often selected to pro...

Chloroplast DNA (cpDNA) inheritance was investigated in Sorbus aucuparia using progenies obtained from six controlled crosses between individuals of known haplotype. Polymerase chain reaction (PCR) amplification, followed by restriction analysis, was used to characterize 248 offspring for either of two polymorphic cpDNA fragments. All offspring exhibited the maternal haplotype, which indicates ...

The metabolic changes of human mesenchymal stem cells (hMSCs) during osteogenic differentiation were accessed by reduced nicotinamide adenine dinucleotide (NADH) fluorescence lifetime. An increase in mean fluorescence lifetime and decrease in the ratio between free NADH and protein-bound NADH correlated with our previously reported increase in the adenosine triphosphate (ATP) level of hMSCs dur...

This study investigated oil palm inflorescence sex ratio (ISR) and fruit set (FS) yield among 24 dura × pisifera biparental progenies on fibric peat soil, hybridized from ten genetic origins. Three-month intervals of data collection ISR “S-shape” procedure for FS determination were carried out in an independent complete randomized design one year. Based the assessment individual progenies, anal...
