In contrast, in the testis, spermatocytes initiate meiosis throughout the life of the animal in synchronous waves starting at about a week after birth. Consequently, the signal for initiating meiosis must be regulated differently in males and females. Re ...

TAS2R38 gene has been suggested to influence FP density, as PROP sensitivity has been generally reported as positively correlated with FP density(52–56) and thus tasters of PROP may exhibit higher densities of trigeminal (touch) fibres on the tongue than NT.

... The positioning patterns of γ-H2AX in Jurkat cells indicate that sub-telomeric and actively transcribed regions are sensitive to endogenous DNA damage. Sub-telomeres are known to be prone to replication-mediated DSBs, particularly due to oncogenic replication stress (10,11). DNA hyperreplication in ...

Microevolution

Microevolution is the change in allele frequencies that occur over time within a population. This change is due to four different processes: mutation, selection (natural and artificial), gene flow, and genetic drift. This change happens over a relatively short (in evolutionary terms) amount of time compared to the changes termed 'macroevolution' which is where greater differences in the population occur.Population genetics is the branch of biology that provides the mathematical structure for the study of the process of microevolution. Ecological genetics concerns itself with observing microevolution in the wild. Typically, observable instances of evolution are examples of microevolution; for example, bacterial strains that have antibiotic resistance.Microevolution over time leads to speciation or the appearance of novel structure, sometimes classified as macroevolution. Macro and microevolution describe fundamentally identical processes on different scales.
