There are tow hierarchically organized of clonal populations are: genetic individuals (genets) can consist of many physiological individuals (ramets). Each ramet takes up resources from its local environment, but the resource pattern can be reorganized within the clone by transport between ramets. According to obsearvation measurement and surveillance of clones and their ramets of caespitose gr...

The clonal variation in rate of albumin synthesis in hepatoma cells is described as a tool for the study of epigenetic control of differentiation. Previous studies have demonstrated that, from a population of hepatome cells, variant subclones can be readily isolated that produce albumin at different rates. Each clonal variant had a characteristic rate of albumin production, and the clones clust...

BACKGROUND AND OBJECTIVES Clonal hematopoiesis is the hallmark of myelodysplastic syndromes, but the role played by pluripotent stem cells and progenitor cells in these disorders remains unclear. DESIGN AND METHODS Eight female patients with myelodysplastic syndrome were studied. X-chromosome inactivation patterns were analyzed in peripheral blood granulocytes, T-lymphocytes, single colonies ...

We propose an IBM for clonal plant dynamics, focusing on the effects of the network structure of the plants on the reproductive strategy of ramets. After some numerical tests we propose a large population approximation as an advection-diffusion PDE for population densities. 1 The model Individual-based models are in constant development in computational ecology. These models aim to represent th...

The adaptation of large asexual populations is hampered by the competition between independently arising beneficial mutations in different individuals, which is known as clonal interference. In classic work, Fisher and Muller proposed that recombination provides an evolutionary advantage in large populations by alleviating this competition. Based on recent progress in quantifying the speed of a...
