Relations between organisms and the environment in the ageing process
Przemyslaw Biecek, Katarzyna Bonkowska, Stanislaw Cebrat
We have modified the sexual Penna model by introducing the fluctuating environment and fluctuations representing physiological functions of individuals. Additionally, we have intro…
Why Y chromosome is shorter and women live longer?
Przemyslaw Biecek, Stanislaw Cebrat
We have used the Penna ageing model to analyze how the differences in evolution of sex chromosomes depend on the strategy of reproduction. In panmictic populations, when females (X…
Sexual reproduction from the male (men) point of view
D. Stauffer, S. Cebrat
To counterbalance the views presented here by Suzana Moss de Oliveira, we explain here the truth: How men are oppressed by Mother Nature, who may have made an error inventing us, a…
Scaling effects in the Penna ageing model
A. Laszkiewicz, S. Cebrat, D. Stauffer
We have analysed the possibility of scaling the sexual Penna ageing model. Assuming that the number of genes expressed before the reproduction age grows linearly with the genome si…
Does telomere elongation in cloned organisms lead to a longer lifespan if cancer is considered ?
M. Masa, S. Cebrat, D. Stauffer
... By additionally considering a two-mutation model for carcinogenesis and indefinite proliferation by the activation of telomerase, we demonstrate that the risk of dying doe to c…
Altruism and Antagonistic Pleiotropy in Penna Ageing Model
Stanislaw Cebrat, Dietrich Stauffer
The Penna ageing model is based on mutation accumulation theory. We show that it also allows for self-organization of antagonistic pleiotropy which helps at young age at the expens…
