We present a computational model to reconstruct ancestor trees of animals with sexual reproduction following the theoretical model presented in Phys. Rev. E 90, 022125 (2014). Through a recursive algorithm combined with a random number generator, it is possible to reproduce the number of ancestor for each generation and use it to constraint a maximum number of the following generation. This sim...

The classical, ubiquitous, predecessor problem is to construct a data structure for a set of integers that supports fast predecessor queries. Its generalization to weighted trees, a.k.a. the weighted ancestor problem, has been extensively explored and successfully reduced to the predecessor problem. It is known that any solution for both problems with an input set from a polynomially bounded un...

Identity-by-descent probabilities are important for many applications in genetics. Here we propose a method for modeling the transmission of the haplotypes from the closest genotyped relatives along an entire chromosome. The method relies on a hidden Markov model where hidden states correspond to the set of all possible origins of a haplotype within a given pedigree. Initial state probabilities...

There are two types of photosynthesis, C3 and C4, and computational techniques have been used to explore how C4 plants evolved from their C3 ancestors.

Development of ozone (O3)-resistant cultivars is a potentially important approach for maintaining crop productivity under future climate scenarios inwhich tropospheric O3 pollution is projected to rise. A first step in the breeding of resistant cultivars for a crop such as soybean (Glycine max (L.) Merr.) is identification of sources of O3 resistance genes. Thirty ancestral lines of soybean wer...

Asexual reproduction is expected to reduce the adaptive potential to novel or changing environmental conditions, restricting or altering the ecological niche of asexual lineages. Asexual lineages of plants and animals are typically polyploid, an attribute that may influence their genetic variation, plasticity, adaptive potential, and niche breadth. The genus Boechera (Brassicaceae) represents a...

As a means of opening the lid on transgenerational silencing—which was survival strategy for thousands Indigenous families against intended cultural genocide—while balancing place auto/biography in that journey, this paper focuses impact Ancestors’ hidden histories and how discovery those drives complex identifications when woven with Presences, places, people Dharug Ngurra/Country. Using my ow...

Over the millennia various hominoids and hominids have subsisted on very different dietaries, depending on climate, hunting proficiency, food-processing technology, and available foods. The Australopithecines were not browsers and fruit-eaters with very high intakes of vitamin C; rather they were scavengers of kills made by other animals. The hominids who followed did include some cold-climate ...
