The evolution of haploidy and diploidy
Tremendous diversity exists among organisms with respect to their ploidy level, defined as the number of sets of homologous chromosomes per cell. As differences in ploidy represent a potentially major genomic change affecting the evolution of a species, it might be thought that ploidy evolution would be well understood. In fact, our knowledge is fragmentary, and there are several open questions...
متن کاملRecombination and the evolution of diploidy.
With two copies of every gene, a diploid organism is able to mask recessive deleterious mutations. In this paper we present the analysis of a two-locus model designed to determine when the masking of deleterious alleles favors the evolution of a dominant diploid phase in organisms that alternate between haploid and diploid phases ("alternation of generations"). It is hypothesized that diploidy ...

15 صفحه اولEnvironmental complexity favors the evolution of learning
Learning is a fundamental biological adaptation that is widespread throughout the animal kingdom. According to previous research, 2 conditions are necessary for learning to be adaptive: between-generation environmental variability and within-generation environmental predictability. In this article, we show that between-generation variability is not necessary and that instrumental learning can p...
