Reduced X-linked nucleotide polymorphism in Drosophila simulans
Reduced X-linked nucleotide polymorphism in Drosophila simulans

... First, the high nucleotide variability of its genome (21) facilitates comparisons of levels of variation from one part of the genome to another. Second, although there are fewer genetic data for D. simulans than for D. melanogaster, the available D. simulans data indicate that there is relatively li ...

... majority of phenotypes are “polygenic”, meaning they are influenced by multiple genes (Mackay 2001, Plomin 2008), and are shaped by a multitude of environmental forces. As a result, simple association models between genotype and phenotype are an important first step to establish candidate genes, but ...

According to their hypothesis, the ribosomal duplicates have subfunctionalized at the expression level due to mutations in the regulatory non-coding regions. Nevertheless, there is still v ...

These new data sets should contain phylogenetic signal similar to that in the original data. A high percentage of replicates (75%+ ...

Yet, an ordered and timed activation of genes and their associated molecular pathways are central for the growth and development of healthy bones. The correct expression of genes depends on both cis- and trans-regulatory el ...

... Historically, metazoan animals were subdivided into diploblasts and triploblasts. Diploblasts have two germ layers, the endoderm and the ectoderm, while the triploblasts have a well-defined third germ layer, the mesoderm. This division is based upon the so-called germ layer concept, which has been a ...

... avian W; in contrast to this, sex chromosomes in fish, if present at all, are often homomorphic and differentiation is not detectable by karyotyping [2]. Overall, fish show frequent turnover of sex-determining systems [5], which stands in sharp contrast to other vertebrate clades, especially to bird ...

The pentaploid hybrid between L. multiflorum (Lm) (2n = 4x = 28)ÅF. arundinacea (Fa) (2n = 6x = 42) used for anther culture was produced as described by Humphreys (1989), and has a genomic constitution of LmLmFpFgFg1 (Fp = F. pratensis, FgFg1 = F. glaucescens). The two homologous chromosomes of Lm a ...

Minimal genome

The concept of minimal genome assumes that genomes can be reduced to a bare minimum, given that they contain many non-essential genes of limited or situational importance to the organism. Therefore, if a collection of all the essential genes were put together, a minimum genome could be created artificially in a stable environment. By adding more genes, the creation of an organism of desired properties is possible. The concept of minimal genome arose from the observations that many genes do not appear to be necessary for survival. In order to create a new organism a scientist must determine the minimal set of genes required for metabolism and replication. This can be achieved by experimental and computational analysis of the biochemical pathways needed to carry out basic metabolism and reproduction. A good model for a minimal genome is Mycoplasma genitalium, the organism with the smallest known genome. Most genes that are used by this organism are usually considered essential for survival; based on this concept a minimal set of 256 genes has been proposed.
