Only viability fitnesses are considered. The FTNS also assumes in effect an infinitely lar ...

... Because of this limitation, we began our assay development efforts using a large initial set of 166 loci (figure 1). This set was chosen because they were likely to be expressed in our samples (i.e. in blood) and because they scored highly on a predictive algorithm for common ASGE [53]. We also adde ...

However, the vast majority of mitochondrial proteins are now encoded in nuclear DNA. These genes are transcribed in the nucleus, translated on cytosolic ribosomes and directe ...

... Remarks. (a) The above ”halves” have nothing to do with the two strands of DNA but rather with diploidy of certain organisms, e.g. human and pea plants, who have two sets of chromosomes inherited from the two parents. (b) There is a relatively small group of genes, namely the genes positioned on the ...

Since a hallmark of SAR is its dependence upon SA accumulation [15••], testing the function of a pathway in the presence of the SA-catabolizing enzyme salicylate hydroxylase can be informative. For example, the cpr5 mutant of Ara ...

... Population genetics deals with analysis of gene frequencies in a population over many generations. The concept of describing frequencies of inherited traits owes its origin to scientific works published at the beginning of the 20th century. A 1908 paper, “Mendelian Proportions in a Mixed Population” ...

... In animals, oocyte development arrests at the first meiotic prophase. Oocyte maturation then resumes in response to specific triggers, which, in C. elegans, take the form of the major sperm protein (MSP, an ephrin signalling antagonist). Now, two studies by David Greenstein and co-workers shed light ...
