The hitch-hiking effect of a favourable gene.
When a selectively favourable gene substitution occurs in a population, changes in gene frequencies will occur at closely linked loci. In the case of a neutral polymorphism, average heterozygosity will be reduced to an extent which varies with distance from the substituted locus. The aggregate eifect of substitution on neutral polymorphism is estimated; in populations of total size 10 or more (...
متن کاملGenetic hitch-hiking in a subdivided population.
The problem of genetic hitch-hiking in a geographically subdivided population is analysed under the assumption that migration rates among populations are relatively small compared with the selection coefficient for a newly arising advantageous allele. The approximate method used in the paper is valid when the number of emigrants per generation (Nm) is less than one. The approximate analysis sho...
متن کاملTc7, a Tc1-hitch hiking transposon in Caenorhabditis elegans.
We have found a novel transposon in the genome of Caenorhabditis elegans. Tc7 is a 921 bp element, made up of two 345 bp inverted repeats separated by a unique, internal sequence. Tc7 does not contain an open reading frame. The outer 38 bp of the inverted repeat show 36 matches with the outer 38 bp of Tc1. This region of Tc1 contains the Tc1-transposase binding site. Furthermore, Tc7 is flanked...
متن کاملThe effect of hitch-hiking on genes linked to a balanced polymorphism in a subdivided population.
The effect of multi-allelic balancing selection on nucleotide diversity at linked neutral sites was investigated by simulations of subdivided populations. The motivation is to understand the behaviour of self-recognition systems such as the MHC and plant self-incompatibility. For neutral sites, two types of subdivision are present: (1) into demes (connected by migration), and (2) into classes d...
متن کاملLow Power Hitch-hiking Broadcast in Ad Hoc Wireless Networks
Energy consumption is an important factor to be considered in designing algorithms for ad hoc wireless networks, where wireless nodes are assumed in general to be battery powered. The Hitch-hiking model introduced recently in [1] takes advantage of the physical layer design that facilitates combining of partial signals containing the same information in order to decode the complete message. Aga...
