Genetic linkage and molecular evolution
The rate of genetic recombination varies among species, and across different regions of the genome within a species. In the extreme case, all genes in an asexual or selffertilizing species are effectively completely linked, in contrast to the substantial opportunities for recombination in outbreeding sexual species. Several key observations on the relation between patterns of evolution and leve...
متن کاملGenetic recombination and molecular evolution.
Reduced rates of genetic recombination are often associated with reduced genetic variability and levels of adaptation. Several different evolutionary processes, collectively known as Hill-Robertson (HR) effects, have been proposed as causes of these correlates of recombination. Here, we use DNA sequence polymorphism and divergence data from the noncrossing over dot chromosome of Drosophila to d...
متن کاملThe evolution of evolvability in genetic linkage patterns.
A number of factors have been proposed that may affect the capacity for an evolutionary system to generate adaptation. One that has received little recent attention among biologists is linkage patterns, or the ordering of genes on chromosomes. In this study, a simple model of genetic interactions, implemented in an evolutionary simulation, demonstrates that clustering of epistatically interacti...
متن کاملMolecular genetic linkage maps for allotetraploid Leymus wildryes (Gramineae: Triticeae).
Molecular genetic maps were constructed for two full-sib populations, TTC1 and TTC2, derived from two Leymus triticoides x Leymus cinereus hybrids and one common Leymus triticoides tester. Informative DNA markers were detected using 21 EcoRI-MseI and 17 PstI-MseI AFLP primer combinations, 36 anchored SSR or STS primer pairs, and 9 anchored RFLP probes. The 164-sib TTC1 map includes 1069 AFLP ma...
متن کاملBipolar Disorders: Review of Molecular Genetic Linkage Studies
This chapter reviews evidence of the heritability of bipolar (BP) and recurrent unipolar (RUP) disorders. This evidence has accumulated through family, twin, adoption, linkage, and candidate gene studies. Both the twin and family studies suggest that unipolar and bipolar disorders share some fraction of genetic susceptibility. Data from the twin and family studies can be used for genetic counse...
