Genetic linkage mapping of allozyme loci in even- and odd-year pink salmon (Oncorhynchus gorbuscha).
We constructed genetic linkage maps of allozyme loci in even- and odd-year pink salmon (Oncorhynchus gorbuscha), using the total of 320 families (each female was crossed with two different males, and 80 females and 160 males were used for each of even year and odd year). The maps include eight linkage groups involving 22 loci. We observed substantial variation in recombination frequencies among...
متن کاملIntra - chromosomal association between allozyme loci in Drosophila ananassae
Non-random association between gene arrangements was referred to as linkage disequilibrium by Lewontin and Kojima (1960) and according to them this happens due to linkage between such arrangements. Chromosomal polymorphism in association with allozymes has been extensively studied in Drosophila (Rodriguez-Trelles, 2003; Iriarte et al., 2002; Rodriguez et al., 2000; Kamping and Delden, 1999; Zap...

متن کاملFixation, segregation and linkage of allozyme loci in inbred families of the Pacific oyster Crassostrea gigas (Thunberg): implications for the causes of inbreeding depression.
The effect that inbreeding has on the fixation and segregation of genes has rarely been confirmed by direct observation. Here, fixation, segregation, and linkage of allozymes is investigated in the progeny of self-fertilized hermaphrodites of the normally outcrossing Pacific oyster Crassostrea gigas. The estimate of fixation pooled over loci, individuals, and families, F = 0.462, is significant...
متن کاملLinkage arrangement of human placental lactogen and growth hormone genes.
Human placental lactogen (hPL) and growth hormone (hGH) are two hormones thought to have evolved from a common ancestral gene (along with prolactin), yet they have quite different functions and specificities. The nucleic acid sequences of the respective cDNAs of the two genes share considerable homology, as well as the existence of multiple forms of each gene within the genome. In this study we...
