Secondary tetrasomic segregation of MDH-B and preferential pairing of homeologues in rainbow trout.

Genetics - 1 Apr 1997

Allendorf F W, Danzmann R G

Abstract excerpt

We examined the inheritance of allelic variation at an isozyme locus, MDH-B, duplicated by ancestral polyploidy in salmonid fishes. We detected only disomic segregation in females. Segregation ratios in males were best explained by a mixture of disomic and tetrasomic inheritance. We propose a two-stage model of pairing in male meiosis in which, first, homologous chromosomes pair and recombine in the proximal...
