Sex chromosome translocations in the evolution of reproductive isolation.
Haldane's rule states that in organisms with differentiated sex chromosomes, hybrid sterility or inviability is generally expressed more frequently in the heterogametic sex. This observation has been variously explained as due to either genic or chromosomal imbalance. The fixation probabilities and mean times to fixation of sex-chromosome translocations of the type necessary to explain Haldane'...
متن کاملReciprocal translocations in man. 3:1 Meiotic disjunction resulting in 47- or 45-chromosome offspring.
Five cases of chromosome imbalance resulting from 3:1 disjunction of reciprocal translocations are described. A review of the literature suggests this phenomenon is more common than has previously been recognized.
متن کاملMeiosis in two human reciprocal translocations.
Analysis of meiotic chromosomes from two human male translocation heterozygotes is reported. One had total sterility after maturation arrest and chain configurations at meiosis, and the second had a abnormal children who were presumed to be genetically unbalanced.
متن کاملReciprocal translocations in cattle: frequency estimation.
Chromosomal anomalies, like Robertsonian and reciprocal translocations, represent a big problem in cattle breeding as their presence induces, in the carrier subjects, a well-documented fertility reduction. In cattle, reciprocal translocations (RCPs, a chromosome abnormality caused by an exchange of material between non-homologous chromosomes) are considered rare as to date only 19 reciprocal tr...
