  • 39, no. of balanced offspring that inherit the Robertsonian translocation. 40, no. of balanced offspring with the normal karyotype. n, number of samples analyzed. χ2, chi square under the expectation of the null hypothesis of random segregation. Numbers underlined represent significant departures from the expectations. References: 1, Evans et al. (1967); 2, Gropp and Winking (1981); 3, Boue et al. (1985); 4, Harris et al.
