Robertsonian heterozygosity in wild mice: fertility and transmission rates in Rb(16.17) translocation heterozygotes.
Breeding data show that there is no distortion of the transmission ratio of chromosomal types in the progeny of wild mice heterozygous for Rb(16.17) nor was litter size significantly affected by chromosomal heterozygosity. The relevance of these results to those obtained with artificial hybrids and to processes of chromosomal differentiation are discussed.
