Inheritance and linkage data for an unusual combination of genes (at the LKE, PI and C6 loci) in a single large sibship.

abstract：:The index of opportunity for selection proposed by Crow has been calculated for the Italian population during the last century. The evolution of its two components, the pre-reproductive mortality and the variance in fertility, has been also analysed and compared with similar data for the United States. The results cle...
