Sex-linked values of E-rosette forming lymphocytes in mother and newborn
The T-cell marker of spontaneous rosettes with sheep erythrocytes was determined in 34 normal term-deliveries on the peripheral lymphocytes of the mother and the corresponding cord-blood lymphocytes of the newborn, immediately after delivery. A consistently lower level of E-rosette forming lymphocytes was observed in male as compared to female newborns in different parity groups and in twin deliveries. When the mean values were calculated for corresponding E-rosettes of maternal and newborn lymphocytes in each group (female and male group of offsprings) they were nearly identical.

Evolution
Around 300 million years ago, the two sex chromosomes diverged from two identical autosomal chromosomes. Over time, the Y chromosome has lost most of its genes, shrinking in size. Today,...
