Abstract

The role played by the nucleus in growth and differentiation of oocytes in lower chordates is well documented (CASPERSSON, 1950; RAO, 1959; MAZIA, 1969). All such studies ask for the determination of changes in the nuclear size at different stages of growth of the oocytes to establish such a role. No account of dimensional changes in a growing oocyte correlated with changes in its nucleus is available for an amniote and to the best of our knowledge, none for a reptile. This communication describes the metrical relationship between growing oocytes and their nuclei in two gekkonine lizards, Hemidactylus flaviviridis and H. brooki, from India with the aim of determining the extent of the influence of the nucleus over the growth and differentiation of the oocytes of these lizards.
