Depending on sex and age, the number of units of AgNORs in the nuclei of the erythrocytes of ducks at the
first year of life is from 5 to 12. The average area of AgNORs in the nuclei of erythrocytes is in the range from
0.330 ± 0.008 to 0.564 ± 0.009 µm2. The data obtained attest to the fact that there are age and sex differences
in the dynamics of changes in the number and area of AgNORs in the nuclei of the erythrocytes of ducks. Males
of ducks number of AgNORs in the nuclei of erythrocytes in waves from birth until the age of 12 months age,
with periods of increasing alternating with periods of decline. In females ducks, undulating nature of the change
can be traced up to 6 months of life and then the number of AgNORs is maintained at a high level in subsequent
age periods.
