Final answer:
The most likely abnormality to be seen in erythrocytes in lead poisoning is basophilic stippling, which refers to the presence of small, dark granules in the cells.
Step-by-step explanation:
Erythrocytes, or red blood cells, are responsible for carrying oxygen throughout the body. In lead poisoning, the most likely abnormality to be seen in erythrocytes is basophilic stippling, which refers to the presence of small, dark granules in the cells. These granules are aggregates of ribosomes and are indicative of lead poisoning. Other options such as Howell-Jolly bodies (found in individuals with spleen disorders), Heinz bodies (found in individuals with G6PD deficiency), and target cells (found in individuals with liver disease) are not typically associated with lead poisoning.
