A) webbed hands and feet.

D) sickle cell anemia.
E) Down syndrome.

Question

Quizplus · Accepted Answer

Overexpression of Bcl-2 has been associated with the development of certain types of cancer, particularly lymphomas, by allowing abnormal cells to survive and proliferate. In a developing human embryo, overexpression of Bcl-2 could lead to abnormal brain development due to the proliferation of the wrong types of cells. Neither A, D, nor E are related to Bcl-2 overexpression. While abnormal brain development due to too few cells (B) is possible, it is less likely than abnormal development due to too many or the wrong types of cells.
