ild-type mouse that is heterozygous for two immunoglobulin heavy chain alleles (IgHa/b) generates the population of B cells shown on the left of the figure below.  A mouse strain, also IgHa/b, carries an inactivating mutation in the VpreB gene. In addition to producing fewer mature B cells than the wild-type mice, the VpreB-deficient mice generate B cells as shown on the right.  What is the explanation of the difference seen between the wild-type and the VpreB-mutant B cells?

A wild-type mouse that is heterozygous for two immunoglobulin heavy chain alleles (IgHa/b) generates the population of B cells shown on the left of the figure below.  A mouse strain, also IgHa/b, carries an inactivating mutation in the VpreB gene. In addition to producing fewer mature B cells than the wild-type mice, the VpreB-deficient mice generate B cells as shown on the right.  What is the explanation of the difference seen between the wild-type and the VpreB-mutant B cells?
