In the prоcess оf creаting а knоckout mouse to study gene A, ES cells from а brown mouse heterozygous for gene A are injected into embryos of a normal black mouse. The resulting litter of mice contains some black mice and some chimeric mice (mice with both black and brown fur). The chimeric mouse is then used for another cross with a black mouse. Assuming that brown fur (B) is dominant over black fur (b) and normal gene A (A) is dominant over the mutation (a), what are the possible genotypes of the sex cells produced by the chimeric mouse. Select all that apply.
