Question

Albino rabbits (lacking pigment) are homozygous for the recessive c allele (C allows pigment formation). Rabbits homozygous for the recessive b allele make brown pigment, while those with at least one copy of B make black pigment. True-breeding brown rabbits were crossed to albinos with BB alleles. F1 rabbits which were all black, were crossed to the double recessive (bbcc). The progenies obtained were 34 black, 66 brown and 100 albino.

a. If b and c loci were linked, how many recombinant progenies were there in all progenies.
