Genotypic and phenotypic classes

If these three genes were all assorting independently, how many genotypic and phenotypic classes would result in the offspring, and in what proportion, assuming simple dominance and recessiveness in each gene pair?

	8, 1:1:1:1:1:1:1:1
	2, 1:1
	6, 1:1:1:1:1:1
	4, 1:1:1:1

What can you conclude from the actual data about the location of the three genes in relation to one another?

The B and C loci are linked and locus A assorts independently from both B and C loci.
	The A and B loci are linked and locus C assorts independently from both A and B loci.

How far apart are the linked genes?

	5 map units
	10 map units
	15 map units
	20 map units
	40 map units

20	AaBbCc	20	AaBbcc
20	aabbCc	20	aabbcc
5	AabbCc	5	Aabbcc
5	aaBbCc	5	aaBbcc
