How to get the find the phenotypic ratio and Genotypic ratio for this?

Dear Student,

Parents                         AaBbCc   (Mother)      x       aaBbcc (Father)

No of Gametes                       2³ (8)                               2¹ (2)
Gametes                ABC, ABc, AbC, Abc,                       aBc and abc 
                              aBC, aBc, abC, abc    

Number of gametes = 2ⁿ  (number of heterozygous pairs) 

F1 will be 

	aBc	abc
ABC	AaBBCc	AaBbCc
ABc	AaBBcc	AaBbcc
AbC	AaBbCc	AabbCc
Abc	Aabbcc	Aabbcc
aBC	aaBBCc	aaBbCc
aBc	aaBBcc	aaBbcc
abC	aaBbCc	aabbCc
abc	aaBbcc	aabbcc

Now, it is given AaBbCc - Dark 
aaBbcc - Almost White
AaBBCc - More Dark
aabbcc - White.

Using the above cross and given phenotypes rest can also be easily computed.
