Here there is an excess of pink-eye. 

 Pink-eyed yellow x pink-eyed yellow heterozygous in black and chocolate : 



Here there is an excess of chocolate-lilac possibly due to the fact 

 that some of the yellows were heterozygous in blue lilac only and 

 others in chocolate only, and those mated together would give chocolate 

 lilacs only, no blues and no champagnes.
