OK, assuming that these are your true, white charolais.
A. Homo black would give you various shades of grey. Anywhere from almost white to almost black.
B. Hetero black would give you various shades of grey AND various shades of tan.
C. Gelbveih would depend on what color. Homo black, same as above, hetero black same as above. Red would give you various shades of tan.
D. Black Angus would be the same as A or B, depending on whenther the bull was homo or hetero.
E. Maine would give you tan calves. Some might be spotted as well, because Char can carry the recessive spotting gene.
The dilutor gene (that the Char carries) is a dominant gene. What this means is that if the animal carries the gene it will be visible. A homo dilute animal will be white, a hetero dilute animal would be either gray (black base coat) or tan (red base coat). Charolais are genetically RED and Homo Dilute.
