You make the following observations:
a) A cross between a purebred lime green Tribble and a purebred red Tribble produces offspring that are all red.
b) A cross between a long-haired Tribble and a short haired Tribble produces fuzzy, (medium length hair), offspring.
c) Occasionally an unusual plaid coated Tribble is born. The plaid offspring are almost always male, and in most cases, neither parent is plaid. A plaid male rarely has a plaid male son, but the father must be plaid for the female offspring to be plaid.
d) Tribbles with whiskers can have long whiskers, short whiskers, a mix of long and short whiskers or no whiskers at all.
From the list above determine which trait represents (you will use one letter more than once) -
A dominant(expressed)/recessive(not-expressed) pattern,
d co-dominance(expression) pattern
B incomplete dominance (expression) pattern
multiple alleles
