Look at the Chromosomes Above and Determine How Many Group(s)

Look at the chromosomes above and determine how many group(s) of Hox genes are associated with body types for each type of animal. These associations are based on anterior, group 3, central and posterior body development.

A) Mammals: 4 groups; Flatworms: 4 groups; Sponge: 2 groups; Anemones: 1 group.
B) Mammals: 4 groups; Flatworms: 4 groups; Sponge: 1 groups; Anemones: 2 group.
C) Mammals: 11 groups; Flatworms: 4 groups; Sponge: 1 groups; Anemones: 4 groups.
D) Mammals: 27 groups; Flatworms: 4 groups; Sponge: 2 groups; Anemones: 1 group.
E) All animals must have at least 2 groups because all animals have a posterior and anterior end.
