I would say that the fishes exhibited the greatest diversity (though the brachiopods also had considerable diversity) and mostly were of the ostracoderms (with a platey or shell-like skin and no jawbone) which exhibited many varieties and also the placoderm which had gills, a jawbone and fins so was developing characteristics of modern fish.

BB BB

Bb Bb

The percentage will be as follows:

- You will have 50% heterozygous (Bb)

Now, for the phenotype, you will have 100% black fur, since B is dominant and is prevalent in 100% of all the breeds.

For the genotype, you have 50% BB and 50% Bb
