Answer:

A boy brought a pair home as pets.

Explanation:

As small organisms will not have any major  adaptations for moving quickly or flying to whole another country, hence it is not possible for the snail to travel from Africa to Florida with small animals. Getting stuck on the airplane wing is also not correct as they would have been wiped out by the wind pressure or might have not be able to survive. Hence, the most logical explanation for the snail to get transported to Florida is by a boy who might have brought them as a pet.

In horses, black coat (b) is dominant over brown coat (b), and being a trotter (t) is dominant over being a pacer (t). a black h
Tomtit [17]
In order for a recessive trait to be apparent in an organism, the organism must receive a copy of the allele for that trait from both parents. 
Let the:
black coat: B
brown coat: b
Trotter: T
pacer: t

The offspring received both of the recessive alleles because it demonstrates the recessive phenotypes. Therefore, they genotype of the offspring is:
bbtt

The black horse that is a pacer that can produce this offspring will be:
Bbtt

Therefore, the brown horse's genotype must be:
bbTt

The offspring will receive b from both parents and t from both parents.
