It depends on the particular ecosystem and why and how it was destroyed. It can take just 2 years or over 100 years depending on the different factors. Sometimes ecosystems never recover.
Answer:
Because A is co-dominant to B and O is recessive, so the genotype is the same as the phenotype. But A can have 2 genotypes because A can mask a recessive allele, which makes the phenotype A. B can also mask a recessive allele, which makes the phenotype B.
Examples
AO (genotype) = A (phenotype)
BO (genotype) = B (phenotype)
