Respuesta :
Finches have grown apart genetically due to isolation, resulting in minimal cross breeding. This means that each finch population developed into its own species; therefore, breeding is minimal. Moreover, the offspring from these crosses are likely to have genetic diseases due to the mixed genes.
Since finches breed in isolated areas, hybrid species are rare.
A hybrid is an organism that displays the characteristics of two different populations. We must note that finches are known to breed in isolated areas. As such, hybrid species are rare.
Where hybrid species do occur, it is common to observe disease conditions making the finches not to be as fit as either parent species.
