Answer:
Genetic testing was carried out on 5110 and the grants concluded that he was a hybrid. He has G. fortis and G. scandens genes.
See below further explanation
Step-by-step explanation:
When 5110 first appeared, the Grants did not know how to classify him.
Where did he come from? Was he a new species of finch, or was he an infertile hybrid of known species? If birds prefer to mate with other birds from their own species, what would 5110's fate be on Daphne where there were no other birds
Genetic testing was carried out on 5110 and the grants concluded that he was a hybrid. He has G. fortis and G. scandens genes.
He was probably from a G fortis parent and hybrid G scandens .
crossbreeding is when The same species of different features/genetic make up are made to mate with the same of different features/genetic makeup and the product can have an enhanced quality
5110 will be a big bird, if there is an interbreeding between the hybrid G Scandens and G. fortis
