A decrease in the proportion of large beaked birds in the population the next generation

An increase in the proportion of large beaked birds in the population the next generation&nbsp;

An increase in the proportion of small beaked birds in the population the next generation

Both species will remain approximately in equal frequency

Geospiza fortis lives on the Galapagos islands along with fourteen other finch species. It feeds on the seeds of the plant  tribulus cistoides, specializing on the smaller seeds. Another species, G. magnirostris, has a larger beak and specializes on  the larger seeds. The health of these bird populations depends on seed production. Seed production, in turn, depends on  the arrival of wet season. In 1977, there was a drought. Rainfall was well below normal and fewer seeds were produced. As  the season progressed, the G. fortis population depleted the supply of small seeds. Eventually, only larger seeds  remained. Most of the finches starved; the population plummeted from about twelve hundred birds to less than two  hundred Under the given scenario which would be the probable outcome?
