Answer:
The genotype of the parents are not given. Let's try to answer this question generally. Let's assume the genotype of both parents to be Bb as genotype is not given.
Explanation:
B b
B BB Bb
b Bb bb
There is a 25% chance that the offspring will have BB genotype.
There is a 50% chance that the offspring will have Bb genotype.
There is a 25% chance that the offspring will have bb genotype.
There is a 75% chance that the offspring will have a dominant trait.
There is a 25% chance that the offspring will have recessive trait.
Phenotypic ratio will be 3:1

Answer:
The correct option is A) will make no difference in the survival of life if there were major changes in the environment.
Explanation:
Due to genetic diversity, variations in species are caused which makes some organisms of a species to be better adapted than other members of the species. These variations cause organisms to survive when differences in the environment occur. Although the allele frequencies might change due to the changes in the environment but the phenomenon of genetic diversity allows life to sustain on earth even when conditions will become unfavourable.

Answer:
The Geographic barrier would have led to speciation in the finches which started from the founder effect where the finches were brought to other areas of the Galapagos. They were separated geographically so they could not mate with each other. Over time, evolution occurs through natural selection and genetic drift. This leads to the population being so different so they have reproductive barriers and can no longer interbreed. They become different species.
