in the mid-1800’s one man began a genetic study of pea plant that is still the foundation for genetics today. he worked with a quick growing, easy to obtain plant that allowed him to experiment with the inheritance of a single trait, like flower color. his experiments lead to such genetic foundations as the law of dominance and the principle of segregation.

this early geneticist is
a) darwin.
b) mendel.
c) morgan.
d) watson.

explanation:

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
