A scientist crossed a tall pea plant with a short pea plant . Of the offspring 13were tall 12 were short . Write the raito of the phenotype to the total number of offspring. Express the ratios as fractions. I

B.
Use the fractions to calculate the percentage of the offspring that were tall and the percentage that were short

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.
