A student is doing a genetics experiment on beetles. A pure green beetle is crossed with a pure brown beetle. The student repeats this experiment ten more times. Every time the student performs this cross, all of the offspring is green. If two offspring of the pure green beetle and pure brown beetle were crossed, what is the probability that their offspring would be green colored?

thats not a question

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.

d. changes in climate and historical records

hope this
