While volunteering at texas children's hospital, you are asked to tabulate the occurance?
of an autosomal dominant mutation in 150,000 births in the united state. you find 3 instance of the mutation.
what is the mutation rate of this gene per gamete?
a. 1 mutation per 300,000 gametes
b. 1 mutation per 150,000 gametes
c. 1 mutation per 50,000 gametes
d. 1 mutation per 450,000 gametes
e. 1 mutation per 100,000 gametes

the concept of nucleosome occupancy, which reflects the fraction of cells from the population in which a given region of dna is occupied by a histone octamer

a and c are the answeres

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.
