In Drosophila Melanogaster, the common fruit fly, has long wings and red eyes. A genetics student obtained a vial of double mutant flies that have shortened wings and white eyes instead of the typical longer wings and red eyes. The student bred several generations of each fly together and obtained the following results. Phenotype Number of individuals
Long wings, red eyes 2031
Long wings, white eyes 482
Short wings, red eyes 463
Short wings, white eyes 2024

Calculate the number of map units between the genes that encode for the short wing and white eyed characters.
A. 24
B. 47
C. 19
D. 10

the answer is c. altitude. hope this ! #brainiac

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.
