9.Wing spot colouration in a hypothetical butterfly population is controlled by a single locus.
Blue spotted individuals have the genotype SBSB;
Yellow spotted individuals have the genotype SYSY; and
Green spotted individuals have the genotype SBSY;
Ten years ago, a museum randomly collected 1000 butterflies and reported finding 90 blue, 490 yellows, and 420 greens.
This year, the same museum randomly collected 1000 butterflies and reported 40 blues, 640 yellows, and 320 greens.
Has there been evolution in this population? If yes, is natural selection involved? Explain and justify your answers.
