Fruit Fly Genetics

Teaching Standard:

This module utilizes Scratch 1 on the Raspberry Pi. It simulates the number of offspring that would display the mutations of two parent flies whose genetic mutations are chosen by the user. The probability for the mutation of each offspring is determined using the Biological concept of Punnett square analysis of genes. The simulation takes into account normal genes, recessive mutations, and dominant genes. Parent flies chosen to display a dominant gene are always considered to be carriers of the normal gene. The mutations that can be chosen for the parent flies are ebony color, yellow color, curly wings, short wings, no eyes, orange eyes, and white eyes.
