How Structure and Function is Affected by Mutations in Blind Fish Eyes Scales Taste Cells Lateral Line 2- Model to explain what causes these changes:
Based on standard MS- LS3-1:
Fish in a cave system in Mexico is missing its eyes, has thin, translucent skin, and is relatively small (7-10 cm in length).
Can you describe by model why structural changes to genes (mutations) on chromosomes may affect proteins and may result in beneficial effects to the structure and function of the fish?
