DAY 5 • Last observations of embryos. How many have hatched? • Look for heartbeat. Is the blood pigmented red yet? This is caused by the formation of red blood cells (hemoglobin). • Clean out debris from petri dish. • Heredity. What is the percentage of offspring with pigment (striped) compared to those without pigment (albino). • Debriefing Report. Do your findings support your original hypothesis? • Work a Punnett Square of your cross and offspring. • Youtube Videos
Genetics of your fish • Make sure you collect ALL of the data from your particular “family” • Record final count on how many were albino/how many have melanin (the dark pigmentation scattered on embryos, including dark eyes) • Do the results match your hypothesis? Why or why not?
