QUESTIONS(1 SHORT SIMPLE SENTENCE EACH): ANALYZE AND INTERPRET DATA
1)USE MODELS: determine whether each offspring is white or red. The calculate the percentage of offspring for each color

2)REFINE YOUR PLAN:How would you revise this investigation to stimulate the crossing of two genes each with two alleles

Answer 1

1) The offspring results indicate that approximately 66.6% were red (dominant) and 33.3% were white (recessive).

2) To revise this investigation, I would simulate the crossing of two genes, each with two alleles, using a dihybrid cross to observe the inheritance patterns of both traits simultaneously.
