1. Why do all living organisms require energy?
All organisms require energy to perform life processes such as reproduction,
You are a geneticist working with a newly discovered strain of dragons. You have seen
red dragons and green dragons. You are trying to determine which color is the dominant
color. Your lab group has been breeding the dragon
Mendel is well known for his contributions to genetics. However, the work that Mendel
performed only detailed how completely dominant traits would be passed on to offspring. More
research into genetic showed that there were
1. In superheroes, having the ability to fly is recessive. Non-flying is the dominant trait.
Cross a hybrid non-flying superhero with a flying superhero. What are the genotypic and
phenotypic ratios of their possible offspring?
