Biology Quiz on Dihybrid Crosses

What is the main difference between monohybrid and dihybrid crosses?

• Monohybrid crosses are more complex than dihybrid crosses.

• Monohybrid crosses are used for plants, while dihybrid crosses are used for animals.

• Monohybrid crosses involve one trait, while dihybrid crosses involve two.

• Monohybrid crosses involve two traits, while dihybrid crosses involve one.
