• They inherit a unique combination of traits from their parents.

• They all have the same traits as their parents.

• Traits are not inherited from parents.

• Everyone chooses their own traits.

According to the passage 'How are traits inherited?', what is the difference between inherited traits and acquired traits?

• Inherited traits are passed from parents to offspring, while acquired traits are developed during an organism's life.

• Inherited traits are learned behaviors, while acquired traits are genetic.

• Inherited traits are only found in animals, while acquired traits are only found in plants.

• Inherited traits are caused by the environment, while acquired traits are determined by DNA.

Relate Before Mendel, how did scientists believe traits were inherited?

• Scientists believed that traits blended from parents to offspring, similar to the way two colors of paint can be blended.

• Scientists believed that traits were inherited only from the mother.

• Scientists believed that traits were determined by environmental factors alone.

• Scientists believed that traits skipped every other generation.

Name three traits Mendel tracked in his hybrid experiments.

• Seed shape, pod color, and flower color.

• Leaf size, stem thickness, and root length.

• Fruit taste, plant height, and leaf color.

• Seed number, flower scent, and pod length.

What is the difference between a dominant and a recessive trait?

• A dominant trait is always expressed, while a recessive trait is only expressed when two copies are present.

• A dominant trait is only expressed when two copies are present, while a recessive trait is always expressed.

• Both dominant and recessive traits are always expressed equally.

• Dominant traits are inherited from the mother, while recessive traits are inherited from the father.
