Non-Mendelian Genetics

What is the term used to describe genetic inheritance patterns that do not follow Mendel's laws?

• Non-Mendelian Genetics

• Mendelian Genetics

• Classical Genetics

• Chromosomal Genetics

Who was the scientist that studied pea plants to understand patterns of heredity?

• Charles Darwin

• Gregor Mendel

• Louis Pasteur

• Isaac Newton

Why were pea plants great organisms for Gregor Mendel to use in his experiments on heredity?

• They grow very quickly

• They have simple patterns of heredity

• They are easy to find in the wild

• They produce large fruits

What important discovery did Mendel make by studying pea plants?

• All traits (alleles) are inherited equally

• One trait (or allele) is always dominant over the other

• Traits (alleles) are only inherited from the mother

• Pea plants can change their traits (alleles) over time

Suppose you are designing an experiment to study heredity. Based on Mendel’s approach, what kind of organism would be most useful?

• An organism with complex patterns of heredity

• An organism with simple patterns of heredity

• An organism that cannot reproduce

• An organism with unpredictable traits

Which of the following is an example of a trait that does NOT follow Mendel’s rules?

• Codominance

• Dominant-recessive inheritance

• Simple Mendelian inheritance

• Monohybrid cross

Which of the following is NOT listed as an exception to Mendel’s rules in the provided material?

• Incomplete dominance

• Sex-linked traits

• Multiple alleles

• Monohybrid inheritance

If a scientist observes a trait that is influenced by more than one gene, which term from the material best describes this trait?

• Polygenic trait

• Codominance

• Sex-linked trait

• Incomplete dominance

Explain why some traits do not follow Mendel’s rules, using one example from the material.

• Because traits like codominance involve both alleles being expressed, which is different from Mendel’s dominant-recessive pattern.

• Because all traits always follow Mendel’s rules.

• Because Mendel’s rules only apply to animals, not plants.

• Because Mendel’s rules are outdated and no longer used.

What is codominance?

• When two alleles are fully expressed at the same time

• When only one allele is expressed

• When neither allele is expressed

• When alleles are always recessive
