Read each question carefully and answer to the best of your ability. This worksheet covers various aspects of non-Mendelian inheritance patterns.
1. In snapdragons, red flowers (RR) crossed with white flowers (WW) produce pink flowers (RW). This is an example of:
Complete dominance
Incomplete dominance
Codominance
Multiple alleles
2. Human ABO blood types are an example of:
Incomplete dominance
Sex-linked inheritance
Codominance and multiple alleles
Polygenic inheritance
3. When two different alleles are both expressed fully in the phenotype, the inheritance pattern is called .
4. Traits that are controlled by more than two alleles are said to have .
5. A trait influenced by many genes, resulting in a continuous variation of phenotypes, is known as inheritance.
6. Incomplete dominance results in a blended phenotype.
True
False
7. Sex-linked traits are more common in females than in males.
True
False
8. What is the main difference between incomplete dominance and codominance? Provide an example for each.
9. Explain why the ABO blood group system is considered an example of both multiple alleles and codominance.
10. Observe the image below showing the structure of DNA. How does the arrangement of genetic material within DNA relate to the concept of alleles and inheritance patterns, especially in the context of non-Mendelian traits?
