Prepare an infographic focused on genetics, highlighting traits that "break the rules" of Mendel. Please follow the instructions below and be sure to follow APA formatting guidelines
Instructions:
In Module 4, we learned about genetics, including traits that “break the rules” of Mendel. For this assignment, you will create an infographic that communicates the information below. See the attached handout to view resources that can assist you in creating some of these deliverables.
- Create a deliverable that addresses two (2) traits that "break the rules" of Mendel from the categories listed below.
• Codominance
• Incomplete Dominance
• Multiple Alleles
• Sex-Linked
• Recessive Lethal
- For each category selected, make sure to correctly name the trait, how it fits into the category, and how often the trait is seen among living organisms. Your examples must be different from those presented in the textbook.
• This might include the chromosomal location
• And/or the number of alleles (e.g., spots where the traits are located on the chromosomes
• And/or the “mixture” of the alleles
• And/or how the trait is diagnosed (if a disease or condition)
- Pictures and other graphics are welcome, but if they are not your own be sure to CITE where you found the information (remember your examples must be different from those presented in the textbook).
Title: Traits that “Break the Rules” of Mendel
Introduction: In the field of genetics, there are certain traits that do not follow the patterns of inheritance described by Gregor Mendel. These traits exhibit unique characteristics that challenge the traditional Mendelian principles. This infographic will explore two such traits from different categories, providing an understanding of their nature, prevalence, and distinctive features.
Trait 1: Codominance
Name: ABO Blood Group
Category: Codominance
Prevalence: Seen in all human populations
Explanation:
The ABO blood group is determined by the presence or absence of antigens on the surface of red blood cells.
There are three alleles involved in this trait: A, B, and O.
Individuals with allele A express antigen A, those with allele B express antigen B, and those with allele O do not express any antigens.
If an individual inherits both A and B alleles, codominance occurs, resulting in expression of both antigens.
The ABO blood group system is crucial in determining blood compatibility for transfusions and organ transplants.

Trait 2: Incomplete Dominance
Name: Snapdragon Flower Color
Category: Incomplete Dominance
Prevalence: Common among flowering plants
Explanation:
Snapdragon flowers exhibit incomplete dominance in their color inheritance.
The trait involves two alleles: Red (RR) and white (WW).
When a plant inherits one red allele and one white allele (RW), the resulting flower color is pink.
This intermediate phenotype occurs due to a blending of the red and white pigments.
This phenomenon can be observed in various other plant species as well.

Conclusion:
Although Gregor Mendel’s laws of inheritance serve as a foundation in genetics, there are several traits that deviate from these principles. Codominance and incomplete dominance are two such examples. The ABO blood group and Snapdragon flower color illustrate how these traits break the rules of Mendel. Understanding these exceptions broadens our knowledge of genetics and highlights the complexity of inheritance patterns.
