Chicken Feather Color Inheritance Diagram - Mendelian Genetics Example #117459 (License: Personal Use)

The diagram depicts a cross between a homozygous black rooster (DD) and a homozygous white rooster (RR), producing uniformly mottled (D(R)) F1 offspring. When F1 individuals are interbred, the F2 generation shows a 1:2:1 phenotypic ratio-black (DD), mottled (D(R)), and white (RR)-demonstrating codominant inheritance. Each genotype is clearly labeled with corresponding visual representations of feather coloration.

Used in biology education materials, genetics textbooks, or online science resources to teach Mendelian inheritance, particularly codominance. Matches user intent for understanding Punnett squares, phenotype ratios, and real-world examples of genetic principles.
