Fish _verified_ - Codominant Incomplete Dominance Practice Worksheet Answer Key

In the "Codominant/Incomplete Dominance Practice Worksheet," the section featuring fish typically focuses on codominance

: Alleles blend to create a new, intermediate phenotype (e.g., a red fish and blue fish producing purple offspring). Codominance

1 BB : 2 BY : 1 YY

In a different fish species, and Yellow (Y) alleles are codominant.

Understanding genetic inheritance patterns like codominance and incomplete dominance is easier when you visualize how traits mix or show up together. In fish, these patterns often dictate scale color and fin shape. Quick Definitions intermediate phenotype (e.g.

In a certain fish species, and White (R') alleles show incomplete dominance.
