Red fish (RR) × White fish (R'R')
In genetics, the study of inheritance patterns is crucial in understanding the diversity of life on Earth. Two essential concepts in genetics are codominance and incomplete dominance, which describe the interactions between different alleles of a gene. In this article, we will explore these concepts in-depth, provide a practice worksheet, and offer an answer key specifically designed for a fish-themed example. Red fish (RR) × White fish (R'R') In
: Alleles blend to create a new, intermediate phenotype (e.g., a red fish and blue fish producing purple offspring). Codominance : Alleles blend to create a new, intermediate phenotype (e
Look for "in-between" descriptions like pink, medium, wavy, or blended. Instead, the heterozygous phenotype is a or intermediate
In incomplete dominance, neither allele is completely dominant over the other. Instead, the heterozygous phenotype is a or intermediate of the two homozygous phenotypes.
