- Dihybrid cross 2. A tall, purple-flowered pea plant (AaBb) is allowed to self- pollinate(The recessive alleles code for short plants and white flowers). The phenotypic ratio for the resulting offspring is 9:3:3:1. What is the genotype of the plant whose phenotype appeared once out every 16 offspring(the "1" in the 9:3:3:1 ratio?Short Answer 4. You identify two recessive mutations in fruit flies, one that results in curly wings (cc) and one in an ebony body (ee). You cross two flies that are heterozygous for both traits (CcEe), and find 352 flies progeny in the next generation with the following phenotypes: wild type - 193 wild type wings, ebony body - 69 You believe the curly and ebony alleles assort independently and are not linked. Perform a chi square analysis for this cross to test the null hypothesis.

An example of a codominant feature in certain plants is the formation of pink flowers from a red and white cross : 2.
