In the radish plant, the long and round traits exhibit lack of dominance and the heterozygotes have an oval shape. the red and white color traits also exhibit lack of dominance and heterozygotes have a purple color. two oval-shaped, purple plants are crossed. what phenotypic ratio would the offspring show?

1 long and red: 2 long and purple: 1 round and red: 2 oval and red: 4 oval and purple: 2 oval and white: 1 round and red: 2 round and purple: 1 round and white

Explanation:

According to the given information, color and shape are incompletely dominant traits in the radish plant. Let's assume that allele L imparts long while allele "l" imparts round phenotype. Therefore, the genotype Ll will give an oval phenotype. Genotype LL and ll will give long and round shapes respectively.

Likewise, allele R gives red and allele r gives white color. The heterozygote Rr will exhibit a purple color. Genotypes RR and rr will give red and white colors respectively. The genotype of oval-shaped, purple plants will be LlRr.

A cross between two LlRr plants will give the progeny in following phenotype ratio=1 long and red: 2 long and purple: 1 round and red: 2 oval and red: 4 oval and purple: 2 oval and white: 1 round and red: 2 round and purple: 1 round and white
