Concept

Problem: Eggplant fruit color may be dark purple, violet, or white. Crosses between purple and white eggplants always produce violet eggplant progeny. However, the crossing of these violet eggplants gives the following progeny: 110 violet, 54 purple, and 56 white eggplants. What is the genetic basis of fruit colors in eggplants?

FREE Expert Solution

Being a product of the cross between the dark purple and white eggplants, violet eggplants are most probably the heterozygous type. Showing neither of the parents' phenotype, this shows that the allele has incomplete dominance.
