Question

In cucumbers, dull fruit (D) is dominant to glossy fruit (d), and orange fruit (R) is dominant to cream-colored fruit (r). The gene that codes for dul versus glossy assorts independently from the gene that codes for orange versus cream-colored. A plant that has dull and orange fruits is crossed to a plant that has dull and cream-colored fruits. The cross produces eight total progeny, with three plants that have dull and orange fruits, three plants with dull and cream-colored fruits, one plant with glossy and orange fruits, and one plant with glossy and cream-colored fruits Give the genotypes of the parents and all the possible genotypes of the offspring of the cross Parental DDR DDrr DdRR DdRr Ddrr ddRR ddRr ddm DDRR Phenotype dull, orangedull, cream- colored Genotype F1 Phenotype orange colore dull cream glossy orange glossy cream- dull colored Genotype

Explanation / Answer

Parental Genotype :-it is DdRr and Ddrr F1 Genotype is found to be DDRr, DdRr, DdRr( dull orange) DDrr, Ddrr, Ddrr (Dull cream) ddrr(glossy cream) ddRr(glossy orange) The eight progeny thus produced there Genotype is right above. As assortment of the gene is parallel to the assortment of chromosomes there parents carry the different Genotype.
