Science
(i) In a cross between violet flowered plants and white flowered plants, state the characteristics of the plants obtained in the F1 progeny.
(ii) If the plants of F1 progeny are self-pollinated, then what would be observed in the plants of F2 progeny ?
(iii) If 100 plants are produced in F2 progeny, then how many plants will show the recessive trait ?
Answer
(i) In a cross between violet flowered (VV) plants and white flowered (vv) plants, the plants obtained in the F1 progeny will bear purple flowers as purple flower is dominant trait. Genotype of the F1 progeny will be heterozygous (Vv).
(ii) If the plants of F1 progeny are self-pollinated, the plants in F2 generation will be purple flowered and white flowered in a ratio of 3:1
(iii) If 100 plants are produced in F2 progeny, then 25 plants will show the recessive trait.
