Gregor Mendel mixed different types of peas to bring out their desirable traits. This mixing to produce a better crop is called:
|
|
Pollination.
|
|
|
Gene therapy.
|
|
|
Composting.
|
|
|
Selective breeding. (Hybridization)
|
Explanation:
Detailed explanation-1: -Mendel crossed pure lines of pea plants. Dominant traits, like purple flower colour, appeared in the first-generation hybrids (F1), whereas recessive traits, like white flower colour, were masked. However, recessive traits reappeared in second-generation (F2) pea plants in a ratio of 3:1 (dominant to recessive).
Detailed explanation-2: -With controlled fertilization, Mendel bred generations of pea plants with the confidence that there was little or no contamination from plants of other generations. Mendel managed mating by removing the reproductive organ of a flower (piston) from one plant and pollinating another plant of his choice.
