Question

Intraspecific cross pollination is

• A. Allogamy
• B. Geitonogamy
• C. Xenogamy
• D. Alloautogamy

Answer 1

The correct option is A Allogamy

• Allogamy is the cross-pollination in which pollen grains are transferred from the anther of one flower to the stigma of another flower borne on a separate plant

• Geitonogamy is a type of self-pollination in which pollens are transferred from the anther of one flower to the stigma of another flower of the same plant

• Xenogamy is the cross-pollination between the flowers of different plants. It produces heterozygosity because two genetically different parents are involved

• Alloautogamy is the condition in which flowers get self-pollinated when cross-pollination fails to occur

Thus, intraspecific (means within the same species) cross-pollination is allogamy as it involves pollination between plants of same species

So, the correct answer is 'Allogamy'
