In tomatoes, the red fruit color is completely dominant to yellow. Suppose a tomato plant homozygous for red is crossed with one homozygous for yellow and the progeny are allowed to self pollinate. What phenotypes do you predict in the F2 generation? a) 3 red: 1 yellow b) 9 red : 3 orange : 1 yellow c) 1 red : 2 orange : 1 yellow d) 1 red : 1 yellow

The transport of pollen grains from the anther to the stigma of a flower is known as pollination. Self pollination and cross pollination are the two basic forms.
Self pollination, also known as autogamy, is the transfer of pollen grains from an anther to the stigma of a flower that is genetically identical. Closed flowers, or cleistogamous blooms, encourage self-pollination.
The passage of pollen grain from the anther to the stigma of genetically different flowers is known as cross pollination or allogamy. Dichogamy, dicliny, herkogamy, self incompatibility, and other adaptations in flowers encourage cross pollination. Pollination necessitates both abiotic and biotic agents.
