Cross-pollination, or when pollen from one plant fertilizes another plant of the same produces outcrossing or outbreeding.

Explanation:

Cross pollination is the transfer of pollen from a plant's stamen to a different plant's stigma of the same species. They produces stronger plants. For example only pollen from a daisy can pollinate another daisy.

They have male and female reproductive units on separate plant. If they are on the same plant he pollen will not fertilize the female reproductive unit on the plant.

This process needs four steps pollination, germination, penetration of the ovule and fertilization. The Zygote divides to form an embryo after fertilization.

the level of progesterone is low at the pre-ovulatory phase of the cycle but it gradually increases and the levels are high at the luteal phase. if pregnancy occurs, the level of progesterone will be high throughout the pregnancy.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.
