The answer is in the question. It's called imprinting.
The correct answer is stabilizing selection.
Stabilizing selection is a kind of natural selection in which the mean of the population steadies on a specific non-extreme trait value. This is considered to be the most general process of action for natural selection as the majority of the traits do not seem to vary radically with time.
Stabilizing selection is the reverse of disruptive selection. In spite of preferring individuals with extreme phenotypes, it favors the transitional variants. Stabilizing selection seems to eradicate the more extreme phenotypes, resulting in the reproductive success of the average or norm phenotypes.
This signifies that the most general phenotype in the population is chosen and continues to govern in the coming generations. As the majority of the traits vary slightly with time, stabilizing selection is considered to be the most usual kind of selection in the majority of the populations.
From the pith outward, if you looked at a cross-section of a eudicot plant stem, you would see Xylem, vascular, cambium, and phloem in that order. The vascular cylinder divides the ground tissue into two discrete areas and is structured in a ring in eudicot stems.
The pith refers to the area of ground tissue that is included within the vascular cylinder. In general, eudicots possess three or more of the following traits: There are 2, 4, or 5 flower parts, or multiples of 4 or 5, and leaves have netted venation (pinnate or palmate). A ring of stem vascular bundles surrounds the pith, and seeds have two seed leaves (cotyledons).
As a result, we can assert that if you cut a cross-section of a eudicot plant stem, Xylem, vascular, cambium, and phloem in that order, you will find various plant tissues from the pith outward.
