To analyze:
Why planting potatoes may be preferable to planting potato seeds, and which potatoes must be chosen for planting.
Introduction:
Potatoes can reproduce through both sexual and asexual means.

Explanation of Solution
Potatoes can reproduce sexually, by flowering, pollination and seed production. These seeds can give rise to new plants. However, new potato plants can be obtained by planting potatoes from the parent plant. This is a form of asexual reproduction, and the new plant will be genetically identical to the parent. The farmer can therefore choose to plant potatoes that yield more and are tolerant to environmental stresses. Planting potatoes may be preferable, since the genetic composition of the plant is preserved in asexual reproduction. Potatoes which possess the characteristics that the farmer wants will be chosen for propagation.
Planting potatoes that are adaptable to their environment and tolerant to stresses may be preferable, since the genetic composition of the plant is preserved in asexual reproduction. The farmer will choose the potatoes with the characteristics that she/he wants to propagate in the next crop, such as high yielding or stress tolerant potatoes.

- Noggin mutation: The mouse, one of the phenotypic consequences of Noggin mutationis mispatterning of the spinal cord, in the posterior region of the mouse embryo, suchthat in the hindlimb region the more ventral fates are lost, and the dorsal Pax3 domain isexpanded. (this experiment is not in the lectures).a. Hypothesis for why: What would be your hypothesis for why the ventral fatesare lost and dorsal fates expanded?
