The spinal cord is a soft bundle of nerves that extends from the base of the brain to the lower back. It runs through the spinal canal and is protected by the bones of the spine (vertebrae). Messages between the brain and the nerve roots travel up and down the spinal cord, making it possible for the brain and body to communicate. The discs cushion the vertebrae and provide flexibility to the spine and spinal cord.

In garden peas, the axial (A) flower position is completely dominant to the terminal (a) flower position. You cross a true-breed

xxTIMURxx [149]

Answer:

Explanation:

A true breeding organism for a particular trait is an organism that would produce progeny with the same trait whe self fertilized.

Hence, since axial flower is represented by the allele A, a true breeding flowering plant will have the genotype AA.

Axial flower (A) is dominant over terminal flower (a).

True-breeding axial flowering plant will have the genotype AA.

True breeding terminal flowering plant will have the genotype aa.

AA is crossed with aa.

AA x aa

offspring: Aa, Aa, Aa and Aa.

All the offspring will exhibit axial flowering.
