This is just a dominant allele of the green color trait. The dominance can be confirmed by seeing the commonality of individuals who express the green color trait as having a dominant allele(W) and the ones without(w), not green. This is not X-linked because the letters which dictate the allele do not contain the X character with the a superscript indicating it as a sex-linked trait.
The size of plasmids ranges between 1 and 200 kbp (kilo-base pairs) and a DNA fragment that can be inserted into a plasmid vector is up to 20 kbp. Artificially constructed plasmids are often used as vectors in genetic engineering to clone and amplify (or express) particular genes.
The term that represents the X letter is an organism (organismic level).
<h3>What is an organism?</h3>
In ecology, the organism level represents the fundamental unit that interacts in a particular ecosystem.
The ecosystem level is composed of organism and abiotic factors (e.g., temperature, water resources, etc) that interact to shape a given environment.
In conclusion, the term that represents the X letter is an organism (organismic level).
