Cellulose is the primary source of a cell wall which means that it doesn't come from animal sources
The right answer is law of segregation
Mendel derives from his observations two fundamental principles, to which will be added later a third resulting. In his case, experiments on peas enabled Mendel to formulate the principles involved in heredity.
<u>Mendel discovers that:</u>
* A character can present two different forms (today called alleles or homologous genes).
* An organism inherits two factors for each trait (Mendel's hereditary factors are now called "genes").
* The dominant factor masks the recessive factor. Mendel noted the dominant factor using a capital letter and the other, the recessive, using the same letter but in lower case
.
* The two factors separate during gamete formation (Segregation law that corresponds to the separation of homologous chromosome pairs during meiosis)
.
* The pairs of factors separate independently of each other (independent segregation law that corresponds to the independent assortment of chromosome pairs homologous to metaphase 1 of the first meiotic division).
