Answer:
C. the genes for these two characters were on different chromosomes
Explanation:
Mendel conducted several experiments with peas to demonstrate the mechanisms of heredity. He decided to use peas because they self-fertilize, have a short life cycle, are easily grown and produce large numbers of offspring. Peas, in addition to the advantages already mentioned, have simple characteristics to observe, such as the color and shape of the seed. Mendel analyzed seven of these characteristics that had no intermediates: seed texture, seed color, seed coat color, pod shape, pod color, flower position, and plant height.
Through his study, Mendel concluded that the characters "seed color" and "seed shape" showed an independent variety. This is because the genes related to these two traits are distant from each other in the chromosome and therefore have no dependence between them.
I’m pretty sure it’s the second one and the fourth one !
In biology, a mutation is the permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements. Mutations result from errors during DNA replication or other types of damage to DNA, which then may undergo error-prone repair, or cause an error during other forms of repair, or else may cause an error during replication. Mutations may also result from insertion or deletion of segments of DNA due to mobile genetic elements. Mutations may or may not produce discernible changes in the observable characteristics of an organism.
