Answer:
a. different alleles of the seed shape gene.
Explanation:
Mendel crossed different varieties of pea plants and he observed how phenotypic traits passed to the progeny. From these experiments, Mendel formulated the 'First Law of Segregation', where he observed that traits may exist in pairs that segregate (separate) at meiosis. During meiosis, i.e., gamete formation, these two factors separate from each other, thereby each gamete has the same probability of receiving either factor. Nowadays, we know that these two factors represent two different gene variants or 'alleles' for a given gene <em>locus</em>. Alleles can be classified into dominant or recessive as in the example above described, where the R factor (round) dominates on the r factor (wrinkled) to determine the seed shape.
Body composition:<span>is the percentage of person's total body weight that is made up of adipose (fat) tissue as opposed to lean body tissue is known as their body composition. Disease risk is closely related to body composition.

Answer:
The advantage of this is that there is a larger surface area exposed, more time available and shorter difference for exchange of oxygen.
