Suppose only one gene with 2 alleles determines a particular trait but the alleles are codominant. how mant different phenotypes
Leona [35]

The answer is one trait. In Codominant alleles, neither allele is dominant over the other. Both alleles are expressed equally hence no recessive or dominant phenotypes. An example of that of fur color in rabbits where one  parent with black fur color and the other with white fur color will produce offspring of black and white fur color. This should not be confused with incomplete dominance  whre the two alleles blend in phenotype.Example of incomplete dominance is a parent with straight hair in humans and another with curled hair will produce wavy hair offsprings.

Pepsinogen is produced by __________ and is activated by __________
Ket [755]

Answer:

Pepsinogen is produced by chief cells and is activated by hydrochloric acid secreted by parietal cells.

Explanation:

Pepsinogen is a proenzyme produced in the chief cells (that are located in the stomach lining) that, when gets activated, is transformed into pepsin - a peptidase with the function to degrade proteins into amino acids.

The reason why pepsinogen is released inactive is that it would break down all of the cell's proteins because of its proteolytic nature. For this reason, it is released as a proenzyme and gets activated when reaches the acidic environment provided by the hydrochloric acid secreted by the parietal cells, also in the stomach lining.
