Answer:
Purple colour arises due to the dominant alleles whereas white colour arises due to the recessive alleles.
For the purple colour to arise, even one of the dominant allele will be enough to cause the effect. On the other hand to see the recessive white trait, both the alleles of the gene should be recessive.
To ensure that only white flowers are grown, the farmers need to cross both white flowered plants to get the desired result.
<span>This is probably caused by ill-fitting shoes putting pressure on certain areas of the foot and would be called a Corn.
In this context, corn refers to some sort of calluses that appear if we constantly use ill-fitting shoes. The pressure that caused by the ill-fitting shoes will create some sort friction that will make the skin on that area become thicken.</span>
The respiratory and circulatory systems are close together by working and relying with each other. The respiratory system imports oxygen from the air and that oxygen goes through out the body by the circulatory system pumping the oxygen. That creates carbon dioxide, which the respiratory exports from the body.
