Answer:
28 units
Explanation:
This disorder follows quantitative inheritance. It is controlled by three genes which do not show the usual dominant-recessive relationship . The six alleles individually contribute to the effect which add up to produce the cumulative phenotype. Dominant allele contributes 6 units of risk whereas recessive allele contributes 2 units of risk.
Individual with genotype AABbCc has four dominant alleles (AABC) and two recessive alleles (bc). So their total risk units =
(6*4) + (2*2) = 24 + 4
= 28 units
Answer:
Pleurisy
Explanation:
Pleurisy is a medical condition caused by the inflammation of the pleura membranes. The pleural membranes are vital part of the respiratory system. These membranes which surround the lungs and lines the inner chest wall, help to give cushion and reduce friction in the lungs. When the pleural membranes become inflamed, the surfaces become tough and sticky, thereby causing the sharp pain the person feels in the chest while breathing.
You end up with a polyploid condition. Not uncommon in organisms, especially plants, like angiosperms.
Look up "polyploidy".
The correct answer is C. The right side of the heart delivers deoxygenated blood (from vena cava) to the lungs (via pulmonary artery)
