Law of independent assortment states that when two pairs of independent alleles enter into combination in the F2 generation, they exhibit independent dominant effects. It means that during the formation of gametes, the law of segregation operates but the factors assort themselves independently at random and freely. So, for explaining this principle a monohybrid cross will be insufficient. We will need a dihybrid cross to depict this. Thus, this is the correct answer.

Uracil is present only in RNA. In DNA, Thymine is present in place of Uracil.

Replication is the formation of new DNA molecules from parent DNA during cell division.

Radiolaria has1600 chromosomes in its diploid stage.

t-RNA molecule has a peculiar shape which acts as an adapter during translation.

The tibialis anterior muscle in humans is percepted from the L4-S1 roots, particularly the L5 and to a lesser extent L4 root through the sciatic and ultimately the deep peroneal nerves.

Bacteria are prokaryotic, so they do not have a membrane enclosed nucleus.

Common peroneal nerve dysfunction is due to damage to the peroneal nerve resulting in the loss of movement in the foot and leg. It supplies movement and sensation to the lower leg, foot and toes. When Raman met with an accident and had a fracture at the neck of fibula, the common peroneal nerve must have been damaged.

The inner membrane forms a number of infoldings into the cavity of mitochondrion. These folds are called cristae or cristae chondrialis.

Quantasome is the globular particle seen within the thylakoid membrane carrying out photochemical reaction during photosynthesis. Each quantasome is composed of about 200 to 300 chlorophyll molecules.

Ptosis takes place in individual when the muscles that raise the eyelid, i.e. levator muscles is not strong enough to raise the eyelid. Frequently, it can be caused by the aponeurosis of the levator muscle and nerve abnormalities trauma.

In humans, the flexor digitorum profundus is innervated by the ulnar and median nerves and supplied the ulnar artery and the radial artery.

Celiac ganglion is the largest group of sympathetic prevertebral ganglia on the upper part of the abdominal aorta on either side of the celiac artery, containing the sympathetic neurons. The axons of the greater and least splanchnic nerves synapse on the postganglionic neurons located in the celiac ganglion.

To define simple aquatic plants, the term phycology or algology is used.

 When a ray of light passes from one medium to another refraction occurs, that is, the ray is bent at the interface. The direction and magnitude of bending is determined by the refractive indexes of the two media forming the interface.

The median nerve is formed from parts of the medial and lateral cords of the brachial plexus. An injury to the median nerve at the elbow may cause symptoms to appear in the forearm, wrist and hand. Injuries to the median nerve are either lesions where the nerve is torn either partially or fully. The above question is an example of the median nerve injury.
