Answer:
B. DR, Dr, Rd, dr
Explanation:
This question involves two genes. Alleles D and R are dominant over alleles d and r. These two genes obey the law of independent assortment as proposed by Gregor Mendel.
Based on the question, a genotype RrDd will produce the following combination of gametes following the process of meiosis:
DR, Dr, dR, dr
Typhoid fever is most common in non-industrialized countries. Travelers to Asia, Africa, Eastern Europe, and Latin America are especially at risk. Salmonella typhi bacteria are shed in the urine or stool of infected persons, including chronic carriers. There are no known animal reservoirs for typhoid fever.

The origin of the Moon refers to several explanations regarding the formation process of the Moon, Earth's natural satellite. Theory The large collision hypothesis is the best-known theory regarding the origin of the moon.
<h2>Further explanation
</h2>
The big collision hypothesis theory states that the Moon was formed from debris left over from a collision between Earth and an object the size of the planet Mars, about 4.5 billion years ago. The object that crashed into the Earth is often called Theia taken from the Greek Titan myth, which is the mother of Selene, the goddess of the Moon.
Other hypotheses about the origin of the moon:
- Catching Hypothesis. This hypothesis says that the Moon is an object captured by the Earth.
- Cleavage Hypothesis. This hypothesis says, in the old days, the Earth was spinning very quickly throwing some of its mass.
- Accretion Hypothesis. This hypothesis says that the Earth and the Moon formed at the same time as a double system of ancient accretion disks in the Solar System.
- The Georeactor Explosion Hypothesis. Another more radical hypothesis was published in 2010, saying that the Moon might have been created by a georeactor explosion located along the boundary of the mantle's core in the rapidly rotating equatorial plane of the Earth. This hypothesis can explain the similarity of the composition of the Earth and the Moon.

That would be myology. Myology is the study of the muscular system, wlong with its nature, structure, functions and diseases. It mainly deals with the three types of muscles found in the human body: skeletal muscles, smooth muscles, and cardiac muscles. Muscles are also categorized depending on whether or not they are voluntary or involuntary. Myology is concerned with the study of all this and much more.
