Answer:
Ss × ss
Explanation:
This question involves a single gene coding for hair length in guinea pigs. The alleles for short hair (S) is dominant over that of long hair (s).
According to this question, a guinea pig with short hair (S_) is crossed to one that has long hair (ss) to produce offsprings that have 44 short hair and 46 long hair. This number of offsprings produced indicate a ratio of 1:1, which can only be produced if the short haired guinea pig is heterozygous i.e. Ss.
Therefore, the genotype of the parents are Ss (short hair) and ss (long hair) i.e. Ss × ss. This combination will produce offsprings with the following proportion: Ss (1) : ss (1).
Answer:
The cell bodies of sensory neurons that are in clusters of neurons outside the spinal cord are called ____
The answer is "dorsal root ganglia"
Explanation:
Explanations of some terms
Sensory neurons:
Sensory neurons, also known as afferent neurons, have cell bodies that are located in the dorsal ganglia (also known as spinal ganglia) of the spinal cord. Most sensory neurons have one axon which is split into two branches, they transmit impulses toward the spinal cord.
Spinal cord:
The spinal cord is a tubular structure composed of nervous tissue housed within the vertebral column, runs from the base of the brain to the lower spine. Spinal cord is a component of the Central Nervous System that serves as information highway the between brain and the body which Integrates and processes information. It can function with the brain and can also function independently of the brain.
Dorsal root ganglia:
Dorsal root ganglia also known as dorsal ganglia originated as bipolar cells. They exists within the peripheral nervous system and they have special nerve cell clusters that aid in transmitting the sensory messages of pain and touch. The dorsal root ganglia receive information from sensory receptor organs and transmitting the information to the central nervous system.
