The structural organization of autonomic nervous system or ANS is different from somatic nervous system or SNS.

In the ANS, the motor neurons of the central nervous system do not directly control visceral effectors. They synapse with visceral motor neurons or preganglionic neurons in ganglia, and the ganglionic neurons control the visceral effectors.

Coat color in rabbits is under the control of a single gene with

Mashcka [7]

Answer: a) Cch x Ccch

b) Ccch x Cc

c) Cch x cchch

d) cchc x chc

Explanation:

Data:

Coat color in rabbits is under the control of a single gene with

four alleles: C (full gray color); cch (chinchilla, light gray); ch

(Himalayan, white with black extremities); and c (albino, absence

of pigmentation).

The dominance hierarchy is represented as: C >cch > ch > c.

Possible genotypes:

For full gray color: CC (Gray), Ccch (Gray-2), Cch (Gray-1), Cc (Gray-3). The allele "C" dominates over the other three alleles, so in every combination where "C" is present, the animal will be fully grayed.

For light gray color/Chinchilla: cchcch (Chinchilla), cchch (Chinchilla-1), cchc (Chinchilla-2). The allele "cch" dominates over "ch" and "c", but not over "C". So if the allele "C" is combined with "cch", the animal will be fully grayed, but in any other combination with "cch", the animal will be light grayed.

For white with black extremities/Himalayan: chch (Hymalayan), chc (Hymalayan-1). The allele "ch" that determines the Himalayan color is only dominant over the allele "c". But in combination with any other allele, "ch" behaves as a recessive one.

For albino: cc. In the presence of any of the other alleles, the allele "c" always behaves as a recessive one. The only possibility of getting an albino animal is if "c" combines with another "c".

Tanya [424]

Answer:

Principle of diminishing returns

Explanation:

In this case, Initial inputs of energy, water, fertilizer, and pesticides on high-yield crop varieties would produced high crop yields. As time goes on further adidtion of these same inputs of production would give the same or a lower yields of crops. Therefore, obeying the Principle of diminishing returns.
