The type of inheritance in which the phenotype of the offspring is intermediate between the two parents is called: MCQ with Answer and Explanation

The type of inheritance in which the phenotype of the offspring is intermediate between the two parents is called:
A. Complete dominance
B. Incomplete dominance
C. Codominance
D. Polygenic inheritance
Answer: Option B
Solution (By JKSSB Mock Tests)
Incomplete dominance occurs when neither allele is completely dominant, resulting in a heterozygous phenotype that is a blend (e.g., red × white snapdragons produce pink). Codominance shows both alleles fully expressed (e.g., AB blood type). Complete dominance shows one allele masking another. Polygenic inheritance involves multiple genes contributing to a continuous trait.

Question #1
Who is known as the father of Binomial Nomenclature?
A. Robert Whittaker
B. Charles Darwin
C. Aristotle
D. Carolus Linnaeus

Correct Answer: Option D


Explanation:
Carolus Linnaeus, a Swedish botanist, is known as the father of Binomial Nomenclature. He introduced this system of naming organisms using two terms: the generic name and the specific epithet. This standardized naming system eliminated the confusion caused by local and common names across different languages and regions.

Question #2
Consider statements about human anatomy: 1. The heart pumps blood throughout the body. 2. The lungs exchange oxygen and carbon dioxide. 3. The kidneys produce urine. Which are correct?
A. 2 and 3 only
B. 1 and 3 only
C. 1 and 2 only
D. 1, 2 and 3

Correct Answer: Option D


Explanation:
The heart is a muscular pump that circulates blood through the cardiovascular system, delivering oxygen and nutrients to tissues and removing waste. The lungs are the primary organs of the respiratory system, where gas exchange occurs: oxygen diffuses from the alveoli into the blood, and carbon dioxide diffuses from the blood into the alveoli to be exhaled. The kidneys are the primary excretory organs, filtering blood to remove metabolic waste, excess water, and ions, producing urine. All statements are correct.

Question #3
In the human body, the 'Hypothalamus' is a small but crucial region of the brain that links the nervous system to the endocrine system via the:
A. Pituitary gland
B. Spinal cord
C. Thyroid gland
D. Adrenal gland

Correct Answer: Option A


Explanation:
The hypothalamus is a small, highly complex region located at the base of the brain, near the pituitary gland. It is the primary link between the nervous and endocrine systems. It controls the pituitary gland (the 'master gland') both neurally (via the posterior pituitary, where it stores and releases ADH and oxytocin) and hormonally (via the anterior pituitary, by secreting releasing and inhibiting hormones that regulate the production of anterior pituitary hormones). Through the pituitary, the hypothalamus regulates a vast array of bodily functions.
