Which of the following terms are defined correctly?

Term Definition
i Heredity The passing on of characteristic from parents to their young.
ii Life cycle The different stages of development of a living thing from a fertilised egg to an adult that can reproduce and die eventually. 
iii Reproduction  The fusion of a sperm and an egg.

  1. i and ii only

  2. i and iii only

  3. ii and iii

  4. i ii and iii
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • The passing on of traits from the parents to their offsprings by reproduction (asexual or sexual) is called heredity.
  • The life cycle of an organism can be defined as a sequence of life stages or events an organism undergoes from birth to reproduction.
  • Reproduction is the process by which new organisms or offspring are produced by their parents
  • The fusion of male and female gamete is called fertilization.
  • So, the correct answer is 'i and ii only'.

Germplasm concept was proposed by

  1. Mendel

  2. De Vries

  3. Aristotle

  4. Weismann
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The term germplasm was first used by the German biologist August Weismann. His germplasm theory states that multicellular organisms consist of germ cells that contain and transmit heritable information and somatic cells which carryout ordinary bodily functions. In the germplasm theory, inheritance in a muticellular organism only takes place by means of the germ cells: the gametes, such as egg cells and sperm cells. Other cells of the body do not function as agents of heredity.

Who first proved that heredity is controlled by nucleus not by cytoplasm?

  1. Hershay and Chase

  2. Strassburger

  3. Hammerling

  4. Mendel
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Hammerling began growing acetabularia in laboratories in the 1930s. There he discovered that the plant had one cell and the nucleus was always located in the rhizoid. Then he began studying the roles of the nucleus and cytoplasm by experimenting with the acetabularia. He demonstrated that nucleus has the genetic material which regulates the inheritance of characters.

So, the correct answer is option C.

Mendelism is related with______________

  1. Heredity in living beings

  2. Meiosis during sexual reproduction

  3. Mutations in living organisms

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Mendel is widely considered a pioneer in the field of genetics. Gregor Mendel, known as the "father of modern genetics," was born in Austria. A monk, Mendel discovered the basic principles of heredity through experiments in his monastery's garden. 
  • His experiments showed that the inheritance of certain traits in pea plants follows particular patterns, subsequently becoming the foundation of modern genetics and leading to the study of heredity.

The transmission of characters from the parents to their offspring is called as

  1. Heredity

  2. Speciation

  3. Natural selection

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Heredity is the passing of phenotypic traits from parents to their offspring, either through asexual reproduction or sexual reproduction. This is the process by which an offspring cell or organism acquires or becomes predisposed to the characteristics of its parent cell or organism. 
Speciation is the evolutionary process by which new biological species arise. The biologist Orator F. Cook was the first to coin the term 'speciation' .
Natural selection is the differential survival and reproduction (i.e., fitness) of individuals that differ in phenotype. It is a key mechanism of evolution.

An individual can pass on to its progeny the experiences of its lifetime.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Inherited characters are the characters which is mainly passed from parents to offspring's. Genes are the fundamental unit which carries the information from one generation to the other.
The experiences of life cannot be passed from one generation to another so it cannot be inherited. The experience is created by the situations which can be learnt by training. For example, colour of the eye is inherited character while cooking is an experience and art which can be gained through the training and external exposure.

Which among the following deals with study of heredity?

  1. Resemblances and differences between the parents and offsprings

  2. Differences between the parents and the offsprings

  3. Resemblances between the parents and the offsprings

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Heredity can be defined as the passing of traits from parents to their offspring, either through asexual reproduction or sexual reproduction. This is the process by which an offspring cell or organism acquires or becomes predisposed to the characteristics of its parent cell or organism. Through heredity, variations exhibited by individuals can accumulate and cause some species to evolve through the natural selection of specific phenotype traits. The study of heredity in biology is called genetics, which includes the field of epigenetics. Study of heredity deals with resemblances and differences between the parents and offsprings. Thus, option A is correct and other options are wrong.

Cats produces cats. This statement is an explanation for

  1. Heredity

  2. Evolution

  3. Ontogeny recapitulates phylogeny

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Cats produces cats. This statement indicates the inheritance of characters from the parents to offspring. Genes are the fundamental unit which carries the characters from one generation to the other. This tendency of inheritance of genotypic and phenotypic character is known as heredity.

The transmission of traits from parents to offspring is called ____

  1. Characteristic

  2. Heredity

  3. Donation

  4. Both A and B
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

During sexual reproduction, traits from parents are transmitted to offspring. These are combinations of male and female parent. This is called heredity.
