Organism produced by asexual reproduction are called

  1. clones

  2. offsprings

  3. factors

  4. both (A) and (B)
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Since the organisms produced by asexual reproduction are completely identical to the parents due to no variation, they are called clones.

So, the correct option is  'clones'.

A 'clone' is defined as a collection of genetically _________________.

  1. Different individuals produced by sexual reproduction

  2. Different individuals by vegetative reproduction

  3. Identical individuals by sexual reproduction

  4. Identical individuals by vegetative reproduction

D Correct answer
Explanation

A clone is scientifically defined as a group of genetically identical individuals derived from a single common ancestor, typically produced through asexual or vegetative reproduction methods.

Clones do not appear during.

  1. Cuttings

  2. Budding

  3. Grafting

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

Clones are the result of asexual reproduction. Seed propagation involves sexual reproduction (fertilization), which introduces genetic recombination and variation, meaning the offspring are not clones.

Assertion: Clones are produced by sexual reproduction and same sexual process.

Reason: These are prepared by group of cells descended from many cells or by inbreeding of a heterozygous line

  1. If both the assertion and the reason are true and the reason is a correct explanation of the assertion

  2. If both the assertion and reason are true but the reason is not a correct explanation of the assertion

  3. If the assertion is true but the reason is false

  4. If both the assertion and reason are false

  5. If the assertion is false but reason is true
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Clones are asexually produced. These have same genotype and phenotype like parent.

So, the correct answer is 'If both the assertion and reason are false'

Choose the most appropriate option:
Clones of animals are being produced through the practice of-

  1. genetics

  2. ecology

  3. embryology

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

The production of animal clones, such as through somatic cell nuclear transfer, relies heavily on advanced technological applications in biology, making biotechnology the most accurate choice among the options.

Match column I with column II and select the correct option from the codes given.

Column I Column II
A. Planaria (i) Binary fission
B. Fungi (ii) Asexual spores
C. Yeast (iii) Budding
D. Amoeba (iv) True regeneration
(v) Fragmentation
  1. $A-(i), B-(ii), C-(iii), D-(iv)$
  2. $A-(iv), B-(ii), (v), C-(iii), D-(i)$
  3. $A-(ii), B-(v), C-(i), D-(iv)$
  4. $A-(v), B-(ii), (i), C-(iii), D-(iv)$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
 Column I  Column II
 A. Planaria  (iv) True regeneration
B.  Fungi  (ii) Asexual spores (v) Fragmentation
C. Yeast  (iii) Budding
 D. Amoeba  (I) Binary fission
   

Correct match following are given in table.

So the correct option is "A-(iv), B-(ii),(v), C-(iii), D-(i)".

The phenomenon observed in some plants where in parts of the sexual apparatus is used for forming embryos without fertilisation is called.

  1. Parthenocarpy

  2. Apomixis

  3. Vegetative propagation

  4. Sexual reproduction
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Apomixis is the term given to any phenomenon that leads to formation of embryo wherein parts of the sexual apparatus are used, but without fertilisation. Fertilisation is also absent in vegetative propagation, but parts of sexual apparatus are not involved. An example of apomixis is Citrus.
