Question

Continuous self-pollination in a species may develop?

  1. Weak off springs

  2. Strong off springs

  3. New variety

  4. Seedless fruit

  5.   Removing anthers of one plant

hintHint:

Both male and female gametes share same genetic information.

The correct answer is:

Weak off springs


    • In self pollinating plants, the pollen from anther fall into the stigma of the same flower 
    • True or pure breeding is possible in self-pollination
    • Elimination of weaker qualities is not possible
    • New variety cannot be formed in self-pollinating plants since gametes share the same genetic information

    • Pollination helps in the reproduction in plants by transfer of pollen grains from anther to stigma
    • Pollination can be classified into 
    1. Self pollination: Pollen grains from anther falls into the stigma of the same flower
    2. Cross pollination: Pollen grains from anther falls into the stigma of a different flower

    Mendel’s idea that the pair of alleles of each parent separate and only one allele from each parent is passed to an offspring is explained by:

    • Law of segregation is the second law of inheritance
    • Law of inheritance is based on the following:
    1. Gene can exist in various versions called alleles
    2. During meiosis, separation of allelic pair occurs providing single allele to each gamete
    3. Organisms inherit two alleles for each phenotype
    4. In an allele pair, one is dominant while other is recessive
