Question

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:

  1. Law of dominance

  2. Law of segregation

  3. Law of independent assortment

  4. Hybridization

hintHint:

This law helps in understanding pattern of single-gene inheritance.

The correct answer is:

Law of segregation


    • Gregor Mendel, the Father of Genetics, proposed the laws of inheritance based on experiments with pea plant
    • Heredity is the passage of genes from parents to offspring
    • Genes appear in different versions called alleles, which can be dominant or recessive
    • Law of segregation occurs during meiosis during gamete formation
    • Law of segregation states that during gamete formation, each gene separates from each other so that the resulting gametes formed will carry only one allele for each gene

    • 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
