Answer:
Mendel’s laws
The two experiments lead to the formulation of Mendel’s laws known as laws of inheritance which are:
- Law of Dominance
- Law of Segregation
- Law of Independent Assortment
Law of Dominance
This is also called Mendel’s first law of inheritance. According to the law of dominance, hybrid offsprings will only inherit the dominant trait in the phenotype. The alleles that are suppressed are called as the recessive traits while the alleles that determine the trait are known as the dormant traits.
Law of Segregation
The law of segregation states that during the production of gametes, two copies of each hereditary factor segregate so that offspring acquire one factor from each parent. In other words, allele (alternative form of the gene) pairs segregate during the formation of gamete and re-unite randomly during fertilization. This is also known as Mendel’s third law of inheritance.
Law of Independent Assortment
Also known as Mendel’s second law of inheritance, the law of independent assortment states that a pair of trait segregates independently of another pair during gamete formation. As the individual heredity factors assort independently, different traits get equal opportunity to occur together.
Key Points on Mendel’s Laws
The law of inheritance was proposed by Gregor Mendel after conducting experiments on pea plants for seven years.
The Mendel’s laws of inheritance include law of dominance, law of segregation and law of independent assortment.
The law of segregation states that every individual possesses two alleles and only one allele is passed on to the offspring.
The law of independent assortment states that the inheritance of one pair of genes is independent of inheritance of another pair.
