Question

Mendel’s last law is
A) Dominance
B) Segregation
C) Polygenic inheritance
D) Independent assortment

Answer 1

Hint: Gregor Johann Mendel (1822-1884) developed the law of independent assortment. This is also referred to as the Mendel law of inheritance. This leads to the foundation of the massive history of human Genetics.

Complete answer:
Gregor Mendel is the father of genetics. Mendel conducted experiments on the pea plants and observed their pattern of inheritance from one generation to the next generation. His investigation led to the discovery of three laws: Law of Dominance, the law of segregation, and the Law of independent assortment.

Now let us analyze the given options:
A) DOMINANCE: Law of Dominance is known as the first law of inheritance. If the two alleles differ then one, the dominant allele determines the organism appearance and the recessive allele has no noticeable effect on the appearance of the organism.
B)SEGREGATION: Law of segregation is known as the second law of inheritance. The two alleles for a heritable character separate ( segregate)during gamete formation and end up in different gametes.
C) POLYGENIC INHERITANCE: When one phenotypic character is controlled by more than one gene, it is called polygenic inheritance.Kolerenter is the father of polygenic inheritance
D) INDEPENDENT ASSORTMENT: This is Mendel last law of inheritance. Each pair of alleles segregates independently of other pairs of alleles during the gamete formation.

Thus , the correct answer is option ‘D’ i.e, INDEPENDENT ASSORTMENT.

Note: The rule of inheritance is referred to as Gregor Mendel laws. The Mendel law is applicable to all the living organisms that sexually reproduce. Mendel studied the inheritance of seven different pairs of contrasting characters in garden pea plants such as stem length, flower position, pod shape, pod colour, seed shape, seed colour, seed coat colour and conducted a breeding experiment dealing with a single character called a monohybrid cross.
