Question

Which of the following is not considered as a law?
(A)Law of dominance
(B)Law of independent assortment
(C)Law of segregation
(D)None of the above

Answer 1

Hint: Gregor Mendel, after performing his experiments on pea plants, discovered the fundamental laws of inheritance. He proposed three laws of inheritance which we are studying to date. Those laws were very beneficial for us to study about genetics.

Complete answer:
He recognized the mathematical patterns of inheritance from one generation to subsequent. Mendel's Laws of Heredity are usually stated as:
- The Law of Segregation: As we all know that each inherited trait is defined by a gene pair. Parental genes are randomly separated into the sex cells in order that sex cells contain just one gene of the pair. Offspring, therefore, has only one genetic allele from each parent when sex cells unite during fertilization.
- The Law of Independent Assortment: According to this law, genes for various traits are sorted separately from each other so the inheritance of 1 trait isn't dependent on the inheritance of another.
- The Law of Dominance: When an organism contains alternate pairs of a gene then the dominant form of its gene will get expressed.
The conclusions which were depicted by Mendel's experiment are:-
- The genetic makeup of the plant is understood as the genotype. On the contrary, the physical appearance of the plant is understood as phenotype.
-The genes are transferred from parents to the offspring in pairs referred to as alleles.
-During gametogenesis when the chromosomes are halved, there's a 50% chance of 1 of the 2 alleles to fuse with the opposite parent.
-When the alleles are identical, they're referred to as homozygous alleles and when the alleles are different they're referred to as heterozygous alleles.
So, the correct answer is ‘None of the above’.

Note: It is very interesting to note that the experiments which Mendel did with pea plants took him eight years i,e from 1856-1863, and he published his results in 1865. During this time, Mendel grew a large number of around 10,000 pea plants where he studied the number of their progenies and types.
