Electron microscopy has enabled the greatest advances in understanding law of inheritance. Thus, option D is correct.
Inheritance can be defined as the process by which an offspring can carry genetic information from their parent.
Gregor Mendel who first postulated laws of inheritance while doing hybridization experiment on garden pea plant.
He proposed three laws
First Law of Dominance states that In an organism, a character express in two forms or allele.
In F1-progeny the allele which is expressed is called dominant, while the other remain masked is called recessive allele.
Second Law of segregation which states the alleles do not show any mixing and both the traits are appeared in F2-generation.
Third Law of Independent Assortment states that when two pairs of characters are combined, separation of one pair of trait is independent of other pair segregation of one pair of character.
Thus, option D is correct.

Answer:
DNA Analysis
Explanation:
Mendel's law of dominance
Mendel's law of independent assortment
Mendel's law of meiosis
Answer: Mendel's law of independent assortment
Explanation:
Mendel's 2nd law of inheritance is also known as law of independent assortment of genes.
It states that each character behaves as a SEPARATE unit and is inherited INDEPENDENTLY of any other character.
Therefore, the SEPARATION of alleles from each other so that each gamete carries only one allele PERFECTLY explains Mendel's law of independent assortment
Answer:
Mendel's law of segregation
Explanation:
The car is a system that has many parts. In a system, all of the parts function together to make the system work. If one part breaks down, the rest of the system doesn’t function properly. An incorrect or missing input results in the wrong output. For example, if the car battery is dead, the engine won’t turn on, and the car won’t move.
When a pea plant with the genotype Rr is crossed with a pea plant with the genotype rr, there is a 50% probability that the offspring will have wrinkled seeds.
The genotype of the pea plant with round seeds is Rr, while the genotype of the pea plant with wrinkled seeds is rr. When these two plants are crossed, the offspring will inherit one allele from each parent. Since the genotype of the round-seeded plant has both a dominant and a recessive allele, and the genotype of the wrinkled-seeded plant has only recessive alleles, there is a 50% probability that the offspring will have wrinkled seeds.
