Question

define law of independent assortment, law of segregation and law of dominance?

do it fast......

Answer 1

during the course of diamond formation is reaching at the recessive or dominant segregate it into their comment this law is also known as law of purity of payment or law of segregation

Answer 2

Gregor Johann Mendel was a scientist who is recognized as the Father and Founder of genetics. Mendel conducted many experiments on the pea plant (Pisum sativum) between 1856 and 1863. He studied the results of the experiments and deducted many observations. Thus, laws of inheritance or Mendel’s laws of inheritance came into existence. Before learning about Mendel’s laws of inheritance, it is important to understand what the experiments performed by Mendel were.

Mendel’s Experiments on Pea Plant

Mendel after carefully study selected the pea plant for many reasons:

The pea plants were easy to grow and maintainIt has many clearly distinct and contrasting characters.The pea plant is an annual plant and so many generations of the plant can be studied in a short period of time.Peas are naturally self-pollinating but can also be cross-pollinated.

Mendel made a list of contrasting characters which he studied:

Mendel structured his experiments in a way that he would observe one pair of contrasting characters at one time. He began his experiments using purebred lines for contrasting characters.

He cross-pollinated two pure lines for contrasting characters and the resultant offsprings were called F1 generation(also called the first filial generation). The F1 generations were then self-pollinated which gave rise to the F2 generation of second filial generation.

Results of Mendel’s Experiments

Let us look at the results of Mendel’s experiments on crossing a pure tall pea plant with a pure short pea plant.

In the F1 generation, Mendel observed that all plants were tall. there were no dwarf plants.In the F2 generation, Mendel observed that 3 of the offsprings were tall whereas 1 was dwarf.Similar results were found when Mendel studied other characters.Mendel observed that in the F1 generation, the characters of only one parent appeared whereas, in the F2 generation, the characters of the other parent also appeared.The characters that appear in the F1 generation are called as dominant traits and those that appear for the first time in the F2 generation are called as recessive traits.
