Answer 1

Ello user !!!!!!!

Here is your answer,

========================================

Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance.

He deduced that genes come in pairs and are inherited as distinct units, one from each parent.

Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.

Answer 2

$\huge\mathscr{Your \:Answer:-}$

Mendel developed three principles of inheritance based on his experiment with pea plant. He selected seven varieties of garden pea plants differing in seven pairs of contrasting characters.

๏ $\bold{Law\:of \:Dominance}$ – In a cross of parents that are pure for contrasting traits, only one form of the trait will express in the next generation.

๏ $\bold{Law\:of\:segregation}$ - The two members of a gene pair segregate or separate from each other at the time of gamete formation.

๏ $\bold{Law\:of\:independent \:assortment}$ – Genes for different traits assort independently from one another at the time of gamete formation.

These three principles have cleared our concept regarding inheritance of characteristics from parents to offspring. If the Law of Segregation did not exist then in each successive generation the number of genes would have been doubled than the earlier. Similarly, if the law of independent assortment did not happen, all the genes would have been locked with each other and not a single gene can be able to express independently.
