Detailed explanation-1: -Mendel found that paired pea traits were either dominant or recessive. When pure-bred parent plants were cross-bred, dominant traits were always seen in the progeny, whereas recessive traits were hidden until the first-generation (F1) hybrid plants were left to self-pollinate.

Detailed explanation-2: -In his monastery garden, Mendel performed thousands of crosses with pea plants, discovering how characteristics are passed down from one generation to the next-namely, dominant and recessive traits. Mendel’s early experiments provided the basis of modern genetics.

Detailed explanation-3: -Our modern understanding of how traits may be inherited through generations comes from the principles proposed by Gregor Mendel in 1865.

Detailed explanation-4: -Mendel’s law of dominance states that in a heterozygote, one trait will conceal the presence of another trait for the same characteristic. Rather than both alleles contributing to a phenotype, the dominant allele will be expressed exclusively.
