Question

How do Mendel experiment show that traits may be dominant and recessive?

Answer 1

when Mendel took two pure line tall and short pea plants and cross bred them only one characteristic that is tall was expressed in F1 generation . this showed that tall characteristic is dominant and the other characteristic that is short, failed to express itself in F1 generation but reappeared in F2 generation is called recessive trait

Answer 2

|$\large\mathrm\purple{Solution}$|

According to law of dominance, an attribute is painted by 2 contrastive factors of a factor during a heterozygous individual; the allele/factor that may specific itself in heterozygous individual is named as dominant trait. The opposite issue whose impact is cloaked by presence of dominant factor, is named recessive issue. Once Johann Mendel crossed one tall and one short leguminous plant, all the off springs (F1 generation) were tall. Once he self-crossed the F1 generation, among them 3/4th of the progenies were tall whereas 1/4th were short. So he ended that though the F1 relation had each tall and short traits, solely tall plants were discovered within the F1 generation, this implies that tallness may be a dominant attribute.
