Which of the following traits studied by Mendel in garden pea is a dominant trait?
Mendel conducted experiments on garden pea plants to identify the inheritable traits, patterns of hybridisations between what he called as 'factors'. He selected seven pairs of contrasting characters out of which he found the inflated pod is one of the dominant traits.
He observed that even though the offspring receives a set of chromosomes (one from each parent) for each trait, out of differing traits, only one trait from that set gets expressed in the phenotype (physical appearance) of the offspring. Such a trait is called dominant whereas the other one that does not get expressed is called recessive. For example, flower positions have two alternate forms - terminal and axial where the axial is the dominant trait and the terminal is recessive.
Similarly, flower colors have two alternates: Violet and white flowers where violet flower color is dominant over white.
