Detailed explanation-1: -A trait is defined as a variation in the physical appearance of a heritable characteristic. The characteristics included plant height, seed texture, seed color, flower color, pea pod size, pea pod color, and flower position.
Detailed explanation-2: -Each gene can have several variants, called alleles, which code for different variants of the trait in question. Genes reside in a cell’s chromosomes, each of which contains many genes.
Detailed explanation-3: -A gene variant is a permanent change in the DNA sequence that makes up a gene. This type of genetic change used to be known as a gene mutation, but because changes in DNA do not always cause disease, it is thought that gene variant is a more accurate term.
Detailed explanation-4: -Offspring acquire a mix of traits from their biological parents. Different organisms vary in how they look and function because they have different inherited information. In each kind of organism there is variation in the traits themselves, and different kinds of organisms may have different versions of the trait.
Detailed explanation-5: -Flavonoid Biosynthetic Pathway. The presence or absence of these pigments affects the coloration of the floral display, which attracts pollinators. The anthocyanin pigments are therefore important to reproductive success and hence to gene transmission.
