The Characteristics of the pea plant studied by Mendel are also called as traits. The observable traits expressed by an organism are referred to as its phenotype. Why did Mendel select pea plant for his experiments? Purple flower : White flower. Through breeding of multiple generations of pea plants, Mendel discovered that purple flowers are dominant and white flowers are recessive. True-breeding pea plants showing contrasting character for flower position were cross-bred. Yellow seed : Green Seed. For cross pollination, garden pea, being self fertilizing plant, anthers have to be removed before maturity. 2.

Mendel focused on the different traits, or characters, that he noticed pea plants exhibiting in a binary manner. The hybrids of the pea plants produced by cross-pollination are perfectly fertile. In his study, Mendel proposed that genetic traits are dominant and recessive and that they can skip generations. In the mid- to late 19th century, scientists struggled to understand fully the specifics of genetics. Question 2. To fully examine each characteristic, Mendel generated large numbers of F 1 and F 2 plants and reported results from thousands of F 2 plants. The Principle of Segregation proposed by Mendel stipulates that each parent has two alleles, or genetic encoders, for each trait, and that one of these alleles passes from each parent to offspring. a.
