Some Traits in Garden Pea Plants In pea plants, the genes for seed shape, seed colour, and plant height demonstrate independent assortment. The alleles for these genes are symbolized as follows: Seed shape Seed colour Plant height R (round) >r (wrinkled) Y (yellow) y (green) T (tall) > t (short) The phenotypic ratio of a cross between YyTt pea plant and a yyTt pea plant is Select one: a. 1 yellow tall: 1 yellow short: 3 green tall: 3 green short b. 3 yellow tall: 3 yellow short: 1 green tall: 1 green short C. 3 yellow tall: 1 yellow short: 3 green tall: 1 green short d. 1 yellow tall : 1 yellow short: 1 green tall: 1 green short O O

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
