Around 1857, Gregor Mendel began breeding green peas to study inheritance. Although heredity was still unknown at the time, Mendel was curious about the subject. Mendel worked with green peas because they were simple to test, produced large numbers of offspring, and had different variety of traits. Mendel discovered that when he bred two true-breeding peas: one purple and one white (a purple flower's offspring will always turn out purple) produced offspring of purple flowers (why was it only purple and not white?) because the trait for a purple color for peas is more dominant. Then he decides to breed those new purple flowers. Mendel found a 3 to 1 ratio of purple and white flowers. This led to two laws from Mendel: the law of segregation and the law of independent assortment.He studied the effects genetics had on the colors of the flowers of a plant.
Mendel's first law (also called the law of segregation) states that during the formation of reproductive cells (gametes), pairs of hereditary factors (genes) for a specific trait separate so that offspring receive one factor from each parent. Mendel's second law (also called thelaw of independent assortment) states that chance determines which factor for a particular trait is inherited. Mendel's third law (also called the law of dominance) states that one of the factors for a pair of inherited traits will be dominant and the other recessive, unless both factors are recessive.
