Subsequently, in each of his experiments, Mendel noticed a pattern of traits and inheritance. True-breeding plants exhibit stable inheritance of traits. Mendel made sure to use only true-breeding plants in his experiments. Which of these is a trait Mendel studied in the pea plant? How well have you learnt about Mendel’s experiments? Test yourself with this quiz. These were the characteristics that he studied. Pea plants have a set of 7 distinct character traits.Īfter that, Mendel began to observe a pair of contrasting traits at a time, and he experimented using true-breeding pea plants. Thus, many generations of this plant can be examined in a very short span of time. He picked out the pea plant due to the following reasons: Gregor Mendel now decided to analyse the patterns of inheritance in the pea plant. Then write what you learn in your notebook.

The capital A stands for the dominant trait while the lowercase a stands for the recessive trait. Thus, he theorised that genes or these factors could be paired in three combinations: AA, Aa and aa. Mendel then self-fertilised the F1 generation, and in the F2 generation, he observed that the flowers showed phenotypes in the ratio 3:1. Moreover, Mendel stated that these factors, which we now call genes, always occur in pairs. Of these, one was recessive and the other dominant. He then deduced the idea of "factors" or hereditary units. To his astonishment, he discovered that the product was a purple flower instead of a combination of two colours. Mendel crossed a true-breeding white flower and a purple flower plant. Read on to learn more about the Gregor Johann Mendel experiment. Mendel described these two laws in a paper called "Experiments on Plant Hybridization", published in 1866. These are now called Mendel's Laws of Inheritance or Mendelian Inheritance. From his observations, he deduced two theories. From 1856 up till 1863, Gregor Mendel tested 28,000 pea plants. Gregor Mendel was a 19 th -century Augustinian monk and the humble founder of genetics. Mendelian genetics is the study of the physical traits of individuals. The field of science that examines how genes and genetic traits are inherited from one generation to the other is known as genetics.
