So just what are they? Aa Aa Aa. Ever wonder why you are the only one in your family with your grandfather's nose? The way in which traits are passed from one generation to the next-and sometimes skip generations-was first explained by Gregor Mendel. By experimenting with pea plant breeding, Mendel developed three principles of inheritance that described the transmission of genetic traits, before anyone knew genes existed.

Mendel's insight greatly expanded the understanding of genetic inheritance, and led to the development of new experimental methods. Figure 1. The couple has one female offspring, who is not affected with WS.

The couple has a single male offspring generation 3 who is not affected with the disease. This male offspring mates with a female unaffected with WS, and the couple has a single male offspring generation 4 , unaffected with the disease. The couple has five children generation 3 , identified as individuals 8, 9, 11, 13, and Three of the offspring are male, and two are female.

Individual 8 a male is affected with WS and mates with a female that is not affected with WS. The couple has three offspring: two females that are affected with WS and one male that is not affected by the disease. Individual 9 a male is not affected with WS and mates with a female that is also not affected with WS. The couple has two female offspring, neither of whom are affected with WS.

Individual 11 a female is not affected with WS and mates with a male that is also not affected with WS. The couple has three male offspring, none of whom are affected with the disease.

Individual 13 a male is affected with WS and does not reproduce. Individual 14 a female is not affected with WS and mates with a male that is also not affected with WS. The couple has two female offspring, both of whom are not affected with the disease. Figure 3. Understanding Dominant Traits. Understanding Recessive Traits. Figure 4. Figure Detail.

Widely regarded as the father of modern genetics, Moravian friar Gregor Mendel was the first to discover that inherited traits do not blend, but remain intact through generations.

However, Austrian monk Gregor Mendel was unconvinced with traditional explanations of how traits were passed from one generation to another. Between and , Mendel decided to try and work out the principles of heredity himself, with the assistance of the humble garden pea Pisum sativum L. Among the many species on which Mendel worked, he selected pea because the plants and seeds have a wide array of distinct features that occur in two easily identifiable forms e.

The pea flower is another useful feature of these plants , as it ensures that the flowers of the hybridised and parent plants are protected from any foreign pollen.
