introducing

By Shivendra Kumar

1. Principle of genetics introducing Mendelian genetics.

2. Shivendra kumar m.Sc (agricultural biotechnology) All M endelian genetics including M endel research work

3. Where mendel publish the research paper? In 1866 publish research paper entitiled “ Versuche über Plflanzenhybriden. Verhandlungen des naturforschenden Vereine s „in Germen . which means“ Experiment on Plant hybridization” . Result of his experiment where published in the science journal,”Nature For schender varien”in 1866. Journal was published by Natural History society of Brunn .

4. 1.Father of genetics . 2.worked on garden pea . 3.take 7 contrast character. 4.place of born – moravia ( austria ). 5.in 1862 become one of the founder member of natural history science society. 6.in 1865 gave first two lectures on his pea experiment in brunn natural science society. 1 Gregor johann Mendel (22 nd july 1822-1884)

5. Contd ……

6. How he describe his result? By Interactive pea plant experiment  Interactive pea experiment where you can breed your own hybrid pea plants!  Mendel came to three important conclusions from these experimental results:  1.That the inheritance of each trait is determined by "units" or "factors" (now called genes) that are passed on to descendents unchanged  . 2.That an individual inherits one such unit from each parent for each trait  3.That a trait may not show up in an individual but can still be passed on to the next generation. 

7. Contd …. By establishing 2 law’s 1.law of segregation. 2.law of independent assortment.

8. Mendel finding characters /crop. He take seven contrasting character . He said that seven character are present on 4 chromosome only but that will not true ,instead of this 7 character on 14 chromosome . Working on Garden pea. s.n characters Contrasting traits 1 Stem height Tall/dwarf 2 Flower colour Violet/white 3 Flower position a xial/terminal 4 Pod shape Inflated/constricted 5 Pod colour Green/yellow 6 Seed shape Round/wrinkled 7 Seed colour Yellow/green

9. Any other scientist to try to study genetics like mendal on which character!

10. Reason of success of mendal experiment! He studied the inheritence of one or two character at a time(contrasting character ). Selection of short duration plant. Natural self pollination is present in pea plant so purity of character is maintained. It has many contrasting traits. For hybridization ,cross pollination is to be possible. Mendel quantitatively analyse the inheritance of qualitative characters. He has to maintained the statistical records of all the Experiment.

11. How M endal work? By applying emasculation and bagging for hybridization in plants.

12. Contd …

13. What happens if , Mendal was not born? Then we will aware about genetics so late. And father of genetics will be karl correns / teshmark / hugo de varies. We will escape from statistical data of his experiments.
