What is the basis of heredity?
Inheritence
What is inheritance?
Process by which characters are passed from parent to progeny
What is Progeny?
Offsprings
What is degree by which progeny differ from their parents?
Variation
Mendel experimented on —– for seven years
Pisum Sativum (Garden Pea plant)
Removal of Anther
Emasculation
Transfer of Pollen
POllination
F1
filial generation
In F1 generation, all pea plants were
tall
What happened in F1?
Mendel observed that F1 always resembled either one of the parents and that the trait of other parent was not seen in them
What did mendel do next after F1?
He self pollinated the tall F1 plants
What did he do after self pollinating f1 plants?
In F2, some offsprings were dwarf. The character that was not seen in F1 was now expressed
Proportion of dwarf in F2 generation
1:4
Conclusion OF F2
The tall and dwarf traits were identical to their parental type and did not show any blending i.e none of them were in between height
