What is Mendelism
Mendel was a monk in Austria.
Mendel performed a number of experiments on the gardan pea plants (Pisum sativum).
Mendel’s Law :
The theoretical explanation of mendel’s results are now firmly establisas Mendel’s laws of inheritance.
These are as follows :
Mendel’s law of Dominance :
According to this law, if a cross is made between plants with contrasting pair of charactess, the character that appears in the first generation is dominant and the other is recessive.
Mendel’s monohybrid cross between a homozygous red flowered (RR) and a homozygous white flowered (rr) plant to show that red colour is dominant over white (recessive)
Mendel’s law of segregation (or law of purity of gametes) :
Both parental allels (i.e. dominant as well as recessive) segregate or separate and are expressed phenotypically in F2 generation, and this is called mendel’s Law of segregation.
Mendel’s Law of Independent Assortment :
Which states that most of the characters of parents can appear in any combination in their offsprings
