they showed the scentific properties of inheritance.
in one of his experiments, he took 2 pea plants and breeded them. Their offspring had some similarities in appreance with the parent plants. These similarities later were called genetics.

The 'father of genetics' , Gregor johann mendel started working on the problem of how the variations were passed from one generation to the other in his monastery garden .
From the experiments , he hypothesized that characters were carried as traits and an organism always carried a pair of factors for a character were present in the population.
example:
Consider his experiment with two reeds of peas which had peas of seed color contrasting the characters yellow and green , and they are represented as yellow with 'Y' and green with 'y'. He started cross fertilising pure breeds having contrasting characters.
We here take as an example a characteristic color of pea seeds yellow and green.
CROSS POLLINATING A PURE BREED OF YELLOW AND GREEN GAVE
FIRST FILIAL (F1) GENERATION-ALL SEEDS ARE YELLOW
SECOND FILIAL(F2) GENERATION- HERE ABOT 25% OF THE SEEDS ARE GREEN AND 75% OF THE SEEDS ARE YELLOW-THEY CROSS FERTILISE TO GIVE
THIRD FILIAL (F3) GENERATION
. A set of peas gave only yellow seed giving plants.
.Rest of the yellow seed giving plants gave bout 75% yellow and about 25% of green seed giving plants.
.The set of green peas gave only green seed giving plants.
HE found
.every pea plant has two factors which are responsible for producing particular character or trait .
the determining agent is responsible for each trait is called a 'factor'.
.during reproduction one factor from each parent is taken to form progeny
one of these will always dominate the other if mixed together.
