What led to scientists accepting mendel's ideas?

Gregor Mendel was the first biologist who applied the principles of mathematics to study the pattern of inheritance in Biology. This led to the criticism and not an acceptance of his work at his time but after his death, his work was widely recognised as:

1. Mendel's work provided each and every detail of the experiment from species to a number of offsprings and traits.

2. His experiments included a large sample size which reduced the chances of error in his results.

3. He studied the pattern of inheritance for distinguishing traits.

4. His ideas and explanation on experiments were logical which were supported by the scientists later.

These logical ideas later helped recognize his work and he became the Father of Genetics.
