Mendel was successful In discovering the principles of inheritance as __________________.
He chose garden pea that was easy to grow and to hybridise artificailly.
The plant reproduce well and grows to maturity in a single season.
Mendel then chose to follow seven visible features(unit characters), each represented by two contrasting forms or traits.
Mendel was fortunate in choosing a diploid plant because diploid organisms contain only two sets of chromosomes.
A singe alteration in a trait was therefore demonstrated by a visible differences between varieites.
He restricted his examination to one or very few pairs of contrasting traits in each experiment.
He also kept accurate quatitative records, a necessity in genetic experiments.
In his experiments, no appearance of recombinations and linkage.
So, the correct option is ‘He did not encounter the linkage’.
