Gregor Mendel conducted hybridisation experiments on garden pea plants during the period ______.

The correct option is A 1856 - 1863

Gregor Mendel worked during the mid-nineteenth century and made a breakthrough in the concept of inheritance.

He conducted hybridisation experiments on Pisum sativum (garden pea) for a period of seven years between 1856-1863 and proposed laws of inheritance that units called ‘factors’ are being passed from parent to offspring.

Mendel conducted such artificial pollination/cross-pollination experiments using several true-breeding pea lines.
