Answer 1

Dear Student

Gregor Johann Mendel (1822 – 1884) was the first to carryout the study on the transmission of characteristics from the parents to the offsprings. He proposed that heredity is controlled by factors, which are now believed to be segments of chromosomes or genes.

Mendel performed experiments on a garden pea (Pisum sativum) with different visible contrasting characters. He selected seven contrasting pairs of characters or traits in a garden pea. These include round/wrinkled seeds, tall/short plants, green/yellow pod colour, purple/white flower colour, axial/terminal flower, green/yellow pod colour, and inflated/pinched ripe pods.
