Mendel drew several key conclusions based on his observations of pea plants. Which of the following best describes one of his conclusions?A. An offspring that inherits different versions of the factor for a trait will not survive.B. Hereditary factors blend together to produce the traits of offspring.C. A parent can pass on two versions of the factor for each trait.D. There are at least two versions of the hereditary factors for each trait.

Mendel performed a experiment on a pea plant and took 7 main contrasting traits in the plants. Then, he performed both the experiments to determine the inheritance laws. There are at least two versions of the hereditary factors for each trait. Thus the correct option is D.

What is monohybrid cross?

Mendel performed monohybrid cross took two pea plants of opposite traits (one short and one tall) and crossed them to each other. He saw the first generation offspring were tall and called it F1 progeny. Then he crossed F1 progeny and obtained both tall and short plants (ratio 3:1). Monohybrid cross is tell the inheritance of one gene.

During gametogenesis when the chromosomes number are halved, there will be 50% chance of one of the two alleles to join with the allele of the gamete of the other parent.
