Referring to the passage, tell why it was important that Gregor Mendel used a large number of plants in his experiments into genetics and heredity?
Gregor Mendel used pea plants to conduct experiments on genetics and heredity. He grew approximately 29,000 plants to study seven characteristics: flower color, seed texture, seed color, stem length, pod color, pod texture, and flower position. Mendel was able to demonstrate that these characteristics were passed from one generation to the next and that the offspring could inherit the characteristics from either one, or from both, of the parent plants.
CorrectIncorrect - Question 55 of 65
55. Question
Referring to this passage, what could Gregor Mendel conclude from the result of his experiment with green and yellow pea plants?
Pea plants can self-pollinate (sperm and eggs both come from the same plant) or they can cross-pollinate (sperm and eggs come from different plants). Gregor Mendel used this to study heredity. He found that if he took a plant that only produced yellow peas and crossed it with a plant that only produced green peas, all the offspring would only produce yellow peas.
On the other hand, if he left the offspring (all yellow pea plants) alone and let them self-pollinate, then the second generation had a ratio of 3:1 yellow to green pea plants. Thus, Mendel could demonstrate that some traits are “dominant” while others are “recessive.”
