Question

Why did Gregor Mendel perform thousands of crosses between the same two plants, essentially running the same experiment over and over?

a. He wanted to be sure that his parental plants were true breeding.

b. He had difficulty keeping track of his plants.

c. The more crosses he did, the more mathematically accurate his results would be.

d. He wanted to be sure that he had attained all possible results

Answer 1

C.

Answer 2

I agree with everyone, C is the best answer

Answer 3

The answer is C. The more crosses he did, the more mathematically accurate his results would be.

This is something related to statistic. The bigger the sample size, the better in convincing other to believe him. If 3 people tell you one thing, you may doubt him, when a thousand or more people tell you the same thing, you are more likely to believe him.

Other answer

A. Could be right but compair to answer C, I wouldn't choose answer A

B. I don't think so, it wasn't that difficult to keep track of those plants.

D. It could be true, but not in this experiment. Gregor Mendel knows there won't be too many possible outcomes even before his experiment.

Answer 4

c

Answer 5

I would have to agree with Donna on this.  The more crosses he did, the more mathematically accurate his results would be.  Mendel suspected that heredity depended on contributions from both parents and that specific characteristics from each parent were passed on, rather than being blended together in the offspring.  Mendel derived certain basic laws of heredity: hereditary factors do not combine, but are passed intact; each member of the parental generation transmits only half of its hereditary factors to each offspring (with certain factors "dominant" over others); and different offspring of the same parents receive different sets of hereditary factors. Mendel's work became the foundation for modern genetics.
