Why was Gregor Mendel able to form accurate conclusions about offspring phenotypes?

Question

Could you help me please I need two reasons.

Even when his actual results were slightly different from predicted results?

Answer 1

Hi. One reason was his choice to use seven characteristics.

Answer 2

He limited his studies to the 7 specific characters which came in two distinct forms. He basicaly looked at one thing at a time.

Second, he kept very careful records of the numbers of each type of offspring produced from each of his crosses. People before him didn't actually count the exact numbers of different offspring like Mendel did.

Answer 3

*laughs* He probably fudged his data a little. Don't tell your teacher I said that.

1. He chose a plant that was easy to grow, breed, and study; one for which the pollination could easily be controlled artificially.
2. He chose characteristics to observe that were easy to observe!
3. He chose characteristics to observe for which dominant and recessive were very distinct from each other, and which showed only dominant and recessive phenotypes (no mixing -- no "midway between wrinkled and round" or "midway between tall and short.")
4. He got lucky, and chose characteristics which independently assorted from each other -- that is, they weren't linked by being on the same chromosome as some other characteristic he was observing.
