Describe how Mendel cross-pollinated pea plants. Mendel cut away the pollen-bearing male parts and then dusted the pollen from another plant onto the flower. He called this cross-pollination, producing seeds that had two different plants as parents.
What Did Mendel's cross-pollination of pea plants proof?
Mendel's cross-pollination of pea plants proved that genes of two separate organisms are passed to their offspring.
How do pea plants cross-pollinate?
To cross-pollinate peas, pollen from the stamen of 1 plant is transferred to the stigma of another. Before the transfer, the anthers must be removed from the recipient plant to prevent self-pollination.
What did cross-pollination allow Mendel?
Since pea plants almost always self pollinate he could remove the anthers of the flowers he had selected and cross-pollinate by hand. This practice allowed him to have complete control over which plants were the parents, and the characteristics he was introducing and observing.
What happened when Mendel crossed pea plants?
Working with garden pea plants, Mendel found that crosses between parents that differed for one trait produced F1 offspring that all expressed one parent's traits. The traits that were visible in the F1 generation are referred to as dominant, and traits that disappear in the F1 generation are described as recessive.
What is the meaning of self-pollination and cross-pollination and when did Mendel use each of these and why?
Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination occurs in flowers where the stamen and carpel mature at the same time, and are positioned so that the pollen can land on the flower's stigma.

Why did all of the F1 offspring of Mendel's purple and white flowered pea cross always look like one of the two parental varieties?
Why did the F1 offspring of Mendel's classic pea cross always look like one of the two parental varieties? One phenotype was completely dominant over another. What was the most significant conclusion that Gregor Mendel drew from his experiments with pea plants?
