Question

When Gregor Mendel experimented on pea plants, he would cross-pollinate them. This led to the discovery of what later would be the Mendelian laws of genetics. To cross-pollinate, he would remove the male parts of one flower and dust it with the pollen of another. What was his purpose of doing so?

Answer 1

Answer :

Mendal studied inheritance in Pisum Sativum.

Pea flowers contain both male and female parts.

Called stamen and stigma.

Self pollination happens before fowers open. Self pollination is between stamen and stigma of same flower.

In cross pollination he need pollen from stamen of another plant to fertilize stigma of other one.

So self pollination should be prevented. Otherwise cross pollination wont be pure.

So stamen of flower of interest is removed by opening the bud. Then pollen from desired flower is dusted on to stigma.

Simply he removed stamen to prevent self fertilization.
