How did Mendel control the reproduction of pea plant?

Assalamualaikum n hi !

Just want to share something that I've found from the internet.

you can click on the picture to make it larger :)

This is about the question yang pernah keluar for my mid semester examination. I've google it so many times. But, what I've found is about the crossing part. This is actually that I wanna know. And, Alhamdulillah finally I've found it.

So, how did Mendel control the reproduction of the pea plant?

In pea plant, the female and male sexual organs are in the same flower. So, it can undergoes self-fertilisation. So, in order to avoid self-fertilisation of the pea plant, Mendel removed the stamens from flower bud before their anthers produced any mature pollen.

(I just rewrite the things in the picture above)

***  The main methods that Mendel used are cross-fertilisation (hybridisation) and artificial fertilisation. To prevent self-fertilisation, Mendel remove the anthers from the female parents before the plants produce mature pollen. He then transfer the pollen with a paintbrush from the anthers of the male parent to the stigma of the female parent. (this is hoe Mendel control the fertilisation in the pea plants. And this is the answer for the Mid Semester Question)

I've found this information here.

It's actually an animation. It's fun to watch and easily to understand.
