Please help with my two GCSE questions.

Explain why Mendel proposed the idea of separately inherited factors that we now call genes

and explain why the importance of Mendel's discovery was not recognised untill after his death.

Thank you so so much.

[chenglorraine]

Please can someone help me? It's really urgent!

Yes, I'm sending you my answer to your e-mail. Wait a minute.

Your welcome .

You don't want us to see the answers?

[Enzyme]

He he he :D:D Of course that I want you to see the answers . But at that time I was with my e-mail account opened and I decided to write an e-mail. That was the reason.

Here is my answer:

Mendel proposed the idea of separately inherited factors due to the quantitative results which he had in his experiments with Pisum sativum (here you have to review your notes. Try to find). Mendel concluded:

- Inheritance is transmited by particulated (separated) elements. Therefore, he refused the inheritance of mixes. [But remember, Mendel didn't introduced the name of 'genes'. This term was proposed by Johannsen in 1909].

- These results follow easy statistic standards, sumed up in his Laws.

The importance of Mendel's discovery was not recognised many time untill after his death because at that time, the new discoveries (against recent theories of that period) weren't well-seen and Mendel's experiments were refused. Due to this scepticism, Mendel talked with Carl Nägeli (an important Botanic of the period and a Mendel's friend) and this man didn't get impressed with Mendel's research and told him to research with another plants and topics. Then, Mendel's experiments and results fell in oblivion.

But in the beginnings of twentieth century, with the new advances in science, Genetics started to mature as an important science. And three scientists (Carl Correns, Hugo DeVries and Eric von Tschermak) recover the Mendel's research.

Good answer, I was curious about it. Thanks for letting us know.

PS: I asked for the answer because as this is a forum, people may have similar questions and instead of asking it again and again, they can have a search and find. Hope you don't mind.

[Enzyme]

I don't mind, he he. I like a lot Genetics and if I can help to answer people's doubts, I'll do it .

Also I have my doubts, which I letter in this forum (I'm working hard with telomerase information and I'm fighting with it :D:D:D). So you have to excuse me for not writing my answer to chenglorraine's question in the forum before .

Nice to talk with you, he he .

[Poison]

Nice to talk to you too. We like educated people here.

[Enzyme]

He he he, I see .

Now I'm going to continue looking for some information about telomerase . Ah, I forgot, happy new year if I don't cyber-see you today! .
