Question about Mendel's experiment

Post by taki » Sun Feb 26, 2006 5:27 am

Relate why Mendel began his experiments by allowing pea plants to self-pollinate for several generations.

My answer so far is that Mendel wanted to find out an explanation for variations in height. (tall plants grew from seeds obtained from tall plants and short plants grew from some of the seeds from tall plants). However, I'm still unsure.

Thank you for any help~

to ensure that all the offsprings are homozygous??

no...mendel could care less about homozygosity; he was more interested in seeing the patterns of inheritance

Mendel didn't know about how our inheritance system is...he wanted to find it out...as mithril said.

well, my guess is just he is just carrying out cross breeding of different varieties of peas perhaps just for the fun of it.
then, perhaps he noticed some ratio in the results and therefore came up with the dominant-recessive theory and set out to test it.
and of course u will need a purebreed(homozygous) in this experiment..

Mendel noticed differences in flower color on pea plants, and he wanted to study the inheritance patterns of them. That's how he designed his experiment (he had classical training in physics, so he knew how to adhere to the scientific method). Based on the results of his experiments, he calculated frequencies and that's what led to the inheritance patterns that we understand today.
