Question

It is common to study the biology and genetics of bacteria, yeast, fruit flies, and mice to understand biological and genetic processes in humans. Why do you think this is the case?

Accepted Answer

Hello, everyone. Here's our next question. Which of the following model organisms was primarily used by Mendel to investigate the patterns of inheritance. And we have choice. A pea plant choice be fruit fly, choice C yeast and choice D zebrafish. Well, all these organisms are used in genetic research today, but hopefully, we recall that Mendel used pea plant in his famous experience experiments. So choice. A pea plant is our answer here. P plants have a very rapid lifecycle and produce many seeds. They also readily self pollinate, which makes it easy to establish true breeding lines of different traits and yet they're also easy to cross pollinate. So once you've got your true breeding lines with different traits, it's fairly easy to cross those lines and see what the results are. So that's why these were ideal organisms for Mandela study genetics. Um And of course, he studied different traits, flower color, seed, color, seed shape. Um He did get very lucky because the traits he studied happened to be on different chromosomes which allowed him to formulate the law of independent assortment. Had he picked, say jeans that were closely linked on the same chromosome that might not have been so straightforward for him. So again, which model organism primarily used by Mendel choice? A the pea plant? That was a nice easy one for us. I hope to see you in the next video.
