Textbook Question
Chapter 2, Problem 3P
Describe the characteristics of the garden pea that made it a good organism for Mendel’s analysis of the basic principles of inheritance. Evaluate how easy or difficult it would be to make a similar study of inheritance in humans by considering the same attributes you described for the pea.

- Why was Mendel’s success dependent on his studying characteristics that exhibit only two easily distinguished phenotypes, such as white versus gray seed coats and round versus wrinkled seeds? Would he have been less successful if he had instead studied traits such as seed weight or leaf length, which vary much more in their phenotype?arrow_forwardUsing Mendel’s lines of peas, describe how you would use a test cross experimental design to determine the genotype of a pea plant with purple flowers. Be very specific in describing your experimental design and how you would interpret your results based on the proportion of offspring phenotypes. Make sure to include all possible offspring phenotypes in your answer and what the proportion of phenotypes tells you about the purple plant genotype.arrow_forwardWhy was Mendel’s success dependent on his studying characteristics that exhibit only two easily distinguished phenotypes, such as white versus gray seed coats and round versus wrinkled seeds?
