Solved in 3 steps
- How did Mendel know that each of his pea plants carried two alleles encoding a characteristicExplain how Mendel’s interpretation of his pea plant experiments would have changed if he did not use pure breeding, homozygous genotypes in his P1 generation, but instead used heterozygotes.explain how the model using coin tosses in the activity "gene combo" compare mendel's explanation for his results with pea plants
- 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 like seed weight or length of the leaves, which vary much more in their phenotypes? Explain your answer.What advantages were provided by Mendel’s choice of the garden pea in his experiments?Explain how Mendel’s laws apply to multifactorial traits.
- Mendel describes subjecting each of the 34 varieties of peas he obtained to a two-year trial. During this time he let the plants self-fertilize and observed their offspring. What was he looking for, and what was the purpose of doing this two-year trial? Explain what Mendel means when he writes that the 3:1 ratio observed in the first generation from the hybrids "resolves itself" into a ratio of 2:1:1Why 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 phenotypes? Explain your answer.explain the important features of Mendel’s experimental design?
