CONTINUATION FOR QUESTION #218928

Compose a response to the following questions. Explain your answer using, and fully explaining, the genetic terms and concepts using the Mendel's experiment. Use headers to label each part of your experiment and/or use sentences to introduce each section.  

Form a conclusion: Were the results close to the expected 9:3:3:1 phenotypic ratio? Do the results support the prediction? What might be observed if far fewer plants were used, given that alleles segregate randomly into gametes? Try to imagine growing that many pea plants, and consider the potential for experimental error. For instance, what would happen if it was extremely windy one day? 

Answer 1

Mendel crossed pure lines of pea plants. Dominant traits, like purple flower colour, appeared in the first-generation hybrids (F1), whereas recessive traits, like white flower colour, were masked. However, recessive traits reappeared in second-generation (F2) pea plants in a ratio of 3:1 (dominant to recessive).
