Question

Having white flowers is a recessive trait. a plant with white flowers is crossed with a plant that is heterozygous for purple flowers. Draw a Punnett square to show the possible genotypes of their offspring. Then list the proportion of each expected phenotype in the offspring. b. A researcher carries out the above cross and then counts the phenotype of the offspring. Of the offspring 70 had purple flowers and 30 had white flowers. Perform a Chi-square to test whether the observe counts fit with the expected frequencies calculated above. c. Write a statement of results for your Chi-square and interpret its meaning.
