Dara points out two different plants that both have significantly more leaves than the wild-type plants and calls these plants "leafy". Wild-type Leafy Dara wants to test if the two leafy plants have mutations in the same gene that causes the leafy phenotype. You breed both leafy plants until you are confident that you have created two separate true-breeding leafy strains. Hypotheses for Leafy Gene 1.0/1.0 point (graded) To test if the leafy plants have mutations in the same gene, you fertilize a true-breeding leafy plant from one strain with pollen from a true-breeding leafy plant from the other strain. The F1 offspring from this cross are all leafy. One possible hypothesis is that the parent plants have mutations in different leafy genes that both result in dominant phenotypes. Which of the following alternative hypotheses could this result support instead? Select all that apply. The parents have mutations in the same leafy gene. The parents have mutations in different leafy genes that both result in recessive phenotypes. The parents have mutations in different leafy genes, but one mutation results in a dominant phenotype, and the other mutation results in a recessive phenotype. Submit You have used 1 of 1 attempt Show answer Leafy Genes: Map Distance 0.0/1.0 point (graded) You perform a series of crosses with the leafy plants, and the results support your original hypothesis: the parent plants have mutations in different leafy genes that both result in dominant phenotypes. Next, you cross an F1 leafy plant to a wild-type plant. You plant the seeds from this cross and observe the following phenotypes for the resulting plants. Cross Results # of Offspring Phenotypes leafy regular leaves 87 1 What is the map distance including standard deviation for the leafy gene(s)? Assume that recombination follows a Poisson distribution and that not all leafy progeny are parental. Enter your answer as numbers with three significant figures each. +/- Submit You have used 1 of 2 attempts CM Save Leafy Gene Size 0.0/1.0 point (graded) The recombination frequency rate in Arabidopsis is 4.25 CM/Mbp. For it to be possible that the two leafy plant strains have mutations in the same gene, what minimum length would this leafy gene need to be in Mbps (megabase pairs)? Enter your answer as a number with two significant figures. Mbps
