Marigolds are a common garden plant (n = 16) of great interest to breeders, and they can be found in both diploid and autotetraploid forms. Autotetraploid marigold plants are fertile, and in meiosis their chromosomes pair only as bivalents. One locus of particular interest to breeders controls flower color, where Y = yellow and y = white, and is found close to the centromere on chromosome 3. Another controls the height of the plant, where M = normal height and m = miniature, and is closely linked to the centromere on chromosome 11. Both Y and M are fully dominant over y and m. a. (5 points) In the lab, you use cytogenetic techniques to observe meiosis in tetraploid marigolds. What is the total number of bivalents that you will expect to see during meiosis I? After meiosis is complete, how many chromosomes will be present in the gametes? Explain your answer for each. b. (10 points) In the field, you carry out some breeding experiments on your tetraploid marigolds. If you self-fertilize a tetraploid plant that has the genotype Y//y/y; M/M/M/M, and then look at the resulting progeny, what proportion will be normal height with white flowers? Explain your answer and show your work. points) If instead you allow a tetraploid marigold with the genotype Yly/y/y; M/M/M/M to self-fertilize, what proportion of the progeny will have white flowers and normal height? Explain your answer and show your work. c
