10) Two pure-breeding phlox plants were crossed, one with dark-blue flowers and the other with pinlThe Fi generation all had dark-blue flowers. When the F₁ were crossed with each other, the F₂ generaticonsisted of 176 plants: 101 with dark-blue flowers, 33 with light-blue flowers, 30 with red flowers, arpink flowers.10) What progeny types would result from crossing pure-breeding plants with light-blue flowenbreeding plants with red flowers?A) all would be dark blueB) 1 light blue: 1 redC) 9 dark blue: 3 light blue: 3 red: 1 pinkD) all would be red

Three individual plants were collected from nature (thus not necessarily pure breeding) before flow- ering and were either crossed or self-pollinated. The results are shown below.

A corn geneticist wants to obtain a corn plant that hasthe three dominant phenotypes: anthocyanin (A), longtassels (L), and dwarf plant (D). In her collection ofpure lines, the only lines that bear these alleles are AALL dd and aa ll DD. She also has the fully recessive lineaa ll dd. She decides to intercross the first two and testcross the resulting hybrid to obtain in the progeny aplant of the desired phenotype (which would have to beAa Ll Dd in this case). She knows that the three genesare linked in the order written, that the distance between the A/a and the L/l loci is 16 m.u., and that thedistance between the L/l and the D/d loci is 24 m.u.a. Draw a diagram of the chromosomes of the parents,the hybrid, and the tester.b. Draw a diagram of the crossover(s) necessary toproduce the desired genotype.c.
