The plant blue-eyed Mary grows on Vancouver Islandand on the lower mainland of British Columbia. Thepopulations are dimorphic for purple blotches on theleaves—some plants have blotches and others don’t. NearNanaimo, one plant in nature had blotched leaves. Thisplant, which had not yet flowered, was dug up and takento a laboratory, where it was allowed to self. Seeds werecollected and grown into progeny. One randomly selected (but typical) leaf from each of the progeny is shown inthe accompanying illustration.a. Formulate a concise genetic hypothesis to explainthese results. Explain all symbols and show all genotypicclasses (and the genotype of the original plant).
In a plant, fruit color is either red or yellow, and fruit shape iseither oval or long. Red and oval are the dominant traits. Twoplants, both heterozygous for these traits, were testcrossed, withthe results shown in the following table.

One form of male sterility in corn is maternally transmitted. Plants of a male-sterile line crossed with normalpollen give male-sterile plants. In addition, some lines ofcorn are known to carry a dominant nuclear restorer allele (Rf ) that restores pollen fertility in male-sterile lines.a. Research shows that the introduction of restoreralleles into male-sterile lines does not alter or affectthe maintenance of the cytoplasmic factors for malesterility. What kind of research results would lead tosuch a conclusion?b. A male-sterile plant is crossed with pollen from aplant homozygous for Rf. What is the genotype of theF1? The phenotype?c. The F1 plants from part b are used as females in atestcross with pollen from a normal plant (rf/rf ). Whatare the results of this testcross? Give genotypes andphenotypes, and designate the kind of cytoplasm.d. The restorer allele already described can be calledRf-1. Another dominant restorer, Rf-2, has been found.Rf-1 and Rf-2 are located on different…
In corn, a triple heterozygote was obtained carrying themutant alleles s (shrunken), w (white aleurone), andy (waxy endosperm), all paired with their normal wildtype alleles. This triple heterozygote was testcrossed, andthe progeny contained 116 shrunken, white; 4 fully wildtype; 2538 shrunken; 601 shrunken, waxy; 626 white;2708 white, waxy; 2 shrunken, white, waxy; and 113 waxy.a. Determine if any of these three loci are linked and,if so, show map distances.b. Show the allele arrangement on the chromosomesof the triple heterozygote used in the testcross.c. Calculate interference, if appropriate.

A plant of phenotype 1 was selfed, and, in the progeny,there were 100 plants of phenotype 1 and 60 plants ofan alternative phenotype 2. Are these numbers compatible with expected ratios of 9:7, 13:3, and 3:1?Formulate a genetic hypothesis on the basis of yourcalculations
In a species of plant, two genes control flower color. The redallele (R) is dominant to the white allele (r); the color-producingallele (C) is dominant to the non-color-producing allele (c). Yoususpect that either an rr homozygote or a cc homozygote willproduce white flowers. In other words, rr is epistatic to C, andcc is epistatic to R. To test your hypothesis, you allowed heterozygousplants (RrCc) to self-fertilize and counted the phenotypesof the offspring. You obtained the following data: 201 plantswith red flowers and 144 with white flowers. Conduct a chisquare test to see if your observed data are consistent with yourhypothesis.
