This image shows the offspring that result from a dihybrid cross between a plant with wrinkled green seeds and a plant with round yellow seeds. Generation Generation 2 round, yellow wrinkled, yel wrled green How can this graphic be used to support the idea of independent assortment? O The fact that the seeds can be one of two different colors shows that the chromosomes with the seed color gene must sort independently. O The fact that the seeds can be one of two different textures shows that the chrorhosomes with the seed texture gene must sort independently. O The idea that alleles sort independently is supported by the fact that some second generation offspring have trait combinations that the first generation parents do not have.

A pea plant that is (RrYy) is allowed to self-fertilize. Round seed(R) is dominant to wrinkled (r), and yellow seed (Y) is dominant togreen (y). What is the probability of producing the following groupof five seeds: two round, yellow; one round, green; one wrinkled,yellow; and one wrinkled, green?
A seed dealer wants to sell four-o’clock seeds that will produceonly a single color of flowers (red, white, or pink). Explain howthis should be done.
On rare occasions, an organism may have three copies of achromosome and therefore has three copies of the genes on thatchromosome (instead of the usual number of two copies). Forsuch a rare organism, the alleles for each gene usually segregateso that a gamete will contain one or two copies of the gene. Let’ssuppose that a rare pea plant has three copies of the chromosomethat carries the height gene. Its genotype is TTt. The plant is alsoheterozygous for the seed color gene, Yy, which is found on adifferent chromosome. With regard to both genes, how manytypes of gametes can this plant make, and in what proportions?(Assume that it is equally likely that a gamete will contain oneor two copies of the height gene.)

In nature, the plant Plectritis congesta is dimorphic forfruit shape; that is, individual plants bear either winglessor winged fruits, as shown in the illustration.Wingless fruit Winged fruitPlants were collected from nature before floweringand were crossed or selfed with the following results:Number of progenyPollination Winged WinglessWinged (selfed) 91 1*Winged (selfed) 90 30Wingless (selfed) 4* 80Winged × wingless 161 0Winged × wingless 29 31Winged × wingless 46 0Winged × winged 44 0*Phenotype probably has a nongenetic explanation.Interpret these results, and derive the mode ofinheritance of these fruit-shaped phenotypes.

Normally, wild violets have yellow petals with darkbrown markings and erect stems. Imagine you discover a plant with white petals, no markings, andprostrate stems. What experiment could you performto determine whether the non-wild-type phenotypesare due to several different mutant genes or to thepleiotropic effects of alleles at a single locus? Explainhow your experiment would settle the question.
Round seed is dominant over wrinkled. Yellow cotyledon is dominant overgreen. Full pod is dominant over constricted. The genes for these traits arefound on separate chromosomes. If a trihybrid plant is self-fertilized, whatproportion of the progeny will have round seeds in constricted pods?Express answer in fraction form.
In a certain species of flowering plants with a diploidgenome, four enzymes are involved in the generationof flower color. The genes encoding these four enzymes are on different chromosomes. The biochemical pathway involved is as follows; the figure showsthat either of two different enzymes is sufficient toconvert a blue pigment into a purple pigment.→ white → green → blue → purpleA true-breeding green-flowered plant is mated with atrue-breeding blue-flowered plant. All of the plants inthe resultant F1 generation have purple flowers. F1plants are allowed to self-fertilize, yielding an F2 generation. Show genotypes for P, F1, and F2 plants, andindicate which genes specify which biochemicalsteps. Determine the fraction of F2 plants with thefollowing phenotypes: white flowers, green flowers,blue flowers, and purple flowers. Assume the greenflowered parent is mutant in only a single step ofthe pathway
