You are interested in studying the evolution of Rnase-based gametophytic self-incompatibility. You go into a population and identify 4 S-alleles present. These alleles are designated S₁, S2, S3, and S4, and they occur in the sporophyte only as heterozygotes at equal frequency, in each of the 6 possible combinations: S1 S2 S1 S3 S1 S4 S2 S3 S2 S4 S3 S4 Assuming random dispersal of pollen, what fraction of S₁ pollen grains that land on stigmas will be able to fertilize ovules in this population? Why?

The probability that both alleles in the offspring are type A is the product of the probability that the allele from the pollen is A and the probability that the allele from the ovule is A (we will derive this in Section 6.5). What is the probability that the offspring of a homozygous parent is homozygous? What is the probability that the offspring of a homozygous parent is heterozygous?
Some inbred strains of the weedy plant Arabidopsisthaliana flower early in the growing season, but otherstrains flower at later times. Four different Arabdiposisplants (1–4) were crossed, and the resulting progenywere tabulated as follows:Mating Progeny1 × 2 77 late : 81 early1 × 3 134 late1 × 4 93 late : 32 early2 × 3 111 late2 × 4 65 late : 61 early3 × 4 126 latea. Explain the genetic basis for the difference in flowering time. How do you know that among thisgroup of plants, the flowering time trait is influenced by the action of a single 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.

In Question 23, if one chromosome has R and T and the homologous chromosome also has R and T, does linkage matter? What is the single type of genotype that this plant can produce in its gametes?

The numbers of chromosomes in the somatic cells ofseveral oat varieties (Avena species) are: sand oats(Avena strigosa)—14; slender wild oats (Avenabarata)—28; and cultivated oats (Avena sativa)—42.a.

Which of the following is false? Group of answer choices With a pericentric inversion, there is no loss in genetic material. Haploinsufficiency is caused by a duplication event causing increased expression of a gene. An effect of aneuploidy is that it changes the dosages of some genes. Pseudodominance indicates that one of the homologous chromosomes has a deletion. Sterility is a possible effect of autopolyploidy

If an allotetraploid species is made up of two ancestral genomes, A and B, with each of them having a basic chromosome number of seven. The resistance to the pathogen attacking the foliage of plants is controlled by a dominant allele located at the F locus. The recessive alleles F^a and F^b show sensitivity to the pathogen. Plants with at least on F^A allele are resistant to the pathotype 1 and 2 (regardless of the genotype in B genome), and plants with at least one F^B allele are resistant to pathotypes 1 and 3 (regardless of genotype in A genome). What proprtion of the self-progeny of F^AF^a F^BF^b plant will be resistant to pathotype 1, 2 and 3?
This problem leads you through the derivation of acorrected equation for RF in yeast tetrad analysis thattakes into account double crossover (DCO) meioses. A yeast strain that cannot grow in the absence ofthe amino acid histidine (his−) is mated with a yeaststrain that cannot grow in the absence of the aminoacid lysine (lys−). Among the 400 unordered tetrads resulting from this mating, 233 were PD, 11 wereNPD, and 156 were T.a. What types of spores are in the PD, NPD, andT tetrads?b. Are the his and lys genes linked? How do you know? c. Using the simple equation RF = 100 × [NPD +(1/2)T]/total tetrads, calculate the distance in mapunits between the his and lys genes.d. If you think about all the kinds of meiotic eventsthat could occur (refer to Fig. 5.24), you can seethat the calculation you did in part (c) may substantially underestimate RF. What kinds of meioses(NCO, SCO, or DCO) generated each of the tetradtypes in this cross? e. What incorrect assumptions does the simple RFequation…
