In a species of roses, the alleles RP and RR code for pink roses and red roses, respectively. In this case, the wild-type phenotype is red roses in which the locus exhibits a paramutation. The presence of RP with RR leads to a paramutation of RR to RP", which results in pink roses. This paramutation is 100% penetrant. If a heterozygous rose is crossed with a homozygous red rose, what is the phenotypic ratio of the offspring? O % pink and % red O none pink and all red O all pink and none red O % pink and red

Individuals of genotype AaBb were mated to individuals of genotype aabb. One thousand offspring were counted, with the following results: 474 Aabb, 480 aaBb, 20 AaBb, and 26 aabb. What type of cross is it? Are these loci linked? What are the two parental classes and the two recombinant classes of offspring? What is the percentage of recombination between these two loci? How many map units apart are they?
In a two factor cross, the longest possible map distance is 50 map units. Explain why this is true. How then can genetic maps show two genes that are 70 map units or more apart?
. In corn, the allele A allows the deposition of anthocyanin (blue) pigment in the kernels (seeds), while aaplants have yellow kernels. At a second gene, W–produces smooth kernels, while ww kernels are wrinkled. A plant with blue smooth kernels was crossedto a plant with yellow wrinkled kernels. The progenyconsisted of 1447 blue smooth, 169 blue wrinkled,186 yellow smooth, and 1510 yellow wrinkled.a. Are the a and w loci linked? If so, how far apartare they?b. What was the genotype of the blue smooth parent?Include the chromosome arrangement of alleles.c. If a plant grown from a blue wrinkled progeny seedis crossed to a plant grown from a yellow smoothF1 seed, what kinds of kernels would be expected,and in what proportions?
With regard to the T and t alleles, explain what the wordsegregation means.
In an autotetraploid Chinese primrose (Primula sinensis), the gene controlling stigma color is very near the centromere of the chromosome carrying it. The allele G for green stigma is dominant to g for red stigmas. A homozygous green autotetraploid strain is crossed with a homozygous red autotetraploid strain. a. What phenotypic ratio of green to red is expected if: The F1’s are intercrossed? The F1’s are crossed with red plants
From a series of two-point crosses, the following mapdistances were obtained for the syntenic genes A, B,C, and D in peas:B ↔ C 23 m.u.A ↔ C 15 m.u.C ↔ D 14 m.u.A ↔ B 12 m.u.B ↔ D 11 m.u.A ↔ D 1 m.u.Chi-square analysis cannot reject the null hypothesis of no linkage for gene E with any of theother four genes.a. Draw a cross scheme that would allow you todetermine the B ↔ C map distance.b. Diagram the best genetic map that can be assembled from this data set.c. Explain any inconsistencies or unknown features inyour map.d. What additional experiments would allow you toresolve these inconsistencies or ambiguities?
The alleles his-5 and lys-1, found in yeast, result in cells that require histidine and lysine for growth, respectively. A cross was made between two haploid yeast strains that are his-5 lys-1 and his+ lys+. 973 tetrads were analyzed, with the following pattern: 7 tetrads with 2 his-5 lys+ spores and 2 his+ lys-1 spores 603 tetrads with 2 his-5 lys-1 spores and 2 his+ lys+ spores 363 tetrads with 1 his-5 lys-1 spore, 1 his-5 lys+ spore, 1 his+ lys-1 spores, and 1 his+ lys+ spore Compute the map distance between these two genes using the method that considered double crossovers and the one that does not. Show your work. Which give the higher value? Why? What is the frequency of single crossovers between these genes? Explain. Based on the frequency of single-crossovers, how many double crossovers would one expect? Is positive interference occurring?
In an autotetraploid Chinese primrose (Primula sinensis L.), the gene controlling stigma color is very near the centromere of the chromosome carrying it. The allele G for green stigma is dominant to g for red stigmas. A homozygous green autotetraploid strain is crossed with a homozygous red autotetraploid strain. What phenotypic ratio of green to red is expected if: The F1’s are intercrossed? The F1’s are crossed with red plants
The pedigree below shows that inheritance of a disease that is caused by a late onset, dominant, autosomal mutation that is rare, but only 50% penetrant. The gene that is mutated in the disease is linked at a distance of 10 cm to a microsatellite marker that has alleles numbered 1, 2, and 3. The marker alleles detected in each individual are indicated below. What is the probability that individual A will develop the disease? Explain using an illustration of this occurs.
The A locus and the D locus are so tightly linked that norecombination is ever observed between them. If Ad/Ad is crossed with aD/aD and the F1 is intercrossed,what phenotypes will be seen in the F2 and in whatproportions?
In a breed of cattle, rough coat is dominant over smooth coat and black coat is codominant to red. Is the loci of the two pairs of gene concerned on the same chromosome?
In an autotetraploid Chinese primrose (Primula sinensis L.), the gene controlling stigma color is very near the centromere of the chromosome carrying it. The allele G for green stigma is dominant to g for red stigmas. A homozygous green autotetraploid strain is crossed with a homozygous red autotetraploid strain. d. If the G locus were 50 or more map units from the centromere, what types and proportions of gametes would the F1 be expected to produce? Derive the expected F2 phenotypic ratio.
