The following pedigree shows the pattern of inheritance of red-green color blindness in a family. Females are shown as circles and males as squares; the squares or circles of individuals affected by the trait are filled in black. What is the chance that a son of the third-generation female indicated by the arrow will be color blind if the father is not color blind? If he is color blind?
Sunflowers with flowers 10 cm in diameter are crossed with a plant that has 20-cm flowers. The F1 plants have flowers 15 cm in diameter. In the F2 generation, 4 flowers are 10 cm in diameter and 4 are 20 cm in diameter. Between these are 5 phenotypic classes with diameters intermediate to those at the extremes. a. Assuming that the alleles that contribute to flower diameter act additively, how many genes control flower size in this strain of sunflowers? b. How much does each additive allele contribute to flower diameter? c. What size flower makes up the largest phenotypic class?
Three autosomal recessive mutations in yeast, all producing the same phenotype (m1, m2, and m3), are subjected to complementation analysis. Of the results shown below, which, if any, are alleles of one another? Predict the results of the cross that is not shown—that is, m2 * m3. Cross 1: m1 * m24 F1: all wild-type progeny Cross 2: m1 * m34 F1: all mutant progeny
The trihybrid AaBbCc is crossed to the triple recessive, aabbcc, and the following phenotypes are obtained in the progeny: 64 abc, 11 aBc, 18 aBC, 14 AbC, 17 Abc, 3 ABc, 71 ABC, 2 abCa. Which of these loci are linked?b. Determine the map distance between these genes.
In crosses between mutant mice, you find the following patterns in the genotype for the A locus containing alleles A1, A2, A3 and A4: What would be the best explanation for the inheritance and why?
In tomatoes, dwarf (d) is recessive to tall (D) and opaque (light-green) leaves (op) are recessive to green leaves (Op). The loci that determine height and leaf color are linked and separated by a distance of 7 m.u. For each of the following crosses, determine the phenotypes and proportions of progeny produced.
In barley, a self-fertilizing species that can be crossed fertilized, two true-breeding strains with virescent leaves exist. In strain A, the trait is caused by a cytoplasmic gene. In strain B, it is caused by a recessive nuclear gene. What phenotypes would you expect among the progeny and in what proportions in each of the following: a. cross between homozygous strain A and strain B b. reciprocal cross c. Self-fertilization of the F1 from a d. Self-fertilization of the F1 from b
In a diploid plant species, an F1 with the genotype Mm Rr Ss is test crossed to a pure breeding recessive plant with the genotype mm rr ss. The offspring genotypes are as follows: Genotype Number Mm Rr Ss 687 Mm Rr ss 5 Mm rr Ss 68 Mm rr ss 196 mm Rr Ss 185 mm Rr ss 72 mm rr Ss 8 mm rr ss 679 Total 1900 1. What is the gene order of these linked genes?
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?
A purple flowering, smooth seed dihybrid plant (genotype PpSs) is test crossed with a white flowering, wrinkled seed plant (genotype ppss). These produce progeny in the following numbers of four phenotypes: 24:76:74:26 (purple flower + smooth seed coat: purple flower + wrinkled seed coat: white flower + smooth seed coat: white flower + wrinkled seed coat). a) What is the genotype of the original dihybrid plant? Specify which alleles are on each chromosome of the purple flowering, smooth seed plant (i.e. AB/ab or Ab/aB). b) How many map units separate the colour and seed coat genes? Show your calculations.
In Drosophila, the genes A, B, and C are linked and in the order given. The distances are A-B = 5 m.u. and B-C = 15 m.u. The interval exhibits 20% interference. How many double crossovers would be observed in a three-point cross involving A, B, and C out of 500 progeny?
A fly that is heterozygous at 3 different, independent, autosomal loci (AaBbCc) is crossed to an unknown fly to yield the following progeny phenotypes in the numbers indicated: What was the GENOTYPE of the unknown fly?
