Dominant and recessive alleles of a gene in garden peas, G and g, cause seeds to be yellow and green, respectively. Dominant and recessive alleles, F and f, of another gene cause seeds to be spotted or not with violet color, respectively. A plant of genotype GGFF is crossed with a plant of genotype ggff, and the F1 are allowed to self-fertilize. The phenotypes and numbers of F2 progeny are shown below: Phenotype of F2 Number yellow, spotted 89 green, spotted 31 yellow, not spotted 29 green, not spotted 11 Are the G,g and F,f genes linked?

Figure 8.10 In pea plants, purple flowers (P) are dominant to white (p), and yellow peas (Y) are dominant to green (y). What are the possible genotypes and phenotypes for a cross between PpYY and ppYy pea plants? How many squares would you need to complete a Punnett square analysis of this cross?
Tallness (T) in a certain plant is dominant to short (t), while red (R) flower color is dominant to yellow (r). The heterozygous condition results in orange (Rr) flower color. A short plant with red flowers, is crossed with a plant homozygous for tallness and yellow flowers. What would be the genotype and phenotype of the F1 individuals? ttRr—short and orange ttrr—short and yellow TtRr—tall and red Ttrr—tall and yellow TtRr—tall and orange
The genes of tall vine, D, and yellow seed, G, are dominant over their respective alleles for dwarf, d, and green, g. What pheno types and genotypes are expected from each of the following crosses? Include phenotypic and genotypic ratio. a) heterozygoes tall, homozygoes yellow x homozygoes tall, heterozygoes yellow b) dwarf, heterozygoes yellow x heterozygoes tall, green c) homozygoes tall, homozygoes yellow x heterozygoes tall, green d) heterozygoes tall, heterozygoes yellow x heterozygoes tall, heterozygoes yellow
Three gene pairs located on separate autosomes determine flower color and shape as well as plant height. The first pair exhibits incomplete dominance, where the color can be red, pink (the heterozygote), or white. The second pair leads to personate (dominant) or peloric (recessive) flower shape, while the third gene pair produces either the dominant tall trait or the recessive dwarf trait. Homozygous plants that are red, personate, and tall are crossed to those that are white, peloric, and dwarf. Determine the F1 genotype(s) and phenotype(s). If the F1 plants are interbred, what proportion of the offspring will exhibit the same phenotype as the F1 plants?
In the Primula plant, the blue flower color is due to malvidin, a pigment encoded by the completely dominant gene (M). Presence of only the recessive gene (m) leads to white flowers. The P locus controls pigment synthesis in the M locus such that dominant gene (P) stops pigment production, and recessive gene (p) allows pigment production. Two plants both having the MmPp genotype were crossed. What would be the probability of getting plants that are pure-breeding for blue flower color?
In radishes, flower color may be red, purple, or white. The edible portion of the radish may be long or oval. When only flower color is studied, no dominance is evident, and red x white crosses yield all purple. Determine the appropriate allele symbols and indicate which genotypes lead to which phenotypes. If the F1 purple plants described above are interbred, what will be the genotype and phenotype ratios in the F2 generation? Regarding radish shape, long is dominant to oval in the typical Mendelian fashion. What will be the phenotype ratios in the F2 generation of a cross between a true-breeding red, long radish and a white, oval radish?
Three recessive traits in garden pea plants are as follows: yellow pods are recessive to green pods, bluish green seedlings are recessive to green seedlings, creeper (a plant that cannot stand up) is recessive to normal. A true breeding normal plant with green pods and green seedlings was crossed to a creeper with yellow pods and bluish green seedlings. The F1 plants were then crossed to creepers with yellow pods and bluish green seedlings. The following results were obtained for the F2 offspring: 2059 green pods, green seedlings, normal 151 green pods, green seedlings, creeper 281 green pods, bluish green seedlings, normal 15 green pods, bluish green seedlings, creeper 2041 yellow pods, bluish green seedlings, creeper 157 yellow pods, bluish green seedlings, normal 282 yellow pods, green seedlings, creeper 11 yellow pods green seedlings, normal Construct a genetic map that shows the…
Colored aleurone in the kernels of corn is due to the dominant allele R. The recessive allele r, when homozygous, produces colorless aleurone. The plant color (not kernel color) is controlled by another gene with two alleles, Y and y. The dominant Y allele results in green color, whereas the homozygous presence of the recessive y allele causes the plant to appear yellow. In a testcross between a plant of unknown genotype and phenotype and a plant that is homozygous recessive for both traits, the following progeny were obtained: colored, green 88colored, yellow 12colorless, green 8colorless, yellow 92Explain how these results were obtained by determining theexact genotype and phenotype of the unknown plant, including the precise association of the two genes on the homologs (i.e., the arrangement).
A pea plant is heterozygous for both pod shape and color. I is the allele for dominant, inflated pod; i is the allele for recessive, constricted pod. G is the allele for dominant, green pod; g is the allele for recessive, yellow color characteristic. Suppose this plant is crossed with a homozygous pea with inflated, green pod, what will be the possible genotype of the offspring? Identify the: Parents’ genes?Parents’ traits?Genes (genotype)?Shape, color? (phenotype)?Genotypic ratio?Phenotypic ratio?
A particular flower can be blue, red, or white. A pure-breeding red-flowered plant is crossed with a pure-breeding white-flowered one. The F 1 are then crossed to produce an F 2 generation.
