A pea plant is heterozygous for three genes (Tt Rr Yy), whereT = tall, t = dwarf, R = round seeds, r = wrinkled seeds, Y = yellowseeds, and y = green seeds. Tall, round, and yellow are the dominanttraits. What is the probability that an offspring from self-fertilizationof this plant will be tall with wrinkled, yellow seeds?
Summer squash exist in long, spherical, or disk shapes. When atrue-breeding long-shaped strain was crossed to a true-breedingdisk-shaped strain, all of the F1 offspring were disk-shaped. Whenthe F1 offspring were allowed to self-fertilize, the F2 generationconsisted of a ratio of 9 disk-shaped to 6 round-shaped to 1 longshaped. Assuming the shape of summer squash is governed by twodifferent genes, with each gene existing in two alleles, propose amechanism to account for this 9:6:1 ratio
Pea PlantsIn pea plants, a round-seed shape (R) is dominant over a wrinkled-seed shape (r). A round-seeded pea plant was crossed with another round-seeded pea plant. What are the genotype(s) and phenotype(s) ratios of the F1 generation? Show all possibilities using Punnett squares. State the F1 generation genotypes and phenotypes.
A cross between two pea plants, both of which grewfrom yellow round seeds, gave the following numbersof seeds: 156 yellow round and 54 yellow wrinkled.What are the genotypes of the parent plants? (Yellowand round are dominant traits.)
Three recessive traits in garden pea plants are as follows: yellowpods are recessive to green pods, bluish green seedlings are recessiveto green seedlings, creeper (a plant that cannot stand up) isrecessive to normal. A true-breeding normal plant with green podsand green seedlings was crossed to a creeper with yellow pods andbluish green seedlings. The F1 plants were then crossed to creeperswith yellow pods and bluish green seedlings. The following resultswere obtained: 2059 green pods, green seedlings, normal151 green pods, green seedlings, creeper281 green pods, bluish green seedlings, normal15 green pods, bluish green seedlings, creeper2041 yellow pods, bluish green seedlings, creeper157 yellow pods, bluish green seedlings, normal282 yellow pods, green seedlings, creeper11 yellow pods, green seedlings, normal Construct a genetic map that indicates the map distances betweenthese three genes?
A plant with genotype AAbbccDDEE is crossed with one that is aaBBCCddee. F1 individuals are selfed. What isthe probability of getting a F2 plant whose genotype is exactly the same as the genotype of one of the originalparents?
A researcher crosses two white-flowered lines ofAntirrhinum plants as follows and obtains the followingresults:pure line 1 × pure line 2↓F1 all whiteF1 × F1↓F2 131 white29 reda. Deduce the inheritance of these phenotypes; useclearly defined gene symbols. Give the genotypes ofthe parents, F1, and F2.b. Predict the outcome of crosses of the F1 with eachparental line.
In the clover butterfly, males are always yellow, but females can beyellow or white. In females, white is a dominant allele. Two yellow butterflies were crossed to yield an F1 generation consisting of50% yellow males, 25% yellow females, and 25% white females.Describe how this trait is inherited and specify the genotypes ofthe yellow parents.
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?
In sesame plants the one-pod condition is dominant (P) to the three-pod condition (p), and a normal leaf (L) is dominant to the wrinkled leaf (l). Pod type and leaf type are inherited independently. Determine the genotypes for the parent producing offspring: 318 one-pod, normal leaf and 98 one-pod, wrinkled leaf PPLl x PPLl, PPLl x PpLl, or PPLl x ppLl ppll x ppLl PPLL x PPLL ppll x ppll
