In pea plants yellow seed color, (GG) and round seed shape (WW) seeds are dominant traits, while green color or (gg) wrinkled shape (ww) seeds are recessive traits. You cross a pure breeding plant with yellow wrinkled seeds to a pure breeding plant with green round seeds to generate F1s. When you perform a reciprocal cross you get the same results. You take an F1 male and an F1 female to generate F2 offspring. You take an F2 male with rou and yellow seeds and mate them with an F2 female that has round green seeds. If these F2s produce 108 offspring, how many would be predicted to be green and wrinkled? a) 27 b) 3 c) 4 d) 7 e) 12

In pea plants yellow seed color, (GG) and round seed shape (WW) seeds are dominant traits, while green color or (gg) wrinkled shape (ww) seeds are recessive traits. You cross a pure breeding plant with yellow wrinkled seeds to a pure breeding plant with green round seeds to generate F1s. When you perform a reciprocal cross you get the same results. 9) You take an F1 male and an F1 female to generate F2 offspring. You take an F2 male with round and yellow seeds and mate them with an F2 female that has round green seeds. If these F2s produce 108 offspring, how many would be predicted to be green and wrinkled? a) 27 b) 3 c) 4 d) 7 e) 12
In pea plants yellow seed color, (GG) and round seed shape (WW) seeds are dominant traits, while green color or (gg) wrinkled shape (ww) seeds are recessive traits. You cross a pure breeding plant with yellow wrinkled seeds to a pure breeding plant with green round seeds to generate F1s. When you perform a reciprocal cross you get the same results. If you perform a test cross on a female from the F1 generation, what outcome do you expect in the offspring? a) 4 phenotypes in equal proportions b) 4 phenotypes in unequal proportions c) 2 phenotypes in equal proportions d) 8 phenotypes in unequal proportions e) None of the above
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
A. In corn, yellow kernels (Y) are dominant to white kernels (y). If you cross two plants with the Yy genotype, what percentage of the offspring will have yellow kernels? B.What percentage of the offspring will have the same genotype as the parent plants? C.Say you're also interested in corn plant height where tall plants (T) are dominant to short plants (t). You want to save some time and just cross your plants once. The P1 genotypes are YyTT and YYTt. Will you get any short plants with yellow kernels from this cross? Why or why not? D. If these traits, kernel color and height were linked, how would this affect your experimental outcomes? Would you expect the laws of Mendelian genetics to still apply? Why or why not ?
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.
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…
A type of tomato (Solanum lycopersicum) produces fruit in three possible colors: red, green, and orange. You cross a true-breeding orange-fruited plant with a true-breeding green-fruited plant, and all the F1 offspring are red. You intercross the red F1s, and the resulting F2 generation consists of 108 red-, 40 orange-, and 44 green-fruited plants. 1) What type of epistasis is acting (dominant, recessive, duplicate dominant, or duplicate recessive)? 2) Assign the phenotypes to a modified 9:3:3:1 ratio. (Do not just calculate the actual ratio of the phenotypes.) Red : _____Orange : _____Green: _____
You have a purple-flowered pea plant, but you do not know if it is homozygous (PP) or heterozygous (Pp) for flower color because both genotypes result in the same purple phenotype. Purple color allel (P) is dominant over white flower allel (p). What would you do to determine the genotype of flower color of this plant? Lötfen birini seçin: O a. Crossing the plant with homozygous large flowered pea plant (LL) Ob. Crossing the plant with heterozygous purple flowered pea plant (Pp) Crossing the plant with homozygous dominant purple flowered pea plant (PP) d. Crossing the plant with a plant whose genotype is unknown e. Crossing the plant with homozygous recessive white flowered pea plant (pp)
In watermelons, bitter fruit (B) is dominant over sweet fruit (b), and yellow spots (S) are dominant over no spots (s). The genes for these two characteristics assort independently. A homozygous plant that has bitter fruit and yellow spots is crossed with a homozygous plant that has sweet fruit and no spots. The F1 are intercrossed to produce the F2. What will be the phenotypic ratios in the F2? 2. If an F1 plant is backcrossed with the bitter, yellow-spotted parent, what phenotypes and proportions are expected in the offspring? 3. If an F1 plant is backcrossed with the sweet, non-spotted parent, what phenotypes and proportions are expected in the offspring? 4. In cats, curled ears (Cu) result from an allele that is dominant over an allele for normal ears (cu). Black color results from an independently assorting allele (G) that is dominant over an allele for gray (g). A gray cat homozygous for curled ears is mated with a homozygous black cat with normal ears. All the F1…
In pea plants, purple flowers (P) are dominant over white flowers (p). If a homozygous dominant plant is crossed with a homozygous recessive plant, what proportion of the F1 offspring will have purple flowers? If you let the F1 generation self-pollinate, what proportion of the F2 plants will have white flowers?

Two genes of a flower, one controlling blue (B) versus white(b) petals and the other controlling round (R) versus oval (r)stamens, are linked and are 10 map units apart. You cross ahomozygous blue oval plant with a homozygous white round plant. The resulting F1 progeny are crossed with homozygouswhite oval plants, and 1,000 offspring plants are obtained.How many plants of each of the four phenotypes do youexpect?
