A trait in garden peas involves the curling of leaves. A two-factorcross was made by crossing a plant with yellow pods and curlingleaves to a wild-type plant with green pods and normal leaves. AllF1 offspring had green pods and normal leaves. The F1 plants werethen crossed to plants with yellow pods and curling leaves. Thefollowing results were obtained: 117 green pods, normal leaves115 yellow pods, curling leaves78 green pods, curling leaves80 yellow pods, normal leavesA. Conduct a chi square analysis to determine if these two genesare linked.B. If they are linked, calculate the map distance between the twogenes. How accurate do you think this calculated distance is?
A is dominant over a and B is dominant over b. Genes A/a and B/b assort independently. The parental cross (P) is between true- breeding (homozygous) strains (AA bb x aa BB). The resulting F1 offspring would be [Select ] A F1 x F1 cross gives the F2 generation. The ratio of phenotypes in the F2 generation can be described as [ Select ] In the phenotypic ratio, what number refers to individuals that are: dominant for both traits? [ Select ] recessive for both traits? [Select ] To what phenotypes do the "3"s in the ratio refer? [ Select ] > >
A mouse from a true-breeding population with normal gait was crossed to a mouse displaying an oddgait called dancing. The F1 animals all showednormal gait.a. If dancing is caused by homozygosity for the recessive allele of a single gene, what proportion ofthe F2 mice should be dancers?b. If mice must be homozygous for recessive allelesof each of two different genes to have the dancing phenotype, what proportion of the F2 shouldbe dancers if the two genes are unlinked?(Assume that all the mice in the populationwith normal gait were homozygous fordominant alleles.)c. When the F2 mice were obtained, 42 normal and8 dancers were seen. Use the chi-square test todetermine if these results better fit the one-genemodel from part (a) or the two-gene model frompart (b).
A true-breeding plant with round and green seeds was crossed to atrue-breeding plant with wrinkled and yellow seeds. The F1 plantswere allowed to self-fertilize. What is the probability of obtainingthe following plants in the F2 generation: two that have round,yellow seeds; one with round, green seeds; and two with wrinkled,green seeds?
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.
Tallness (T) in snapdragons is dominant to dwarfness (t), while red (R) flower color is dominant to white (r). The heterozygous condition results in pink (Rr) flower color. A dwarf, red snapdragon is crossed with a plant homozygous for tallness and white flowers. What are the genotype and phenotype of the F1 individuals? Group of answer choices A. TtRr–tall and red B. TtRr–tall and pink C. ttrr–dwarf and white D. TTRR–tall and red E. ttRr–dwarf and pink
In the garden pea, orange pods (o) are recessive to green pods (+), and sensitivityto pea mosaic virus (v) is recessive to resistance to the virus (+). A plant withorange pods and sensitivity to the virus was crossed to a true-breeding plant withgreen pods and resistance to the virus. The F1 progeny were then test-crossed toplants with orange pods and sensitivity to the virus with the following results:160 orange pods, virus sensitive 36 orange pods, virus resistant165 green pods, virus resistant 39 green pods, virus sensitive 1. What are the gamete frequencies of the recombinants and non-recombinants? 2. What are the expected frequencies of the recombinant and non-recombinantgenotypes?
Give only typing answer with explanation and conclusion A true-breeding pea plant with round and green seeds was crossed with a true-breeding plant with wrinkled and yellow seeds. Round and yellow seeds are the dominant traits. The F1 plants were allowed to self-fertilize. What are the following probabilities for the F2 generation? a. An F2 plant with wrinkled, yellow seeds. b. Two out of three F2 plants with round, yellow seeds and one with wrinkled, green seeds. c. Four F2 plants in the following order: one has round, yellow seeds; one has round, green seeds; and two have wrinkled, green seeds. d. An F2 plant will not have round, yellow seeds.
In one study, Gregor Mendel crossed yellow-seeded, tall garden pea with a green-seeded,short garden pea. The F1 offspring were all yellow-seeded and tall. Assumingindependent assortment of these two genes, what phenotypes and proportions did he finamong F2 offspring when the F1 garden peas are allowed to fertilize themselves? Show the solution with punnett square.

In the edible pea, tall (T) is dominant to short (t), and greenpods (G) are dominant to yellow pods (g). List the typesof gametes and offspring that would be produced in thefollowing crosses:a. TtGg * TtGgb. TtGg * TTGGc. TtGg * Ttgg
Two genes in tomatoes are 61 mu apart; normal fruit (F) isdominant to fasciated fruit (f ), and normal number of leaves(Lf ) is dominant to leafy (lf ). A true-breeding plant with anormal number of leaves and fruit was crossed to a leafy plantwith fasciated fruit. The F1 offspring were then crossed to leafyplants with fasciated fruit. If this cross produced 600 offspring,what are the expected numbers of plants in each of the fourpossible categories: normal leaf number, normal fruit; normalleaf number, fasciated fruit; leafy, normal fruit; and leafy,fasciated fruit?
