The F1 flies described in question 1 were mated with brown-eyed flies from a true-breeding line. What phenotypes would you expect the offspring to have? (a) all with red eyes (b) all with brown eyes (c) half with red eyes and half with brown eyes (d) red-eyed females and brown-eyed males (e) brown-eyed females and red-eyed males
) When the F1 bees were backcrossed to the inbred resistant line produced 4 types of offspring in equal numbers: ¼ if the back-cross offspring showed the complete hygienic behavior pattern ¼ of the back-cross offspring showed none of the elements of hygienic behavior ¼ of the back-cross offspring would uncap the cells of the diseased larvae but these workers would not remove the diseased larvae ¼ of the back-cross offspring would remove the diseased larvae (once the experimenter had uncapped the cells of the diseased larvae) Given the genetic model given in part d, do the backcross offspring in part c (from an F1 x resistant line) show evidence of linkage between the U and R gene loci? Give a reason for your answer.
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 certain species of flies, eye color is controlled by sim-·ple dominance by a single pair of alleles. A red-eyed fly was crossed with a white-eyed fly, both of whose parents had white eyes. All of their offspring (both female and male) had red eyes.a. Which is dominant, the allele for red eyesor the allele for white eyes?b. What is the genotype of the white-eyed parents?c. If the white-eyed parent was mated with one of the red-eyed offspring, what phenotypic ratio wouldyou expect regarding eye color?
In pea plants, the allele for round seeds (R) is dominant and the allele for wrinkled seeds (r) is recessive. Under what conditions would we observe wrinkled seeds in a pea plant?A. When the plant has a genotype RRB. When the plant inherits a dominant allele from both parentsC. When the plant inherits a recessive allele from both parentsD. When a plant has a heterozygous allelic pair of the gene for seed shape
In a test cross, peas of an unknown genotype are crossed with peas of a known genotype. In this example, smooth peas are the unknown and wrinkled peas are the known (rr). If half of the offspring from that cross are smooth and half are wrinkled, what is the genotype of the unknown plant? O a. Homozygous dominant: RR O b. Homozygous recessive: rr Oc. Incomplete dominance d. Heterozygous dominant: Rr CLEAR MY CHOICE
A tall pea plant with terminal flowers (flowers on the ends of the stems) is crossed with a short plant thathas axial flowers. All 72 offspring are tall with axial flowers. This is a dihybrid cross with the height andflower position traits showing independent assortment. a. Name the dominant and recessive alleles. b. Give the genotypes of the parents and offspring in this cross. c. Predict the F2 offspring when the tall-axial F1's are allowed to self pollinate.
Consider a plant that has the "Leaf" gene (L) that causes leaves to be either smooth or wrinkled and is inherited through complete dominance. Heterozygotes of the L gene are smooth. A. What are the two alleles of the gene? B. What is the recessive phenotype? C. What is the genotype of a homozygous dominant individual? D. What gametes can a heterozygous individual make? E. Make a Punnett square to predict the percentage or fraction of recessive progeny when two heterozygous individuals are mated. WHOITICS0OTA
Use the figure and the following description to answer the question(s) below. In a particular plant, leaf color is controlled by gene locus D. Plants with at least one allele D have dark green leaves, and plants with the homozygous recessive dd genotype have light green leaves. A true- breeding, dark- leaved plant is crossed with a light- leaved one, and the F1 offspring is allowed to self- pollinate. The predicted outcome of the F2 is diagrammed in the Punnett square shown in the figure, where 1,2,3, and 4 represent the genotypes corresponding to each box within the square. D d D 1 2 4 Which of the boxes marked 1- 4 correspond to plants with a heterozygous genotype? 2 and 3 1 1,2, and 3 2, 3, and 4 3.
a. State a hypothesis explaining the inheritance of flower color in painted tongues. b. Assign genotypes to the parents, F₁ progeny, and F2 progeny for all five crosses. c. In a cross between true-breeding yellow and true-breeding lavender plants, all of the F1 progeny are bronze. If you used F₁ plants to produce and F2 generation, what phenotypes in what ratios would you expect? Are there any genotypes that might produce a phenotype that you cannot predict from earlier experiments, and if so, how might this alter the phenotypic ratios among the F2 progeny?
