12) In peas, the yellow seed color is dominant (YY or Yy) over the green seed color (vy). You have been given a plant that only produces yellow seeds and need to determine if the plant is YY or Yy. Which of the following crosses would be most effective for determining the genotype of your plant? A)your plant x a plant that produces only green seeds B)your plant x another plant with known genotype YY C)your plant x another plant...

3B. A novice plant breeder is trying to creat a "superdwarf" variety of petunia to use in planters. She starts by crossing two different, pure breeding dwarf varieties together. To her surprise, all the offspring of this cross are tall! When these Fl plants were interbred, the following results were seen in the offspring: 93-tall 68 - dwarf (0 - superdwarf) She comes to you, a genetics expert for an explanation of what is happening a) Explain the inheritance of...

A cross was made between two strains of plants that are agriculturally important. One strain was disease-resistant but herbicide-sensitive; the other strain was disease-sensitive but herbicide- resistant. A plant breeder crossed the two plants and then allowed the F1 generation to self-fertilize. The following data were obtained: F1 generation: All offspring were disease sensitive and herbicide resistant. F2 generation: 170 disease sensitive, herbicide resistant 60 disease sensitive, herbicide sensitive 44 disease resistant, herbicide resistant 10 disease resistant, herbicide sensitive Formulate...

7. If the Fz generation were produced, what proportion of the offspring would you expect to produce 14 pound fruits? a. 1/16 b. 128/256 c. 56/256 d. 47/128 e. 1/256 8. When two 12 pound F2 trees were crossed they produced offspring which all produced 12 pound fruit. However, when these offspring were crossed randomly, the fruit produced weighted from 4 to 20 pounds. What can you say about the possible genotypes of the original F2 trees? 65 AJ. Jones...

Assume that you just calculated baseline allele frequencies for this population So at time TO. Suppose these flies were allowed to mate and produce offspring for the next two weeks. The population is large, rates of mutation at the body color locus are low, and flies cannot enter or leave the source population If the allele frequencies were: f(e)=0.55 and f(E)=0.45, and you waited 2 weeks...

1. In loppins (fictitious diploid invertebrates), ear shape is controlled by two genes with two alleles each; upright ears (F) is dominant to floppy ears (f), and double-pointed ears (P) is dominant to single-pointed ears (p). Moreover, due to genetic interactions, floppy ears are always single-pointed. A loppin with floppy ears is crossed to a loppin with upright single-pointed ears, and the phenotypic ratios in the offspring are 2 floppy : 1 double-pointed upright : 1 single-pointed upright. What are...
