Textbook Question
Chapter 3, Problem 5P
A cross between two plants that both have yellow flowers produces 80 offspring plants, of which 38 have yellow flowers, 22 have red flowers, and 20 have white flowers. If one assumes that this variation in color is due to inheritance at a single locus, what is the genotype associated with each flower color, and how can you describe the inheritance of flower color?

A plant with red flowers is crossed with a plant with white flowers and the resulting offspring have pink flowers. What type of inheritance pattern does this describe? If two plants with pink flowers are crossed, what will be the resulting phenotypes and in what ratio?
In chickens, a condition referred to as “creeper” exists whereby the bird has very short legs and wings, and appears to be creeping when it walks. If creepers are bred to normal chickens, one-half of the offspring are normal and one-half are creepers. Creepers never breed true. If bred together, they yield two thirds creepers and one-third normal. Propose an explanation for the inheritance of this condition.
2) Consider the flower color in a hypothetical plant. There is one gene (Bb) for flower color and two alleles
involved (B and b). Based on this pattern, what type of inheritance are we talking about? HINT: start by writing
the genotypes for each.
Cross 1:
gives F1:
Cross 2:
What are the parents' genotypes?
b) What are the offspring's genotypes?
gives F2:
Blue-flowered plant x white-flowered plant
all pale-blue-flowered
Pale-blue F1 x pale-blue F1
27 blue
49 pale-blue
24 white

- In a plant, a tall variety was crossed with a dwarf variety. All F1 plants were tall. When F1 * F1 plants were interbred, 9/16 of the F2 were tall and 7/16 were dwarf. (a) Explain the inheritance of height by indicating the number of gene pairs involved and by designating which genotypes yield tall and which yield dwarf. (Use dashes where appropriate.) (b) What proportion of the F2 plants will be true breeding if selffertilized? List these genotypes.arrow_forwardIn 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 ppllarrow_forwardYou are tracing the inheritance of petal color in tropical sandflowers. You suspect that the inheritance follows a dominant epistasis inheritance pattern, based on the following data: 1204 white petals 296 orange petals 101 yellow petals Perform a statistical test to demonstrate whether the data matches your prediction of dominant epistasis. Record your work as much as you can. What is your overall conclusion about inheritance for this flower?arrow_forward
- A pea plant that is heterozygous with regard to seed color (yellowis dominant to green) is allowed to self-fertilize. What are the predicted outcomes of genotypes and phenotypes of the offspring?arrow_forwardRadish flowers may be red, purple, or white. A cross between a red-flowered plant and a white-flowered plant yields all-purple offspring. The part of the radish we eat may be oval or long, with long being the dominant trait. If true-breeding red-flowered long radishes are crossed with true-breeding white-flowered oval radishes, what would the F1 generations genotype and phenotype be?arrow_forwardIn oats, the color of the chaff is determined by a two-gene interaction. When a true-breeding black chaff plant was crossed to a truebreeding white chaff plant, the F1 generation was composed of allblack chaff plants. When the F1 offspring were crossed to eachother, the ratio produced was 12 black to 3 gray to 1 white. First,construct a Punnett square that accounts for this pattern of inheritance. Which genotypes produce the gray chaff phenotype? Second,at the level of protein function, how would you explain this type ofinheritance?arrow_forward
