Figure 8.10 In pea plants, purple flowers (P) are dominant to white (p), and yellow peas (Y) are dominant to green (y). What are the possible genotypes and phenotypes for a cross between PpYY and ppYy pea plants? How many squares would you need to complete a Punnett square analysis of this cross?
Sunflowers with flowers 10 cm in diameter are crossed with a plant that has 20-cm flowers. The F1 plants have flowers 15 cm in diameter. In the F2 generation, 4 flowers are 10 cm in diameter and 4 are 20 cm in diameter. Between these are 5 phenotypic classes with diameters intermediate to those at the extremes. a. Assuming that the alleles that contribute to flower diameter act additively, how many genes control flower size in this strain of sunflowers? b. How much does each additive allele contribute to flower diameter? c. What size flower makes up the largest phenotypic class?
In a genetic cross between a homozygous tall plant with homozygous purple flowers and a homozygous short plant with heterozygous purple flowers, how many short plants will you expect in the F2 generation if you sample 36 individuals? Both tall and purple are dominant.

Consider a two-factor cross between a pure breeding plants: one with purple flowers and yellow seed pods and another with white flowers and green seed pods. 100% of F1 offspring have purple flowers and green seed pods. If these F1 plants are self-fertilized, what proportion of F2 offspring are expected to have purple flowers and green seed pods? You may assume independent assortment of the flower color and seed pod color alleles. Please give your answer as a decimal rounded to two decimal places (e.g. 0.69).
Consider sweet peas where aabb genotypic class produces purple flowers and all other genoitypic classes have white flowers. A)- If the parental generation is AA bb * aa BB what phenotypic ration do you expect in the F2 generation assuming complete penetrance ? B)- suppose now that only 75% of aabb individuals have purple flowers (that is, the penetrance of this trait is 75%. what phenotypic ratio do you now expect among the F2 plants? Also, in doing these types of crosses, what other phenomena (other than incomplete dominance) could explain the phenotypic ratio answered in part b.
If a cross is made between two plants that are heterozygous for two traits (AaBb), then their offspring should follow the 9:3:3:1 ratio. In this case, A is the dominant allele for purple leaves, and B is the dominant allelle for curly roots. If the two parents were crossed to yield 320 progeny, approximately how many plants with purple leaves and curly roots would you expect? Group of answer choices a.180 b.225 c.25 d.50 As part of a lab experiment, you create a two-locus cross between two plants, and you expect to see a 8:4:2:2 ratio of offspring. You determine the phenotype for 160 offspring, and find the proportions 84:38:19:19. If you use a chi-square test to determine whether the offspring do indeed fit this pattern, how many degrees of freedom would the test have? Group of answer choices a.2 b.3 c.83 d.4

After crossing a tall plant with purple flowers (TtPp) and a dwarf plant with white flowers (ttpp), you obtain the following offspring counts. Assuming independent assortment, what is the expected number of offspring that are short plants with purple flowers? Please round your answer to the nearest integer. phenotype count tall, purple 245 short, purple 252 tall, white 251 short, white 252
A dark-red strain and a white strain of wheat are crossed and produce an intermediate, medium-red F1. When the F1 plants are interbred, an F2 generation is produced in a ratio of 1 dark-red: 4 medium-dark-red: 6 medium-red: 4 light-red: 1 white. Further crosses reveal that the dark-red and white F2 plants are true breeding. Predict the outcome of the F1 and F2 generations in a cross between a true-breeding medium-red plant and a white plant.
Assume that three loci, each with two alleles (A and a, B and b, C and c), determine the difference in height between two homozygous strains of a plant. These genes are additive and equal in their effects on plant height. One strain (aa bb cc) is 10 cm in height. The other strain (AA BB CC) is 22 cm in height. The two strains are crossed, and the resulting F1 are interbred to produce F2 progeny. Give the phenotypes and the expected proportions of the F2 progeny.
