In this cross the dark purple egg plant (male) is represented as ‘PP’ so the gamete is P. And white egg plant (female) is ‘pp’ so gamete is ‘p’.

For eggplants, there are three colors (phenotypes) : dark purple, light purple and white. A white eggplant is crossed with a light purple eggplant to produce 50% light purple eggplant and 50% white plants. When two plants grown from the light purple eggplants are crossed, what colors and ratio are the offspring’s phenotypes, and what are the genotypes of the light purple plants that were crossed?

In an experiment, homozygous dominant plants with purple flowers were crossed with homozygous recessive plants with white flowers. Mendel collected the seeds from this cross, grew F1-generation plants, crossed them to form a second generation, and then analyzed the plants of the resulting F2 generation. What results did he probably get? 1/2 the F1 and 3/4 of the F2 generation flowers were white 1/2 the F1 and 1/4 of the F2 generation flowers were purple 3/4 of the F1 and...

2. A truebreeding female Drosophila with little wings (lw/lw) and red eyes (pr+/pr+) was crossed to a male with normal wings (lw+/lw+) and purple eyes (pr/pr). All of the F1 appeared wild type.

The snapdragon flower in Tennessee and Alabama are both white. When these two strains of snapdragon were crossed, the resulting F1 produces purple-color flower. When the F1 was self-crossed, the F2 progeny were 540 purple and 420 white. 16. What kind of inheritance pattern is this? A. recessive epistasis B. complete dominance C. dominant epistasis D. codominance E. complementation 17. What is the genotype of the F1 progeny? (let’s assume two involved genes are BB and DD) A. BBdd B....

11. Two white-flowered strains of the sweet pea (Lathyrus odoratus) were crossed producing an F1 with only purple flowers. Random crossings among the F1 produced 97 progeny plants: 54 with purple flowers and 43 with white flowers. a) What is the phenotypic ratio of the F2 generation? b) What are the probable genotypes of the parental generation? c) How would you explain biochemically the relationship between purple and white flowers?

The results for the F2 progeny are shown for a F1 cross using
the two X-linked markers:
w+ and m+.
As shown in the figure, the F1 cross is between the following
two parents:
- a phenotypically wild-type (red eye, full wing), heterozygous
female: w+m+/wm
- a double mutant male (white eye, miniature wing):
wm/Y

1) In the F1 cross, can you infer the genotype for the phenotype
in the female? Why or why not?
