two questions:
1) In one experiment, Mendel crossed a purple-flowered, tall plant that had come from a previous hybridization (i.e., it was not true breeding) with a white-flowered, dwarf plant. The results were as follows:
• Purple flowers, tall 47
• White flowers, tall 40
• Purple flowers, dwarf 38
• White flowers, dwarf 41
What are the genotypes of both parent plants and all of the 4 classes of progeny?
2) Fur color in tribbles is determined by a pair of alleles B and b. BB and Bb tribbles are black and bb tribbles are white.A white female tribble is bred with a black male tribble. They have 15 white and 18 black baby tribbles. What is the genotype of the male tribble?

C. In garden peas, one pair of alleles controls the height of the plant and a second pair of allele controls flower color. The allele for tall (T) is dominant to the allele for dwarf (t), and the allele for purple (P) is dominant to the allele for white (p). a. A tall plant with purple flowers crossed with a dwarf plant with white flowers produces 1/2 tall with purple flowers and 1/2 tall with white flowers. What is the...

1. A plant with red flowers is crossed with a white-flowered plant of the same species. All the seeds, when grown, produce plants with red flowers. Assuming that the flower color is controlled by a single pair of alleles, which allele is dominant and which is recessive? 2. How does inbreeding increase the incidence of recessive disorders in a population? 3. Why does an individual always have only two alleles for a given gene? 4. In cats, the allele (S) for short fur...

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?

CONTENT QUESTIONS (answer these for credit) 1. In an experiment to trace the inheritance of two traits in pea plants, a researcher decided to look at height, which is controlled by two alleles. The dominant allele T produces a tall plant while the recessive allele t produces a short plant. Flower color is controlled by one gene with two alleles as well. The dominant allele P produces purple flowers, and the recessive p produces white flowers. If the female parent...

In the tubular flowers of foxgloves, wild-type coloration is red while a mutation called white produces white flowers. Another mutation, called peloria, causes the flowers at the apex of the stem to be huge. Yet another mutation, called dwarf, affects stem length. You crossed a red-flowered plant (gene symbol, r) to a plant that is dwarf (gene symbol, d) and peloria (gene symbol, p). All of the F1 plants are tall with red, normal stem flowers. You cross an F1...
