n pea plants, the appearance of flowers along the main stem is a dominant phenotypecalled axial and is controlled by the T allele. The recessive phenotype, produced by theE t allele, has flowers only at the end of the stem and is called terminal. Seedpod form iSdetermined by a second gene. The dominant phenotype inflated is controlled by alleleC, and a recessive constricted form, produced by allele c.A pure breeding axial, constricted plant is crossed to one that is pure-breeding terminal,inflated.A.

In pea plants, flowers may either be axial (A) or terminal (a) flower and purple (P) or white (p). Progenies from a dihybrid cross are as follows: 51 axial purple 75 axial white84 terminal purple 64 terminal white Conduct a COMPLETE chi-square Test to determine of these results support the hypothesis that the parent plant is heterozygous for both traits.
You have an autotetraploid plant with genotype AAaa that undergoes self-fertilization. At least two copies of the dominant allele A are needed to obtain the dominant phenotype. At what frequency will progeny with the dominant phenotype appear? Type your answer as a fraction, with no spaces (e.g., 1/16).

Deduce the inheritance of these phenotypes; useclearly defined gene symbols. Give the genotypes ofthe parents, F1, and F2.b. Predict the outcome of crosses of the F1 with eachparental line.
States) B *In nature, individual plants of Plectritis congesta bear either winged or wingless fruits. Three individual plants were collected from nature (thus not necessarily pure breeding) before flow- ering and were either crossed or self-pollinated. The results are shown below.

Suppose a purple flower heterozygous for stem size is crossed with a large stem (dominant) purple flower. What are the possible genotypes and phenotypes of offspring?
The oval shaped pollen is dominant to round shape pollen. However, the oval shape character has only 35% penetrance. When a heterozygous oval shaped pollen plant is crossed with a homozygous round shape pollen plant, what is the probability that the first pollen produced will be round shape?
In moss, the genes A and B are expressed only in the gametophyte. A sporophyte of genotype A/a ; B/b is allowed to produce gametophytes.a. What proportion of the gametophytes will be A ; B?b. If fertilization is random, what proportion of sporophytes in the next generation will be A/a ; B/b?
In snapdragons red flower colour (CR) is incompletely dominant to white flower colour (CW). The heterozygote has pink flowers. Normal broad leaves (LB) are incompletely dominant to narrow, grass-like leaves, (LN). The heterozygote has intermediate leaf width. If a red-flowered, narrow leaved snapdragon is crossed with a white-flowered broad leaved one, what will be the phenotypes in the F1 and F2 generations, and what will be the proportions of the different phenotypic classes? (You must draw a branch diagram to provide the answer for the F2)
