Tall oblong = TToo
Dwarf normal = ttOO
25.
Sperm = tO
Egg = To
26.
TToo × ttOO = TtOo (tall normal)
27.
TtOo × TtOo
Sperm and egg both will have TO, To, tO and to gametes.
| Gametes | TO | To | tO | to |
| TO | TTOO | TTOo | TtOO | TtOo |
| To | TTOo | TToo | TtOo | Ttoo |
| tO | TtOO | TtOo | ttOO | ttOo |
| to | TtOo | Ttoo | ttOo | ttoo |
GR - 1 : 1 : 2 : 2 : 4 : 2 : 2 : 1 : 1
PR - 9 (tall normal) : 3 (tall oblong) : 3 (dwarf normal) : 1 (dwarf oblong)

A tomato plant heterozygous for stem color and fasciation (the dominant alleles linked on the same chromosome) is pollinated by a plant heterozygous for stem color and homozygous recessive for fasciation (that is nonfasciated). 29. What alleles will the sperm carry?_ What alleles will the eggs carry? 30. What are the genotypes of the progeny? What are the phenotypes of the progeny? 31. If the dominant alleles for stem color and fasciation are commonly located on the same chromosome, how...

A mutant dwarf tomato plant with yellow fruit is self-fertilized and the following progeny are produced: Normal size, yellow fruit: 39 plants Normal size, red fruit: 13 plants Dwarf, yellow: 111 plants Dwarf, red : 35 plants a. What are the phenotypes, alleles, and possible genotypes for the two traits? For the alleles designations, you must use the common convention for assigning alleles for plants, includes symbols consistent with how alleles interact. b. What is the most likely genotype of...

In a particular species of tomato plant, the plants can bear fruits of different colors. Suppose a researcher crosses a homozygous plant that bears white fruit with a different stock of homozygous plant that also bears white fruit. In the Fı generation, all of the fruits are red. Two Fı plants are then crossed and the F2 progeny are examined. The F2 generation contains 219 plants with red fruit and 173 with white fruit. Stepl: Determine if there is one...
