- In tomatoes, regular leaves (L) are multilobed and serrated and potato leaves (l) are broad, smooth, and single (Image 1). Red fruit (F) is dominant to yellow fruit (f). A cross is carried out between two pure lines of tomato plants, one having regular leaves and red fruit and the other having potato leaves and yellow fruit. The F1 generation all have regular leaves and red fruit. The F1individuals are then crossed with one another. Complete a Punnett square to determine the expected F2 progeny on the basis of Mendel’s Law of Independent Assortment, which states that the alleles for one gene segregate independently of the alleles for other genes during gamete formation. The information below represents two sets of data collected from the above cross.

- Waxy endosperm (wx), virescent seedling (v), and shrunken endosperm (sh) are all recessive mutants in corn. Waxy and shrunken are both on chromosome IX, located 18 map units apart. Virescent is on chromosome V and is not linked to the other loci. A strain of corn that is homozygous for waxy and virescent is crossed to a strain that is homozygous for shrunken endosperm. The F1 were entirely wild type. An F1 individual was then test crossed to a strain that is homozygous for waxy, virescent, and shrunken. Of 1,000 offspring, how many of the offspring will be virescent and shrunken, but not waxy? Using the information from Problem 1, how many of the offspring will be waxy, virescent, and shrunken?F2 Cross: Tall, White, Axial x Dwarf, Violet, Terminal DdwwAA x ddWWaa Character: Stem height, Flower color & position Use fork-line method to check the possible offspring.

Pp D. whiteTall plant (D) is dominant to dwaf (d), and purple flower color (W) is dominant to white flower color (w). In order to determine the genotype of a tall plant with purple flowers, you decide to conduct a test cross. What should be the genotype of the plant you use to carry out the test cross?Round seed is dominant over wrinkled. Yellow cotyledon is dominant overgreen. Full pod is dominant over constricted. The genes for these traits arefound on separate chromosomes.
