3) A red flowered plant is crossed with a white-flowered plant. The resulting offspring are variegated, with patches of red and patches of white. What are the genotypes of the parents and offspring? Which trait, if any, is dominant? Explain.

Answer #1

Let R be the allele of red flower and W for the white plant.

Given that upon crossing the red flower plant with a white flower plant, the offspring are variegated, with patches of red and patches of white. It means that both Red and white allele showed their expression.

In the case of codominance, none of the alleles is recessive and both alleles show their phenotype. So, it the case of codominance.

Since one of the parents is Red, so its genotype will be RR and other plant is white, so its genotype will be WW.

As shown in the cross the genotype of offspring is RW, since it shows the expression of both red and white allele.

5. When two red-spotted tribbles are crossed, 9 of their offspring are red-spotted, 3 are solid red, and 4 are solid white. Two of the solid white tribbles are crossed with a solid red tribble and produce 1/2 solid red tribbles and 1/2 red-spotted tribbles. One of the solid white tribbles when crossed with a solid red tribble produces only solid red tribbles.

In a particular plant, a recessive allele is associated with white flowers (w). The dominant allele (W) results in purple flowers. Two plants are crossed. The offspring are made up of 175 plants with purple flowers and 161 plants with white flowers. Using the allele symbols shown above, the genotypes of the two parents are Ww x ww. This mating is an example of a/an ?

Tallness (T ) in snapdragons is dominant to dwarfism (t ), while red (R ) flower color is incompletely dominant to white (R' ). The heterozygous condition results in pink (RR' ) flower color. The genes for these traits occur on separate chromosomes.

Two corn homozygous, white-seeded corn lines were crossed and all progeny were red-seeded. These red-seeded F1 progeny were selfed, and the population segregated 9 red-seeded:7 white-seeded. Explain these results by determining the number of genes controlling seed coat colors and giving the genotypes of the parents.
