Monohybrid cross problems 2
for each of the following complete a punnett square and answer the question using your own paper.
1. a tall plant (t) is dominant to short plant (t). if all offspring of a cross are heterozygous, what were the genotypes of the parents?
2. aroundseededplant(r)(r).whatparenta l genotypes will produce offspring that are 50% homozygous dominant and 50% heterozygous?
3. a homozygous round seeded plant is crossed with a homozygous
wrinkled seeded plant. what percentage of the offspring will also be homozygous?
4. in pea plants purple flowers are dominant to white flowers. what parental genotypes would produce offspring that are all heterozygous for the purple trait?
5. a white flowered plant is crossed with a plant that is heterozygous for the trait. what percentage of the offspring will have purple flowers?
6. if out of 100 offspring 74 are purple flowered and 26 are white, what were the probable genotypes and phenotypes of the parents?
7. what are the parental genotypes needed to produce 100% white flowers?
8. in guinea pigs, the allele for short hair is dominant. if all the guinea pigs are born short haired what are the possible genotypes of the parents? (there are two possible combinations.)
9. if a second cross is made using these offspring and results are 3⁄4 short haired while 1⁄4 are long haired can you now determine the exact genotypes of the parents and if so what are they?
