For keyboard navigation, use the up/down arrow keys to select an answer. 1/2 1/4 100%Watermelon Genotypic and Phenotypic Ratio Practice Read the information below. Determine the ratios for phenotype and genotype of each Punnett Square.You may use the example from the Punnett Square worksheet as a guide.A genetic engineer is going to cross two watermelon plants to produce seeds for spring planting. He is breeding for size and wants to have many watermelons with the phenotype for long shape as possible. In watermelons, the allele for short shape is (S) is dominant to the allele for long shape. Determine the Genotypic ratios and phenotypic ratios for each Punnett square. Which cross would yield the highest number of long watermelons? Please make sure to write legibly to determine the capital “S” vs the lowercase “s” 1. SS x SS 2. SS x ss 3. SS x Ss 4. Ss x ss 5. Ss x ss 6. Ss x SsThe best way to determine the genotype for a plant presenting with dominant phenotypes is by performing a test cross. Test crosses are always performed with a true-breeding plant with recessive traits. What would be the phenotype and genotype of the plant you would need to perform the test-cross with your tall, purple plant?After performing the test-cross with your unknown purple, tall plant you find that all your resulting plants are tall; half have white flowers, and half have purple flowers. What was the genotype of your original purple, tall plant?
- In plants known as “ four o’ clocks”, the allele for the dominant red- flower color is is completely dominant over the allele for white-flowers. A gardener allows several heterozygous pink-flowered four o'clock to self pollinate and collects 200 seeds. Identify the flower color phenotypes and theoretical percentage.Using a Punnet square, perform a trihybrid cross on the following traits in hybrid form: Height - Tt (tall and short) Flower color - Pp (purple and white) Seed shape - Ss (smooth and wrinkle) Give the phenotypic and genotypic ratio.Green leaves are dominant to red. Long petals are dominant to short. Cross a homozygous green, heterozygous long and a homozygous red, homozygous long. Give phenotypic ratio and show Punnett square.
