A) Describe the data you collect from the Purple 1 x Purple 2 cross. Predict the genotype of each of the parent plants. Explain your predictions using data from the experiment. (Again, you may need to use data from other crosses!) B) Consider the offspring, the next generation (F1), from the Purple 1 x Purple 2 cross. What is the probability of a green stem plant? How do you know this? C) What is the probability in the F2 generation of a green stem offspring? Use a Punnett square(s) and quantitative data to explain your thinking. Upload your Punnett square(s).
How can you determine the genotype of a plant showing the dominant phenotype of red color? A. Cross the red plant with a white plant to see how many red plants appear B. Cross the red plant with other red plants to see if any white plants appear. C. Cross the red plant with a white plant to see if any white plants appear. D. The phenotype reflects the genotype, so the plant must be homozygous for the trait.
Hibiscus plants have different varieties of flowers. In an instance, both the red and white flowers showed that they are incompletely dominant with each other. What will happen if these two varieties are bred? Explain. A) the flowers will have a pink color B) the flowers will grow more petals C) the flowers will have red and white patches D) the flowers will have a red color
In tomatoes, the red fruit color is completely dominant to yellow. Suppose a tomato plant homozygous for red is crossed with one homozygous for yellow and the progeny are allowed to self pollinate. What phenotypes do you predict in the F2 generation? a) 3 red: 1 yellow b) 9 red : 3 orange : 1 yellow c) 1 red : 2 orange : 1 yellow d) 1 red : 1 yellow
You cross two pea plants both from pure breeding lines. One has hairy leaves and the other has smooth leaves. All the offspring have hairy leaves. If you take one of the offspring (F1) and cross it back to smooth-leaved plant what phenotypic ratio do you expect in the next generation? Group of answer choices A. half smooth and half hairy B. all smooth C. all hairy D. 3/4 hairy and 1/4 smooth
shows the results of a cross between a tall pea plant and a short pea plant. a. What phenotypes and proportions will be produced if a tall F1 plant is backcrossed to the short parent? b. What phenotypes and proportions will be produced if a tall F1 plant is backcrossed to the tall parent?
A male plant with genotype AaBBCcDdee was crossed with one heterozygous for all thegenes. (a) what is the probability of getting a pollen with ABcDe genes? (b) of producing anovum with three dominant and two recessive genes? (c) of getting a progeny with samephenotype as the female parent? (d) of progeny with exactly same genotype as the femaleparent? (e) If instead of the above male, the cross was with one heterozygous for all thegenes, what proportion of the offspring will have three dominant phenotypic traits. (f) willbe genotypically like the parents?
In peas, tall is dominant over dwarf. If a plant homozygous for tall is crossed with one homozygous for dwarf : a. What will be the genotype(s) (use the initial of your last name) and phenotype (s) of the F1 plants? b. If the F1 is grown the next season, predict the possible genotypes and phenotypes. c. If you cross the F1 to the tall parent, what phenotype will result of the cross? What will be the ratio of the genotype? d. If you cross the F1 to the short parent, what phenotype will result of the cross? What will be the ratio of the genotype?
In mung beans, the green seed coat (G) is dominant than the brown seed coat (g). If a purebred mung bean which has a green seed coat was cross pollinated to a heterozygous one, what is the ratio of its genotype? A) 1:2:1 B) 1:1:1:1 C) 2:2 D) 2:1
In mung beans, the green seed coat (G) is dominant than the brown seed coat (g). If a purebred mung bean which has a green seed coat was cross pollinated to a heterozygous one, what is the ratio of its genotype? Explain. A) 2:2 B) 1:2:1 C) 1:1:1:1 D) 2:1
A plant that is homozygous for the recessive yellow pod color is crossed with a plant that is heterozygous. Which phenotype will appear MOST in the offspring? A. There will only be plants with green pods. B. There will be more plants with green pods. C. There will be more plants with yellow pods. D. Plants with yellow and green pods will appear in equal numbers.
Cross 1: Purple Stem (P1) x Brown Stem (P2) = F1 Generation (all purple stem plants). Cross 2: F1 x F1 = F2 Generation (295 purple stem plants and 102 brown stem plants). a) What is the phenotype ratio of the F2 generation? b) What is the geneotype ratio of the F2 generation? c) Which trait is dominant?
