Petunia flower color is governed by two alleles, but neither allele is truly dominant over the other. Petunias with the genotype RR are red-flowered, those that are heterozygous (RW) are pink, while those with the (WW) genotype have white flowers. This is an example of incomplete dominance. a. If a white-flowered plant is crossed with a red-flowered plant, what is the genotypic ratio of the F1. b. What is the phenotypic ratio of the F1. c. If two of the F1 offspring were crossed, what phenotypes would appear in the F2?. d. What would be the genotypic ratio in the F2 generation?
A. In corn, yellow kernels (Y) are dominant to white kernels (y). If you cross two plants with the Yy genotype, what percentage of the offspring will have yellow kernels? B.What percentage of the offspring will have the same genotype as the parent plants? C.Say you're also interested in corn plant height where tall plants (T) are dominant to short plants (t). You want to save some time and just cross your plants once. The P1 genotypes are YyTT and YYTt. Will you get any short plants with yellow kernels from this cross? Why or why not? D. If these traits, kernel color and height were linked, how would this affect your experimental outcomes? Would you expect the laws of Mendelian genetics to still apply? Why or why not ?
. Flower color in lilies is controlled by an incomplete dominance pattern. Suppose you have two lily plants, both with orange flowers. You cross the two plants and are surprised to find that, half the offspring are orange, but ~25% are red and ~25% are yellow. You decide that you like the red flowers and would like to make more. a) What cross would you perform to produce the most red flowered plants? b) Your mother decides she would like some of the orange flowered lilies. Which cross would give you the most orange flowered plants?
In garden peas, purple flowers (P) are dominant to white (p) flowers, and tall plants (T) are dominant to short plants (t). If a purple tall plant (PpTt) is crossed with a white short blant, what is the expected phenotypic ratio of the offspring? * O 1:1:1:1 purple tall to purple short to white tall to white short O 3:2 purple tall to purple short 9:3:3:1 purple tall to purple short to white tall to white short O 1:1 purple tall to purple short all purple tall
There is a lack of dominance in four o’clock plant flowers. When a red flower is crossed with a white flower, a pink flower is produced. A white four o’clock flower was crossed with a pink four o’clock flower. What is the likelihood of getting red flowers from this cross? Select one: a. 100% b. 50% c. 0% d. 25%
a. Are red flowers crossed with white flowers produce all pink flowers complete dominance, co-dominance, or incomplete dominance? b. Are red flowers crossed with white flowers produce all red flowers complete dominance, co-dominance, or incomplete dominance? c. Are red flowers crossed with white flowers produces all peppermint flowers (red and white striped)
Perform the following crosses: A. If having a widow's peak is dominant to having a straight hair line. What percentage of the offspring of a heterozygote with a homozygous recessive will have a widow's peak? B. Using what you have learned, predict the phenotypes of the offspring in this cross. G = grey g= brown L = long hair A GGLL mates with a ggll. 1 = short hair
In summer squash, white fruit color (W) is dominant over yellow fruit color (w) and disk-shaped fruit (D) is dominant over sphere-shaped fruit (d).. If a squash plant true-breeding for white, disk-shaped fruit is crossed with a plant true-breeding for yellow, sphere-shaped fruit, what will the phenotypic and genotypic ratios be for: a. the F1 generation? b. the F2 generation? You must show the Punnett Square for the F2 generation!
Glory flowers can be tubular shaped (T) or open shaped (t), where T is dominant to t. The flower color exhibits incomplete dominance. Homozygous flowers are purple (P) or white (P’) and heterozygotes are lavender.A dihybrid cross of morning glory plants for flower shape and flower color results in offspring phenotypic ratio for flowers that are ?? Is dihybrid cross TtPp x TtPp or TTPp x ttPp???
In incomplete dominance inheritance, a snapdragon plant that is homozygous for red flowers is crossed with a snapdragon plant that is homozygous for white flowers. What is the probability (%) that the offspring will have red flowers?
When a Chinese hamster with white spots is crossed with another hamster that has no spots, approximately 12 of the offspring have white spots and 12 have no spots. When two hamsters with white spots are crossed, 23 of the offspring possess white spots and 13 have no spots. a. What is the genetic basis of white spotting in Chinese hamsters? b. How might you go about producing Chinese hamsters that breed true for white spotting?
In garden pea plants, the yellow seed colour (Y) is dominant over the green seed colour (y). A true breeding yellow-seeded plant was crossed with a green-seeded plant. All of the F1 generation plants had yellow seeds. Which of the following statements is true for the F1 generation? Select one: a. Half of the F1 generation plants will have the allele for yellow seeds. b. None of the F1 generation plants will have the allele for green seeds. c. All of the F1 generation plants will have the allele for green seeds. d. None of the F1 generation plants will have the allele for yellow seeds.
