- Imagine you are performing a cross involving seed color in garden pea plants. What Fi offspring would you expect if you cross true-breeding parents with green seeds and yellow seeds? Yellow seed color is dominant over green. 100 percent yellow-green seeds 100 percent yellow seeds 50 percent yellow, 50 percent green seeds 25 percent green, 75 percent yellow seedsSeveral alleles affect traits of roses, such as plant form and bud shape. Alleles of one gene govern whether a plant will be a climber (dominant) or shrubby (recessive). All F1 offspring from a cross between a true-breeding climber and a shrubby plant are climbers. If an F1 plant is crossed with a shrubby plant, about 50 percent of the offspring will be shrubby; 50 percent will be climbers. Using symbols A and a for the dominant and recessive alleles, make a Punnett- square diagram of the expected genotypes and phenotypes the cross between the F1 offspring and the shrubby plant.In peas, the allele Le produces tall plants and the allele le produces dwarf plants. The Le allele is dominant to le. If a tall plant is crossed with a dwarf, the offspring are distributed about equally between tall and dwarf plants. What are the genotypes of the parents?
- 5. Flower color is determined by the pathway below. You a crossing a true-breeding white-flowered plant thatcannot produce gene A and a true-breeding white-flowered plant that cannot produce gene B.Gene A Gene BWhite White Purplea. What are the genotypes of the P-generation?b. What are the genotypes and phenotypes of the F1 generation?c. What are the genotypes and phenotypes of the F2 generation? What is the phenotypic ratio?(Purple:White)Waxy endosperm (wx), shrunken endosperm (sh), and yellow seedlings (v) are encoded by three recessive genes in corn that are linked on chromosome 5. A corn plant homozygous for all three recessive alleles is crossed with a plant homozygous for all the dominant alleles. The resulting F1 are then crossed with a plant homozygous for the recessive alleles in a three-point testcross. The progeny of the testcross are wx sh V 87 Wx Sh v 94 Wx Sh V 3,479 wx sh v 3,478 Wx sh V 1,515 wx Sh v 1,531 wx Sh V 292 Wx sh v 280 Total 10,756 a. Determine the order of these genes on the chromosome. b. Calculate the map distances between the genes. c. Determine the coefficient of coincidence and the interference among these genes.5. You are handed a mystery pea plant with tall stems and axial flowers and asked to determine its genotype as quickly as possible. You know that the allele for tall stems (T) i dominant to that of the dwarf stems (t) and that allele for axial flowers (A) is dominant to that for terminal flowers (a). (a) What are all the possible genotypes of your mystery plant? (b) Describe the one cross you would do, out of your gardens, to determine the exact genotype of your mystery plant. (c ) While waiting for the results of your cross, you predict the result of each possible genotype listed in part a. How do you do this? Why is this not called "performing a cross"? (d) Explain how the results of your cross and your predictions will help you learn the genotype of your mystery plant.
- 1. Alleles of the gene that determines seed coat patternsin lentils can be organized in a dominance series:marbled > spotted = dotted (codominant alleles) >clear. A lentil plant homozygous for the marbled seedcoat pattern allele was crossed to one homozygous forthe spotted pattern allele. In another cross, a homozygous dotted lentil plant was crossed to one homozygous for clear. An F1 plant from the first cross wasthen mated to an F1 plant from the second cross.a. What phenotypes in what proportions are expectedfrom this mating between the two F1 types?b. What are the expected phenotypes of the F1 plantsfrom the two original parental crosses?5. In garden peas, green pod (P) is dominant to yellow pod (p) and tall stemmed (T) plants are dominant to short stemmed plants (t). Please give the genotypic and phenotypic ratios from the following crosses. a) Homozygous green pod homozygous tall stemmed plant crossed with a yellow pod (homozygous) short stemmed (homozygous) plant. b) Homozygous green pod homozygous tall stemmed plant crossed with a heterozygous green pod heterozygous tall stemmed plant. c) Heterozygous green pod heterozygous tall stemmed plant crossed with a heterozygous green pod heterozygous tall stemmed plant. d) Heterozygous green pod homozygous tall stemmed plant crossed with a yellow pod (homozygous) homozygous tall stemmed plant. These are dihybrid crosses. 7. In pea plants, flower colour and pollen shape are located on the same chromosome. A plant with purple flowers and long pollen (AaBb) is crossed with one that is recessive for both traits (aabb). Calculate the…3. The inheritance of petal color in some plant species is alleged to be codominant. A group of pure (homozygous) white carnations were deliberately pollinated with pollen from pure red carnations. Fertilized seeds were collected, and after germination and growth of this F1 generation, they were allowed to freely pollinate one another. The color of the flower on each plant in the F2 generation was tallied. 239 red, 307 white, and 615 pink plants were recorded. Apply a ?2 analysis to determine the statistical validity of the assumed inheritance pattern. Show every step in your thought process along with all relevant calculations and written support. HINT: For this problem, you should DEFINITELY construct the two Punnett squares to reveal the phenotypes of the F1 and F2 generations. Please answer very soon will give rating surely
- 1. Hereditary deafness in dalmations (d) is a recessive trait. What percentage of the progeny of crossing DD × Dd will be expected to be a carrier of the deafness allele, but not deaf? (enter a number only) 2.In snapdragons, a flowering plant, red (R) flower colour is dominant to white (r). The heterozygous condition results in pink flower colour. If a two pink flowered snapdragons are crossed, what is the resulting phenotype ratio? Select one: a.2:2 b.1:1:1:1 c.1:2:1 d.3:1 e. (all will be the same)1. Suppose that in plants, smooth seeds (S) are dominant to wrinkled seeds (s) and tall plants (T) are dominant to short plants (t). A tall plant with smooth seeds was backcrossed to a parent that was short and wrinkled. What proportion of the progeny is expected to be heterozygous for tall and smooth? 2. Sickle cell anemia is a recessive trait in humans. In a cross between a father who has sickle cell anemia and a mother who is heterozygous for the gene, what is the probability that their first three children will have the normal phenotype?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 ?
