You want to determine whether genes a and b are linked. What cross would you use and why? How would this cross tell you if they are linked?
Three recessive traits in garden pea plants are as follows: yellow pods are recessive to green pods, bluish green seedlings are recessive to green seedlings, creeper (a plant that cannot stand up) is recessive to normal. A true breeding normal plant with green pods and green seedlings was crossed to a creeper with yellow pods and bluish green seedlings. The F1 plants were then crossed to creepers with yellow pods and bluish green seedlings. The following results were obtained for the F2 offspring: 2059 green pods, green seedlings, normal 151 green pods, green seedlings, creeper 281 green pods, bluish green seedlings, normal 15 green pods, bluish green seedlings, creeper 2041 yellow pods, bluish green seedlings, creeper 157 yellow pods, bluish green seedlings, normal 282 yellow pods, green seedlings, creeper 11 yellow pods green seedlings, normal Construct a genetic map that shows the…
If a pure-breeding purple-flowered pea plant is crossed with a pure-breeding white-flowered pea plant, all the offspring have purple flowers. Suppose two F1 plants are crossed, and 1200 offspring are obtained. How many white-flowered plants will you expect?
In a unique species of plants, flowers may be yellow, blue, red, or mauve. All colors may be true breeding. If plants with blue flowers are crossed to red-flowered plants, all F1 plants have yellow flowers. When these produced an F2 generation, the following ratio was observed: 9/16 yellow: 3/16 blue: 3/16 red: 1/16 mauve In still another cross using true-breeding parents, yellow-flowered plants are crossed with mauve-flowered plants. Again, all F1 plants had yellow flowers and the F2 showed a 9:3:3:1 ratio, as just shown. (a) Describe the inheritance of flower color by defining gene symbols and designating which genotypes give rise to each of the four phenotypes. (b) Determine the F1 and F2 results of a cross between truebreeding red and true-breeding mauve-flowered plants.
Consider this cross in pea plants: Tt Rr yy Aa × Tt rr Yy Aa, whereT = tall, t = dwarf, R = round, r = wrinkled, Y = yellow, y = green,A = axial, a = terminal. What is the expected phenotypic outcomeof this cross? Have one group of students solve this problem bymaking one big Punnett square, and have another group solve it bymaking four single-gene Punnett squares and using the multiplication method. Time each other to see who gets done first.
In the Pea plant, tall plant height (T) is dominant over short (t). Pure-breeding tall and short plants are crossed. A) If the F1 is self-crossed and 400 F2 plants are raised, how many would be expected in each phenotypic class? B) How many of the F2 would be expected to be pure breeding when selfed?
Radish flowers may be red, purple, or white. A cross between a red-flowered plant and a white-flowered plant yields all-purple offspring. The part of the radish we eat may be oval or long, with long being the dominant trait. If true-breeding red-flowered long radishes are crossed with true-breeding white-flowered oval radishes, what would the F1 generations genotype and phenotype be?
You have two true-breeding strains of coneflower. One strain has purple flowers and purple stems. The other strain has white flowers and green stems. When you cross these strains the F1 generation has purple flowers and purple stems. From this information you know that purple flowers is dominant to white flowers and that purple stems is dominant to green stems. In terms of genetic mechanisms, there could be two explanations: (1) flower color and stem color are each controlled by separate, independently segregating genes, and (2) there is one gene controlling both flower color and stem color. A. If explanation #1 is correct what would you see if the F1 generation were self-crossed to produce an F2 generation. Make up appropriate genetic symbols for this model and work out the cross to the F2 generation. B. If explanation #2 is correct what would you see if the F1 generation were self-crossed to produce an F2 generation. Make up appropriate genetic symbols for this model and work out the…
In a dihybrid cross, a homozygous plant with purple and axial flowers (PPAA) is crossed with a homozygous plant with white and top flowers (ppaa). If the purple flower trait is dominant over white flowers and axial flowers are dominant over top flowers, what phenotypic ratio will be produced in the F1 generation? purple and axial flowers: white and top flowers – 3: 1 - purple and axial: Purple and top: white and axial: white top – 9: 3: 3: 1 all plants with purple and axial flowers – 4: 0 purple and axial flowers: white and top flowers – 1: 1 -
) Radish flowers may be red, purple, or white. A cross between a red-flowered plant and a white-flowered plant yields all-purple offspring. The part of the radish we eat may be oval or long, with long being the dominant trait. If true-breeding red-flowered long radishes are crossed with true-breeding white-flowered oval radishes, what would the F1 generations genotype and phenotype be For full credit, you must show all work.
Two true breeding pea plants-one with yellow round seeds (YYRR) and the other with green wrinkled seeds (yyrr)-were crossed. The F1 plants will be dihybrid heterozygous for both the characters (yyRr). The plants were self-pollinated. Will the Y and R alleles always stay together, generation after generation? Or are seed color and seed shape inherited independently of each other? Show how you come to a conclusion.
You decide to cross two true-breeding stocks of pea plants. One parent has blue, axial flowers and the other has white, terminal flowers; all F1 individuals have blue, axial flowers. If you then cross the F1, amongst the F2 offspring, what is the probability of plants with white axial flowers?
