Homework Answers
Answer 1.
F1 hybrid has a genotype Aa
Self crossing . Aa. *. Aa
Gametes would be A. a . A. a
Chromosome combination would be AA Aa. Aa. aa
I hope this will help you if you like it then give me a thumbs up, thank you!

4. You have crossed blue crabs to red crabs and seen that all the F1 are red. You have then crossed the F1 crabs to blue crabs and obtained 70 red crabs and 22 blue ones. You believe the trait to be Mendelian. Using correct Mendelian terminology describe what you did and what the expected outcome was for each cross (please include a Punnett Square or branch diagram to support your explanation.

You have identified a new species of flowering plant with red flowers instead of the usual blue flowers. You performed a cross and found that all of the F1 plants had purple flowers. When you self-fertilized these F1 plants, the resulting F2 was: Blue flowers: 1034 Purple flowers: 297 Red flowers: 94 What would the expected numbers be if these phenotypes were due to two alleles with incomplete dominance at a single loci? What if these phenotypes were due to...

An F1 tall, round seed pea plant is crossed with a dwarf, wrinkled seed pea plant. The following offspring are observed: Tall, round: 510 Tall, wrinkled: 495 Dwarf, round: 490 Dwarf, wrinkled: 505 a. What is the expected phenotype ratio? WW or ###.#, depending on what you think the answer is. b. What is the calculated chi-square value? Format your answer with 1 significant digit (...).

Genetics questions, i need help!
1) For the Drosophila red/white cross, you crossed red females and white males (w'w, wy). a) Draw the Punnett Square for this cross (F1). What is the ratio of red females:red males? b) Suppose in the F1 generation, you observed 70 red females and 30 red males. Do a Chi- Square Test to test the hypothesis of the ratio you found in part (a) above. Do you accept or reject the hypothesis? c) Draw the...

You cross true-breeding purple and white flowered pea plants. All 202 of the F1 offspring are white. Next you conduct an F1 self cross and yield 312 white and 108 purple F2 offspring. (a) Based on the data, which trait is dominant? (b) Diagram the P and F1 crosses and show F2 offspring. Use symbols of your choice to show each genotype and phenotype. (c) Based on a Chi-Square hypothesis test, do the F2 results fit with what you expect?...

A cross was made between two strains of plants that are agriculturally important. One strain was disease-resistant but herbicide-sensitive; the other strain was disease-sensitive but herbicide- resistant. A plant breeder crossed the two plants and then allowed the F1 generation to self-fertilize. The following data were obtained: F1 generation: All offspring were disease sensitive and herbicide resistant. F2 generation: 170 disease sensitive, herbicide resistant 60 disease sensitive, herbicide sensitive 44 disease resistant, herbicide resistant 10 disease resistant, herbicide sensitive Formulate...

You are studying the inheritance of coat color in guinea pigs. You hypothesize that dark brown fur(B) is dominant to black fur(b). You mate homozygous black guinea pigs with homozygous brown guinea pigs. All of the F1 offspring have dark brown fur. The F1 offspring breed with each other, producing the F2 generation. Your experiment results in 100 F2 offspring, 30 of the F2 offspring are black and 70 of the F2 offspring are brown. Use Chi square analysis to...

(1) One of the standard techniques to determine whether two loci are physically close to one another on the same chromosome is to conduct a "dihybrid cross", a cross of two individuals that are heterozygous at both loci. For example if the two loci have alleles A and a at the first locus and B and b at the second locus then crossing...
