How to reverse engineer a F2 generation? I'm trying to find the genotype,
Step by step
Solved in 2 steps with 1 images
- What if an environmental agent were to cause changes not only in the somatic DNA but also in the germline DNA?Please answer fast Gene B codes for purple-colored flowers while the recessive form of the gene (b) results in pink-colored flowers. Another gene, A, when dominant, activates the transcription of gene B, resulting in purple or pink-colored flowers, while the recessive version of aa, results in white-colored flowers. A homozygous purple-colored flowering plant was crossed with a fully homozygous recessive white-colored flowering plant. The F1 flowering plants were self-crossed to generate the F2 generation. Determine the phenotypes and genotypes for each generation. Explain.Your internship with Dr. Nefario at Gru Industries is going well so far, but a recent mission to obtain a shrink ray requires a special kind of Minion. You identify that the ideal Minion phenotypes for this mission are two eyes, pale yellow, and short. From your previous work, you’ve found that:Two-eyed (D) is completely dominant over one-eyed (d)Yellow (Y) is incompletely dominant with white (y)Tall (T) is completely dominant over short (t) a. The only reproductive individuals you have at the moment (it was surprise mission!) are a true breeding two-eyed, yellow, short Minion and a one heterozygous for each trait. What genotypic ratios would you expect for this crossassuming that each locus is on a different chromosome? What total proportion would you expect to be the desired phenotype for the mission? b. The mission has since been delayed due to lack of financial support, so you’ve got some time. All the individuals from the F1 cross above are now reproductive. Which genotypes would…
- 10 - Mendel crossed two pea plants with round seeds. All seeds of the offspring were round. He then crossed a plant with round seeds to a plant with wrinkled seeds and all offspring had wrinkled seeds. Which of the following is true? a) a mutation occurred b) O the trait does not breed true c) O wrinkled is dominant d) O the plants he used were not true breeding e) round is dominantA woman diagnosed with early-onset Alzheimer's due to a mutation of the APP genehas children with a man that has no family history of familial Alzheimer's. Give the probability of each possible genotype with corresponding phenotype. (The woman has two possible allele combinations. You must show both possibilities)In the fruit fly, dumpy wings (d) and purple eyes (p) are encoded by mutant alleles that are recessive to those that produce wild type traits; long wings (d+) and red eyes (p+). These two genes are on the same chromosome. In a particular lab, two researchers Walt and Jesse crossed a fly homozygous for dumpy wings and purple eyes with a fly homozygous for the wild type traits. The F1 progeny, which had long wings and red eyes, was then crossed with flies that had dumpy wings and purple eyes. Unfortunately, the progeny of this cross somehow escaped. To prevent their other projects from contamination, they decided to spend an exceptionally boring hour in the lab catching and counting the progeny and found the following: long wings, red eyes – 482 dumpy wings, purple eyes – 473 long wings, purple eyes – 23 dumpy wings, red eyes - 22 What is the genetic distance between these two loci? a. 4.5 cM b. 55 cM c. 45 cM d. 49.5 cM e. 4.7 cM
- Red eyes (r), brown color (b), and curled wings (c) are 3 recessive mutations that occur in house flies. These genes have already been mapped: r-b = 12 mu b-c = 18 mu r-c = 30 mu A fly with red eyes, brown color, and curled wings is crossed with a fly homozygous for the wild-type traits. The F1 males are crossed with females with the three mutant traits and 2000 progeny are produced. Find the number of observed double crossovers if the interference is 0.38. O 43 O 62 O 27 O 16In Drosophila, a heterozygous female for the X-linkedrecessive traits a, b, and c was crossed to a male that phenotypically expressed a, b, and c. The offspring occurred inthe following phenotypic ratios.+ b c 460a + + 450a b c 32+ + + 38a + c 11+ b + 9 No other phenotypes were observed.(a) What is the genotypic arrangement of the alleles ofthese genes on the X chromosome of the female?mapping three linked genes, the heterozygous AaBbCc was crossed to aabbcc individual the following phenotypes were obtained: ABC 4 abc 2 ABc 150 abC 141 aBc 18 AbC 20 Abc 30 aBC 35 A) What are the alleles found on each parental chromosome(genotypes of the parents)?

- 36 Linked genes are NOT assorted independently. Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a TRUE b FALSECat fur coat color genetics is interesting. Orange fur is dominant (''B'') to black fur (''b'') and piebald, which is white spotting, is dominant (''S'') to non-white-spotted (''s''). Both of those genes are located on the X chromosome. In addition, in cats, somatic cells exhibit X-inactivation randomly, which explains why there are tortoiseshell cats (when heterozygous, have orange and black spots) as well as calico cats (orange and black but also with white spots). An orange and white spotted male is mated with a tortoiseshell female. State the genotype of the male and the female.How many affected females and males does this pedigree show? (2) Who is the proband? (3) How many generations are included? (4) What kind of inheritance pattern is the disease-causing allele in this pedigree? Why? (5) Who have the same genotype as the proband?
