Dehybrid cross of F1 and F2 generation what is the Phenotype and genotype Ratio:
1). Apterous female (ap) X Sepia male (se).
Answer:
1). Apterous female (ap ap; se+ se+ ) X Sepia male (ap+ ap+ ; se se)------Parents
Wild type progeny (ap+ ap; se+ se)------F1
ap+ ap; se+se X ap+ ap; se+se (F1 x F1)
ap+ se+ |
ap+ se |
ap se+ |

ap+ ap ; se+ se (wild type) |
ap+ ap ; se se (Sepia eye) |

ap ap ; se se (Apterous, sepia) |
Wild type = 9/16
Apterous = 3/16
Sepia = 3/16
Apterous, sepia = 1/16

Dehybrid cross of F1 and F2 generation what is the Phenotype and genotype Ratio: 1). White Male (w/y) X Vestigial Female(vg).
what is the F2 ratio and phenotype of a cross between male bar and female vestigial
2. You cross a homozygous wildtype female Drosophila (fruit fly) with a male that has a black body (bb). You mate two of the F1 (first generation) flies and examine the F2 (second generation) offspring. The phenotypes can be seen in the table below. a. Draw a pedigree to show the P, F1, and F2 generations. You only need to draw one fly with each phenotype for the F2 generation. seen in this cross. the expected values for a cross...
The results for the F2 progeny are shown for a F1 cross using the two X-linked markers: w+ and m+. As shown in the figure, the F1 cross is between the following two parents: - a phenotypically wild-type (red eye, full wing), heterozygous female: w+m+/wm - a double mutant male (white eye, miniature wing): wm/Y Answer the following questions: 1) In the F1 cross, can you infer the genotype for the phenotype in the female? Why or why not? 2)...
4. You cross individuals with the following Genotypes, AaBbDdEeFFGg & AaBbDDEeFfGg. Predict the proportion of offspring that would show the following Phenotype or Genotype? A) all Dominant Phenotypes, B) the Genotype: AabbDdEeFfgg, C) the Genotype: AABbDdEeFfgg, D) the Genotype: aaBbddEeffGg, & E) all Recessive Phenotypes. 5. You cross individuals with the following Genotypes, AaBbDdEeFFgg x AabbDDEeFfGg. If you produce 1000 offspring in this cross, predict the number of offspring that would have the following Phenotype or Genotype? A) all Dominant...
the F1 Generation of a cross between XXX female and a XY male is XXX, XXY, XY and XX what is the F2 generation? (draw punett square)
A dark purple eggplant (male) was crossed with a white eggplant (female). The resulting F1 were all violet (light purple), while the F2 included mostly violet, and some dark purple and white eggplants. Answer the following below. (5 pts.) Type of dominance Male genotype Female genotype F1 progeny cross Phenotype Genotype F2 progeny cross Phenotype Genotype
1. What would be the phenotype for each of the following birds, including their gender? Color Gender Bb ZZi: - bb ZiZi: - BB ZZ: - bb ZW: - Bb ZiW: - 2. Using the phenotypes of the parents and of the progeny given in table 1, determine the genotype of each parent in the first nest. Male Female 3. Using the phenotypes of the parents and of the progeny given in table 2, determine the genotype of each parent...
^^^ 2. How would you tell whether a novel trait is sex-influenced or sex-limited? Compare the F2 generation tables and write a sentence describing the difference between sex-limited and sex-influenced. In males : B+B+ beardless, B+b^b is bearded, B^b B^b is bearded. In females: B+B+ is beardless, B+b^b is beardless and B^bB ^b is bearded. HH is hen feathering in both males and females; Hh is hen feathering in both males and females; and hh in males- cock feathering and...
1. What kind of assortment does the F2 generation exhibit? Which of Mendel’s laws does it support? 2. What are the genotypes of both of the first parent plants? 3. Why do the F1 generation plants only contain tall plants with red flowers? Why are there no short plants or white flowers? 4. According to the activity, what is the genotype for the F1 Generation? What is their phenotype? 5. From the Punnett Square, what is the ratio of short-white...
