- Fruit fly body color is wild type (meaning normal) Gray = B+ and black = b Fruit fly wing type is wild type normal wings = vg+ and vg = vestigial A fly which was heterozygous for both traits was crossed with a fly that was recessive for both traits. Write the genotype and phenotype that would be expected from this cross. Write the genotype and phenotype percentages that would be expected from this cross.A yellow female is crossed with a gray male. The F1 are intercrossed to produce the F2. Give the genotypes and phenotypes, along with the expected proportions, of the F1 and F2 progeny.A tall, purple flower plant with genotype Tt Pp is crossed with a tall, white flower plant of genotype Tt pp. What is the probability of obtaining progeny with genotype TTpp? Show your work.
- Radishes may be round, oval and lomg. Aside from this, they may be red, purple or white in color. Red x white produces progeny, all of which are purple. If purple oval will be crossed with purple oval, how many types of phenotypes will appear? If purple oval are crossed with white, long radishes, then what genotypic and phenotypic ratios exist in the progeny? Indicate the phenotypes of the offspring.Red fruits (R) in a plant is dominant over yellow fruits (r). A red fruit plant is crossed with a yellow fruit plant. The breeding produces 15 red fruit plants. Write the genotypes of the parentsA homozygous gray female is crossed with a yellow male. The F1 are intercrossed to produce the F2. Give the genotypes and phenotypes, along with the expected proportions, of the F1 and F2 progeny.
- A parental cross between homozygous wild-type red eyed females (X+ X+) were crossed with white eyed males (XwY). The F1 generation consisted of phenotypic X+Xw females and X+Y males. The F2 generation was produced by crossing the F1 generation and consisted of a ratio of 2 red eyed females (X+ X+ and X+ Xw) : 1 red eyed male (X+Y) : 1 white eyed male (XwY). Attached is a picture of a chi square analysis based on the results from the F2 generation. Please discus what conclusions can be made based on the data/findings. What inheritance pattern is this?The image shows a pair of homologous chromosomes from a single parent before gamete production. M1 and M2 are maternal chromosomes, while P1 and P2 are paternal chromosomes. Two traits are shown: D represents seed color (D – green, d – yellow), while F represents flower color (F – purple, f – white). These two traits follow the patterns of basic Mendelian genetics. During crossing-over between the M2 F allele and the P1 f allele, a mutation occurred and the portion of P1 did not reattach to the chromosome. Which of the following explains what would happen to the proportion of white flowers in a population resulting from this mutation? A - There would be an increase in the proportion of white flowers because the f allele is distributed to more gametes. B - There would be a decrease in the proportion of white flowers because the f allele is not distributed to as many gametes. C - There would be an increase in the proportion of white flowers because the f allele would not be masked by the…In sweet pea, gene C or P alone produces white flowers, the purple color being due to the presence of both of these factors. A white-flowered plant crossed with a purple produces progeny of which 3/8 are purple and 5/8 are white-flowered plants. Give the genotypes of the parents and offspring.
- Petunia flower color is governed by two alleles, but neither allele is truly dominant over the other. Petunias with the genotype RR are red-flowered, those that are heterozygous (RW) are pink, while those with the (WW) genotype have white flowers. This is an example of incomplete dominance. a. If a white-flowered plant is crossed with a red-flowered plant, what is the genotypic ratio of the F1. b. What is the phenotypic ratio of the F1. c. If two of the F1 offspring were crossed, what phenotypes would appear in the F2?. d. What would be the genotypic ratio in the F2 generation?If a homozygous tall pea plant is crossed with a homozygous shortpea plant, what are the possible genotype and phenotype of theoffspring? Legend: T- tall pea plant t- short pea plant Genotypes of the parents: TT x tt Question to answer ff: 1. What is the genotypic ratio? 2. What are the possible phenotypes of the offspring? 3. What is the phenotypic ratio?Radishes may be round, oval and lomg. Aside from this, they may be red, purple or white in color. Red x white produces progeny, all of which are purple. If purple oval will becrossed with purple oval, how many types of phenotypes will appear and If purple oval are crossed with white, long radishes, then what genotypic and phenotypicratios exist in the progeny?
