Based on the information shown (picture) draw the pedigree for this family in the space provided below. Make sure to indicate Lee, the proband, with an arrow and use the proper svmbol for individuals who have died from cancer. Remember to also label each generation with roman numerals.
The volantem lumbricus has been found to have a recessive genetic disorder on the X chromosome that leads to deformed wings (w) instead of their normal wing shape (W). Below is a pedigree from the crossing of some of the volantem lumbricus specimens in the lab. The carriers are not indicated in the pedigree. Complete the following for the below pedigree:Indicate the possible genotype for each individual in the pedigree. If they are a carrier then colour in half of the shape to indicate that. To the first daughter that has mated continue on the pedigree given the following info: there must be 6 more individuals added (3 male and 3 female), there must be 2 more generations added, and each generation must include a female and a male in the offspring. *
A male blue tailed gecko was crossed with a female green tailed gecko. All 28 of the off spring had green tails. What are the genotypes of the two individuals that were crossed using the letter B to indicate tail color?
A homozygous purple plant is crossed with a homozygous white plant. Write the cross and offspring in a Punnet square. What is the genotype of phenotype ratios of the first generation (F1)? Gametes: Genotypes: Phenotypes:

Using the numbers of observed F2 progeny provided in the table (attached picture), write a proper hypothesis of your expectations for the phenotypic ratios in the F2 generation and use this to complete the rest of the table.
Shown below is a pedigree for a completely penetrant trait called Adams syndrome in which babies are born blind. This trait occurs when an allele of the adams gene is associated with ≥200 tandem trinucleotide repeats (the normal number is 10). First cousins, III-1 and III-2 married and their first child (IV-1) was blind. For their next child, they decided to do in vitro fertilization with III-1's sperm and III-2's eggs to generate six embryos (labeled E1-6). When each embryo contained eight cells, a single cell was removed and genomic DNA was isolated. PCR reactions using primers that flank the trinucleotide repeat region were then performed and the resulting fragments were fractionated on an agarose gel. PCR reactions using genomic DNA from III-1, III-2 and IV-1 were included as controls. The DNA was visualized using a fluorescent dye and the gel is shown below. Based on this information, select the best answer from the list to the questions below. || E1 = embryo 1 IV E1 E2 E3 E4 E5…
The pedigree below shows a family affected by a disease. Assume that the individuals marked with an asterisk (*) do not carry any allele associated with the affected phenotype, no other mutation spontaneously occurred, and complete penetrance. Answer the following questions below. Use the notation XR for the allele associated with the dominant phenotype and Xr for the allele associated with the recessive phenotype. Q1) Give the genotypes for as many individuals in the pedigree as possible.
Explain the term out-crossing.
Show the cross between a plant which is tall and purple, heterozygous for both traits AND a plant which is short and purple; heterozygous for purple flowers. Use the dihybrid template printout from above for this cross. Insert your picture by clicking on the picture frame and ensure that your picture includes your name.
If the tobacco plant parents are both heterozygous for color, what are the possible genotypes and phenotypes of their offspring? Complete the Punnett square below. What is the expected phenotypic ratio?
A particular flower can be purple, blue, red or white. Two different pure-breeding white plants are crossed and the F1 are then crossed to produce an F2 generation. What might a 9:7 phenotypic ratio in the F2 indicate? A) additivity B) codominance C) recessive lethality D) reciprocal recessive epistasis E) dominant epistasis Explain each answer.
