Explain in 1 sentence minimum citing two pieces of evidence from the pedigree to support your answer. B. Assuming that the disorder portrayed in this pedigree is very rare, based on your answer in a., what are the most likely genotypes of I-2, Ill-7 and I1-3. C. Based on your answer in a, what are the odds that IV-1 and IV-2 would have an affected male child?a. 1 dominant allele will contribute 120/10 = 12 cm to the base height of the plant.b. The height of the parent plant 1 Genotype of the parent plant 1 – D1D1D2D2D3D3d4d4d5d5 The height of the parent plant 2 Genotype of the parent plant 2 – d1d1d2d2d3d3D4D4D5D5Contributing alleles – D4D4D5D5. The height of the plant without any contributing alleles would be 80 cm. The plant with genotype d1d1d2d2d3d3D4D4D5D5 has 4 contributing allele each of which contributes 12 cm to the base. Hence, the height of the plant with genotype d1d1d2d2d3d3D4D4D5D5 would be 80 + 12 + 12 + 12 + 12 = 128 cm. c. Parents – D1D1D2D2D3D3d4d4d5d5 × d1d1d2d2d3d3D4D4D5D5 Gametes – D1D2D3d4d5 × d1d2d3D4D5 F1 generation – D1d1D2d2D3d3D4d4D5d5 The height of the plants of F1 generation = 80 + 12 + 12 + 12 + 12 + 12 = 140 cm Hence, Genotype of the F1 = D1d1D2d2D3d3D4d4D5d5 Phenotype of…

Although Laurlanthalasa, Princess of the Qualinesti elves, is known for riding into battle on a silver dragon, this is not her main form of transportation. She generally travels by way of griffon. Although the allele for a "crown" of feathers around the head is dominant, it is rarely found in the wild. This may be due to the fact that it makes the griffons stand out, thus making them less effective hunters and more visible to their natural enemies, evil chromatic dragons. This scarcity also makes them prized by elven royalty. Lauralanthalasa was given a breeding pair of bald griffons by an admirer who claims that they are both hybrids for the crowned gene. Create a Punnett Square to determine if Lauralanthalasa will have any chance using these two griffins to produce crowned offspring.

Is this trait dominant or recessive? 2. How do you know? 3. How are individuals III-1 and III-2 related? 4. How would you name the two individuals that have Hitchhiker"s thumb? 5. Name the 2 individuals that were carriers of Hitchhiker's Thumb. 6. Is it possible for individual IV-2 to be a carrier? Why?. A corn geneticist has three pure lines of genotypes a/a ; B/B ; C/C, A/A ; b/b ; C/C, and A/A ; B/B ; c/c. All the phenotypes determined by a, b, and c will increase the market value of the corn; so, naturally, he wants to combine them all in one pure line of genotype a/a ; b/b ; c/c. a. Outline an effective crossing program that can be used to obtain the a/a ; b/b ; c/c pure line. b. At each stage, state exactly which phenotypes will be selected and give their expected frequencies. c. Is there more than one way to obtain the desired genotype? Which is the best way?Assume independent assortment of the three gene pairs. (Note: Corn will self or cross-pollinate easily.
