- 9. Make a pedigree for each of the following situations. For each individual, write the individual's genotype (when possible) next to the individual's symbol (e.g. O xty, I Gg): a. Two parents do not have cystic fibrosis and they have a daughter with cystic fibrosis and a son who does not have cystic fibrosis. The daughter grows up and she mates with a male who does not have cystic fibrosis. Their only child is a boy and he has cystic fibrosis. b. A man with hemophilia mates with a female without hemophilia. They have one son and one daughter. The daughter has hemophilia and the son does not have hemophilia. The son grows up, and he marries and mates with a female. Their only child is a boy, and he has hemophilia.Phenotypic ratio Type A : Type O = 2:2 or 1:1 Let's Try This! I1.

What type of translocation is depicted by these chromosomes and what are the consequences of this chromosome rearrangement to the individual? this type of translocation is unbalanced and the major consequence here is that the chromosome number is not reciprocated leading to all sorts of problems with non-disjunction.5. There is a helpful shortcut for calculating the probability of genotypes resulting from a dihybrid cross (or any cross considering two or more pairs of alleles) that does not require drawing a very large Punnett square. This is done by first determining the probabilities of each trait alone (using a monohybrid cross) and then using the multiplication rule to combine the probabilities of all the genotypes being considered. Using our TtYy plants above, we would first assign each set of alleles to its own Punnett square as follows: I t Y y T TT Tt Y YY Yy t Tt tt y Yy УУ a. Based on the Punnett squares above, what is the probability of being genotype tt in this cross? b. Based on the Punnett squares above, what is the probability of being genotype YY in this cross? c. Using the probabilities that you just calculated for the genotypes tt and YY, what is the probability of one offspring being both genotype tt and YY in this cross (use the multiplication rule)? d. What is the probability…Dihybrid Cross Practice In a breed of dog called a Doberman, black fur is dominant to brown fur and floppy ears are dominant to straight ears.

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.

Instead of one big square it is much easier to make two small Punnett squares, one for each gene. In the space at the bottom of page, draw the two squares (from 4d and 5b on previous page). Indicate the phenotypic ratios for each square and then multiply to get the combined probabilities. For example, the probability of having both diseases requires multiplying the probability of each event. a. Is the inheritance of an "A" or "a" allele dependent on (or affected by) the inheritance of a "B" or b" allele? Why or why not? (hint: Which of Mendel's Laws is involved?) b. What is the chance that their child will be phenotypically normal (for both genes)? Show your work: c. What is the chance that their child will be genotype aabb (affected with both diseases)?
