5. The pedigree below traces the inheritance of Albinism, a genetic disorder. Affected individuals, indicated here by the coloured circles and squares, are unable to make a normal amount of melanin, the chemical that is responsible for eye, skin, and hair colour. Does Albinism appear to be caused by a dominant allele or by a recessive allele? Fill in the genotypes of the individuals whose genotypes can be deduced. What genotypes are possible for each of the other individuals? Explain! Naruto Hinata Reiner Asta Hange Mikasa Eren Historia Luffy Nezuko Zenitsu Tanjiro Son Goku

6. The pedigree below traces the inheritance of a particular disorder. Circles are females, squares are males. Shaded symbols are affected with the disorder (NOTE: "half-shaded" symbols are NOT used here, for heterozygous individuals). What is the mode of inheritance of this disorder: is it dominant or recessive? Autosomal or X-linked? What is the genotype of the three numbered individuals? 1 2. 3.
1. Construct pedigree charts using the inheritance of hemophilia in figure 92. This is X-linked inheritance so you are required to label XX for females and XY for males. The gene responsible for the trait is represented by the superscript which should be specified in the legend.
1. In the pedigree below, Use "A" for the allele associated with the dominant phenotype, and lowercase "a" for the allele associated with the recessive phenotype. Determine what is the most likely mode of inheritance of this disease (whether it is inherited as the result of an autosomal dominant or autosomal recessive trait). Write the most probable genotype for each individual based on the mode of inheritance you have determined. Show how all the partners are crossed and the expected offspring produced (You may use Punnett Square) 1 dró || IV
1. Hair or fur length in cats is controlled by a single, autosomal gene; the short hair-allele is dominant to the allele for long hair. Hair color is produced by a different gene which is located on the X chromosome. One allele for this sex-linked gene produces yellow, while an alternate allele produces black fur color; individualswhich are heterozygous for these alleles are calico or tortiseshell in color.If a long-haired, black male is mated with a calico female homozygous for short hair what kind of kittens will be produced in the Ej generation? Give both genotypes and phenotypes; express the genotypes bothsymbolically and in words. Label answers clearly!!
3. In the family pedigree shown in the following chart, an abnormal trait is inherited as a simple recessive. Unless there is evidence to the contrary, assume that the individuals who have married into this family do not carry the recessive gene for the trait. Colored squares and circles represent expressions of the trait (see figure). Calculate the probability of the trait appearing in a given offspring if the following cousins and second cousins in generations III and IV should marry:_ (a) III-1 x III-12; (b) III-4 x III-14; (c) III-6 x II-13: (d) IV-1 x IV-2 2 3 10 11 12 13 14 15 16 IV 2
1. A man and both his parents are affected with a disease. His older sister is unaffected. This man marries a woman who is also affected with this disease. Her father is affected, but her mother and younger brother are unaffected. Assume that this disease is caused by a single gene with two alleles with complete dominance. Draw the pedigree of the family above using the correct symbols and numbering. (3) What is the chance that the couple will produce an unaffected child? Please show your calculations
1. In guinea pigs, two different genes affect the coat. One gene codes for coat color and there are 2 codominant alleles C1=Brown and C2=White. The heterozygous form is tan colored. The second gene codes for presence of hair with H=hairy (dominant) and h=hairless (recessive). If we didn't know the genotypes of the parents, but mom is hairless and dad is tan haired, and the babies produced included brown, tan, white, and hairless, can you guess the genotypes of the parents? Show your work below (explain how you came up with the answers)
1. Red-green colorblindness is caused by a recessive allele (x) at an X-linked gene, and albinism is caused by a recessive allele (a) at an autosomal gene. A phenotypically normal woman (Sara) has a father who is colorblind, and she knows that she is a carrier for albinism. She plans to have a child with a colorblind man (Abdul) who is also a carrier for albinism. What is the probability that Sara and Abdul's child will have one of the conditions, but not both? (C. Follow the steps below to answer this question. a) What is the cross? b) What are the target genotypes? Note: it might be useful to come back to this one and double- check it after you have completed step c, below. Break this down to the single gene level by answering the following questions: a. What is the proportion of normal to albino offspring? Show the Punnett square: b. What is the proportion of normal to colorblind offspring? Show the Punnett square: d) What is the probability that Sara and Abdul's child will have one…
6. A person is simultaneously heterozygous for two autosomal genetic traits. One is a recessive condition foralbinism (alleles A and a); this albinism gene is foundnear the centromere on the long arm of an acrocentricautosome. The other trait is the dominantly inheritedHuntington disease (alleles HD and HD+). TheHuntington gene is located near the telomere of oneof the arms of a metacentric autosome. Draw all copies of the two relevant chromosomes in this person asthey would appear during metaphase of (a) mitosis,(b) meiosis I, and (c) meiosis II. In each figure, labelthe location on every chromatid of the alleles forthese two genes, assuming that no recombinationtakes place.
1. Use the diagram of the pedigree above, which shows inheritance of an x-linked recessive trait through a family. Select ALL of the individuals in the pedigree who must be carriers for the trait. E G B C H A
7. A couple with widow's peaks, an autosomal dominant trait, have two grown daugh- ters and one grown son. The daughters do not have a widow's peak (straight hair line). Their son does have a widow's peak. He married a straight hair lined woman, and they have two daughters. Draw a pedigree that represents this scenario tracking the straight hair lined trait. Make sure to label all generations and provide potential genotypes for each individual on the pedigree. 8.
