Wavy hair is intermediate to straight and curly hair. Similarly, medium-sized nose may be inherited if one parent has a large nose and the other parent has a small nose. Wendel has wavy hair, large nose, and type A blood. His father is type O. What is the complete genotype of Wendel? Krisha has straight hair, medium-sized nose, and type AB blood. 2. What is the complete genotype of Krisha? Assuming that Krisha and Wendel would marry, what is the probability that they will have a: 3. Son with the same traits as Wendel? 4. Daughter with the same traits as Krisha? 5. Child with curly hair, small nose, and type O blood?

Porphyria is a genetic disorder caused by the inability to properly metabolize a component of hemoglobin. King George III is suspected to have been afflicted with this disorder. Assume that both George and his Queen suffered from this disorder and they had one afflicted child and one normal child. Is porphyria inherited in a dominant or recessive fashion? What must be the genotype of both George and his Queen? Using punnett square, show ALL work used to achieve your answer.
A woman with fair skin, blond hair, and blue eyes gives birth to fraternal twins; the father has dark brown skin, dark hair, and brown eyes. One twin has blond hair, brown eyes, and light skin, and the other has dark hair, brown eyes, and dark skin. What Mendelian law does this real-life case illustrate and explain what this means in terms of the inherited alleles for these genes?
Hair texture is determined by gene c in an incomplete dominance inheritance pattern, where the heterozygous condition (c1c2) results in wavy hair. Hairline is controlled by gene H, where a widow's peak is dominant to a straight hairline. If a woman with curly hair and a straight hairline has a child with a man with a widow's peak and straight hair (his mom had a straight hairline), what is the chance they would have a kid that has exactly the same hair as mom? Draw the Punnett square and demonstrate the possible genotypes and phenotypes that could result from these two parents' mating.
Albinism is a recessive disorder where there is a lack of melanin. Andrea and her husband Claude both have normal skin pigmentation. Andrea’s mother has the albino phenotype, but her father and her brother do not (normal pigmentation). Claude’s parents are both normal, but he has a sister who has the condition (is albino). Answer the following questions If Andrea and Claude are carriers for the albino allele, what is the probability that they have an albino child? If Andrea and Claude have a second child, what is the probability this child be normal (non-albino)? NOTE: Draw a punnet square or show your work.
Using the pedigree chart attached: Above is a pedigree for colorblindness. Based on the pedigree, is the disease dominant or recessive and is it sex-linked or autosomal? Why? Furthermore, what is the probability that 18 on this chart is affected but the condition, and what is the probability that 18 is a carrier? Why? Are the probability of being a carrier and an affected individual different? Why?
Below is a pedigree of a human genetic disease in which solid color indicates affected individuals.

In humans, the genetic disease cystic fibrosis is caused by a recessive allele (a). The normal (healthy) allele is dominant (A). What is the genotype of someone who has cystic fibrosis? What are the two different genotypes that a healthy person could have? If two people were both heterozygous for the cystic fibrosis gene, what fraction of their children would be likely to have this disease? Hint: Draw a Punnett square to figure it out.
A man with blood type O (genotype ii) has a father with blood type A and a mother with blood type B. Is this man a legitimate child of these parents? What is a possible phenotype of an individual that results from a woman with type AB blood and a man with type B blood? Explain with diagrams.
What phenotypes, in what ratios, would you expect from crossing a person with blood type AB (IAIB) with a person with blood type O (ii)? Explain how this ratio of phenotypes is different than what is predicted by Mendelian inheritance.
