Draw a family tree or pedigree showing the difference in inheritance between an autosomal dominant disorder and an autosomal recessive disorder.
Differentiate between a genetic disorder and a geneticabnormality
Draw the following pedigree and identify the mode of inheritance (only identify by shading individuals who express the trait). Please provide the genotype for each individual. Remember if you cannot identify whether an individual is TT or Tt please use the T- annotation:
The grandmother expresses the trait and the grandfather does not. The first daughter does not express the trait and marries a man who does not express the trait. The second daughter does not express the trait and marries a man who does not express the trait. The son of the first daughter and her husband expresses the trait. The second son of the first daughter and her husband does not express the trait. The second daughter and her husband have twin daughters that do not express the trait.

Draw a pedigree to depict the following family (Write all the genotypes): One couple has a son and daughter with nomal skin pigmentation, Another couple has one son and two daughters with normal skin pigmentation. The daughter from the first couple has three children with the son of the second couple. Their son and one daughter have albinisn (OMIM 203100); their other daughter has normal skin pigmentation.arrow_forward
- six small pedigrees are displayed. Indicate with J (yes) or N (No) if each pedigree is compatible with each of the following types of inheritance.

- Frekles are inherited as an autosomal dominant trait. Red hair is inherited as an autosomal recessive trait. A brown haired, frekled man (heterozygous for both) marries a woman with red hair and no frekles. What are the possible genotypes and phenotypes for their children and in what proportions? Please show ALL work using punnett squares.arrow_forwardAssume that a particular unusual phenotype is caused by an autosomal recessive allele. John marries Jane, and they have a daughter Mia together who has the unusual phenotype. John has a brother Carlos who appears normal. Jane has a sister Margit with the unusual phenotype. John and Jane are not related, and none of their parents have the unusual phenotype. Draw a 3-generation pedigree that depicts the entire scenario and assign the most likely genotypes to each individual. (You can use any letter you wish to represent the gene.) Yes, you should include Jane's parents and sister, and also John's parents and brother, as part of the pedigree. And don't forget Mia!arrow_forwardidentify Mendelian inheritance patterns and pedigree analysis.arrow_forward
- Your brother has an autosomal recessive disorder, while you are unaffected. Neither one of your parents is affected. Explain how this is possible.arrow_forwardAlbinism (lack of skin pigmentation) is caused by an autosomal recessive allele. A man and woman, both normally pigmented, have an albino child together. For this trait, what is the genotype of both parents? Options Below: homozygous recessive homozygous dominant heterozygous hemizygous unknown, because not enough information is providedarrow_forwardIdentify the pattern of inheritance shown in each of the following pedigrees. If the pedigree illustrates more than one (1) mode of inheritance, just choose one. Afterwards, determine the genotype and phenotype of the first 5 individuals in each pedigreearrow_forward
