A man and both his parents are affected with a disease. His older brother is unaffected. This man marries a woman who is unaffected with this disease. Her father and her younger brother are affected with the same disease, but her mother and youngest brother are unaffected. Assume that this disease is caused by a single gene with two alleles with complete dominance. a. Draw the pedigree of the family above using the correct symbols and numbering. b. What is the chance that the couple will produce an unaffected child? Please show your calculations.

What are the genotypes of the mother and father in the pedigree below? The pedigree shows albinism (an autosomal recessive trait). The shaded shapes represent albino individuals. a. mother - homozygous dominant; father - homozygous dominant b. mother - heterozygous; father - homozygous recessive c. mother - homozygous recessive; father - heterozygous d. mother - heterozygous; father - heterozygous e. mother - homozygous dominant; father - homozygous recessive
The pedigree below shows three generations of a family that carries albinism, an autosomal recessive genetic disease. In the third generation, a child was born with albinism but the genotypes of the rest of the family are unknown. No other family members have the disease. Assume normal, Mendelian genetics with no new mutations. What are the genotypes of the parents of the affected child? A) There is not enough information to determine their genotypes B) Both are homozygous for albinism C) One is hemizygous and one is heterozygous for albinism D) Both are heterozygous for albinism E) One is homozygous and one is heterozygous for abinism
The pedigree below shows the inheritance of a certain disorder. Based on the pedigree chart, is the brachydactyly trait in pedigree dominant or recessive? Explain.
Read the following family history and draw a pedigree to determine the inheritance pattern for achondroplasia. Once the pedigree is assembled , label the genotypes of each individual using a capital "A to represent the dominant allele and a lower case "a " to represent the recessive allele and create a key to identify which version is the achondroplasia allele. If you are unsure of the genotype , label the individual with a "" in place of the unknown allele. Family History : Jada and Noel , both of short stature, have been married for twenty years. They have three children : an eighteen - year-old boy named Shawn , of short stature ; a fifteen- year- old boy named John , of short stature ; and a twelve -year -old girl named Ann , of average height Noel and Jada also had a male child bom with severe achondroplasia who died six months after birth from respiratory failure . Noel's father was of short stature , while his mother was average height . Noel has a brother and a…
The following pedigree traces the inheritance of a certain genetic disease in a family. The circles represent women and the squares represent men. Individuals with darkened shapes have the disease, while individuals with white shapes do not. The lines indicate the relationship between individuals, either through marriage or by birth. Study the chart and then answer the question. How many women have the disease in this pedigree? Five One Four
A couple who are about to get married learn from studying their family histories that, in both their families, theirunaffected grandparents had siblings with cystic fibrosis(a rare autosomal recessive disease).a. If the couple marries and has a child, what is theprobability that the child will have cystic fibrosis?b. If they have four children, what is the chance that thechildren will have the precise Mendelian ratio of 3:1 fornormal:cystic fibrosis?c. If their first child has cystic fibrosis, what is theprobability that their next three children will be normal?
Suppose that goats have one gene that codes for color, where A is brown and a is white. The goats also have another gene that codes for height, where B is tall and b is short. If these two genes are unlinked, what is the probability that a cross between Aa Bb × Aa bb parents will produce three out of five offspring that are white and tall? Enter your answer as a decimal, rather than as a percentage
Below is a pedigree of a human genetic disease in which solid color indicates affected individuals. Assume that the disease is caused by a gene that can have the alleles A or a. a) Based on this pedigree, what is the most likely mode of inheritance? b) What is/are the possible genotype/s of person 1? c) What is/are the possible genotype (s) of person 4 ? Explain your answers.
In humans, the genes for colorblindness and hemophilia are both located on the X chromosome with no corresponding gene in the Y. These are both recessive alleles. If a man and a woman, both with normal vision, marry and have a colorblind son, draw the Punnet square that illustrates this. If the man dies and the woman remarries a colorblind man, draw a Punnet Square showing the type of children that could be expected from the second marriage. How many/what percentages of each could be expected.
Given the pedigree below: Is the trait dominant or recessive? What are the most likely genotypes of individuals I-1 and I-2? What is the probability that individual II-2 is a carrier?
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.
