5. A man with a specific unusual genetic trait marries an unaffected woman and they have four children. Pedigrees of this family are shown in parts (a) through (e), but the presence or absence of the trait in the children is not indicated. For each type of inheritance, indicate how many children of each sex are expected to express the trait by filling in the appropriate circles and squares. Assume that the trait is rare and fully penetrant. If the trait is an autosomal recessive trait If the trait is an autosomal dominant trait If the trait is an X-linked recessive trait If it is a Y linked trait

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. The pedigree below shows the incidence of rare, autosomal dominant disorder called Ehlers-Danlos disease. The pedigree covers three generations of a particular family and also shows individual genotypes at a potential marker locus (M). a) Indicate the phase of all gen II and III individuals.

.a. Mutations in gene “X” are responsible for breast cancer and can be inherited into the next progeny. In one such case, one affected male parent (a father) who had only one affected parent (can be either male or female) too came to a genetic counselor. Upon the testing recommended by the counselor, it has been found that that male parent’s child has a 50% risk of developing the cancer. Can you discuss the inheritance pattern of this disease for this male parent? In which Mendelian disorder, all the children of a mother (both of her alleles of a gene on X chromosome are pathogenic) could also be affected?
5) Humans who have an abnormally high level of cholesterol are said to suffer from familialhypercholesterolemia.  The gene for this disorder is dominant (C).

What is the probability that they will have children that sufferfrom this disorder? please draw the puutnet square and also write the parents and gemtaics top the puutnet square thanks

a) Identify and describe 5 different types of genetic inheritance.(b) In humans, glucose-6-phosphate dehydrogenase deficiency is a recessive X-linkedtrait. Describe the inheritance of this disease, including an example of the possibleoutcomes of:(i) An affected mother and an unaffected father having children. (ii) An affected father and a homozygous unaffected mother having children
Hypophoshatemia is a dominant genetic disorder caused by deficiency of pho[hates in the blood. Assuming the other parent is free of the disorder, males with the disorder will pass it on to all their daughters but not their sons. Females with the disorder will pass it on to approximately half of their children. a.) Is this pattern of inheritance autosomal or sex-linked? Explain b.) Draw a Punnett square to show the inheritance pattern of the disorder in each of the two scenarios
9.) In humans, when a dark-skinned person reproduces with a very light-skinned person, their children may range in color from dark to brown. This occurs because skin color is controlled by more than one gene (the exact # of genes is not known). For your convenience, a table is presented below that shows several possible genotypes & phenotypes: Genotypes Phenotypes AABB Very dark skin AABb or AaBB Dark skin AaBb, AAbb, or aaBB Medium brown skin Aabb or aaBb Light skin aabb Very light skin If a man with dark skin whose genotype is AaBB reproduces with a woman who has light skin (aaBb), what are the possible skin colors that their children will have? Develop a Punnett square and list the possible genotypes & phenotypes.

BIU A- == 三E 12 - Match each of the following examples to the appropriate type of non-Mendelian inheritance. 1. A homozygous recessive genotype for the gene that encodes phenylalanine hydroxylase (which breaks down the amino acid phenylalanine) causes lighter skin color, a musty odor, differences in intellectual development, and seizures. 2. In pea plants, alleles of Gene W control flower color, with the dominant allele (W) leading to purple flower.color, and the recessive allele (w) leading to white flower color. Usually, a genotype of WW or Ww leads to purple flowers. However, when Gene C is homozygous recessive, WW or Ww plants always have white flowers. 3. In mallard ducks, feather coloring is controlled by Gene F. A dominant allele (F) leads to green head feathers, while a recessive allele (f) leads to brown head feathers. In male mallards, inheritance of one or more F alleles always leads to the green head feather trait. But female mallards always have brown head feathers,…
