Describe genetic linkage. What is the role of location on a particular chromosome in determining if two traits are linked? Describe the role that blood antibodies play in determining which blood types can be transfused into a particular patient. Use several examples to support your assertions. Sex determination is different in birds and mammals. Describe how this difference in sex determination leads to the different probability of inheriting a sex-linked trait in male and female mammals versus birds.

The dosage of X chromosome expression is equalized between male and female mammals. Think about the example of calico cats to answer the following questions. Use Xb to represent the allele for black fur, XB to represent the allele for orange fur. What genotype(s) of female cats is/are expected to have a calico coat? Is it possible to have a calico cat that is male? Explain.
QUANTITATIVE Recall that hemophilia is an X-linked recessive disease. If a woman with hemophilia had children with a man without hemophilia, what is the chance that their first child will have the disease? What is the chance that their first child will be a carrier?
Describe the difference between genotype and phenotype. Give three examples. Is it possible for two individuals to have the same phenotype but different genotypes?
a. Why males and females do not show equal chances of inheriting a trait? b. Is it possible to determine the genotypes of the parents based on the phenotypes of the offspring?
Give typing answer with explanation and conclusion Suppose a woman who is homozygous for Huntington's disease has 12 children? We would expect __________ of them to have the disease. A mother who is heterozygous for the Huntington's disease gene wants to have a baby with a man who is also heterozygous for the gene. What is the likelihood their baby will not have Huntington's disease?
a. Determine if the pedigree below can be for a trait that is X-linked traits. Write the genotype of each individual next to the symbol. b. Is it possible that this pedigree is for an X-linked recessive trait? c. What can you conclude about the children if both parents are affected with an X-linked recessive trait?
The diagram below describes the relationships of genes, alleles, and loci of genetics and how a genotype manifests as a phenotype using the pea plant flower as an example. In this case, the genotype is heterozygous, meaning that the plant carries two different alleles of the gene. Think of a scenario where you have a pea plant that is homozygous recessive in flower color. Determine the phenotype of the flower color for this plant and describe how the phenotype is derived based on the information provided in the below diagram. Make sure to include the following terms, gene, allele, locus, enzyme, and gene expression, in your discussion.
What is a Barr body? How many Barr bodies in a person with genotype XXXXX? How is the structure of a Barr body different from that of other chromosomes in the cell? How does the structure of a Barr body affect gene expression? Color-blindness is an X-linked recessive trait. Heterozygous females are not color blind but they can sometimes have partial color blindness. Explain how this can occur.
Colorblindness and hemophilia are both X-linked traits in humans. Explain how a female who has a defective color vision gene on one X chromosome and a defective blood clotting gene causing hemophilia on the other X chromosome can be neither a hemophiliac nor colorblind? Please discuss the effect of Gene dosage compensation in your answer and in your answer describe the molecular process by which this occurs.
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.
Compare and contrast the following pairs, include examples: 1. Genotype vs. Phenotype 2. Heterozygous vs. Homozygous 3. Dominant vs. Recessive genes 4. Codominance vs. Incomplete dominance
Duchenne muscular dystrophy is an X-linked, recessive disorder in which muscles waste away early in life, resulting in death in the teens or twenties. A man and woman in their late thirties have five children—three boys (ages 1, 3, and 10 years) and two girls (ages 5 and 7 years). The oldest, boy shows symptoms of the disease. What are the probabilities that their other children will develop the disease? Give only typing answer with explanation and conclusion
