(7) In a family-based alcohol use disorder genetic study, a total of 50 families, each with a pair of siblings, were recruited. The result showed that 12 families have the 1" siblings with marijuana dependence and the 2nd siblings without the disorder, while another 11 families are opposite (i.e. the 1st siblings without the disorder but the 2nd siblings with the disorder). In contrast, 20 families have both siblings exhibiting the disorder and another 17 families have both siblings without the disorder. What kind of heritability can you calculate using this family study and what is the heritability value for alcohol use disorder? A) Narrow-sense heritability, approximately 88% B) Narrow-sense heritability, approximately 44% C) Broad-sense heritability, approximately 88% D) Broad-sense heritability, approximately 44%

1 (b). Nowadays, newborn babies are required to be tested for phynylketonuria (PKU), an autosomal recessive genetic disorder. If untreated, individual homozygous for PKU suffer mental retardation. In a recent year, 4 PKU babies were detected out of 126,o00 tested. Assuming Hardy-Weinberg conditions, What is the percentage of heterozygous carriers?

That means make sure that you are showing at least one Punnett square. Interpret your answer. A Punnett square alone will not suffice. Indicate which types of problems or vocabulary are difficult for you so that we can review them in discussion. Monohybrid cross: A single trait is crossed with only two variations of the allele. with 2. In humans, brown eyes are usually dominant over blue eyes. Suppose a blue-eyed man marries a brown-eyed woman whose father was blue eyed. What proportion of their children would you predict would have blue eyes? A brown-eyed man whose father was brown eyed and whose mother was blue eyed married a blue eyed woman whose father and mother were both brown-eyed. The couple has a blue-eyed son. For which of the individuals mentioned can you be sure 3. of the genotypes? What are their genotypes?…
I have seen that this was answered as C, Why is the answer C, how is that not evidence of it being genetic? Shouldnt it be none of the above?

Although Laurlanthalasa, Princess of the Qualinesti elves, is known for riding into battle on a silver dragon, this is not her main form of transportation. She generally travels by way of griffon. Although the allele for a "crown" of feathers around the head is dominant, it is rarely found in the wild. This may be due to the fact that it makes the griffons stand out, thus making them less effective hunters and more visible to their natural enemies, evil chromatic dragons. This scarcity also makes them prized by elven royalty. Lauralanthalasa was given a breeding pair of bald griffons by an admirer who claims that they are both hybrids for the crowned gene. Create a Punnett Square to determine if Lauralanthalasa will have any chance using these two griffins to produce crowned offspring.

The world can be a scary place. There are many disease causing organisms and genetic disorders that can make life difficult. As you read the chapter, be thinking about your family history of genetic disorders, how these disorders are passed on through generations, and what types of testing can be done to look for these alleles. In this exercise you will reflect on the pros and cons of genetic testing and how it may affect you. Please remember to add a question to engage your classmates in the discussion. What might the consequences be of having this information (e.g. health insurance coverage, privacy, etc.)?
