Set 1

1. Austrian monk Gregor Mendel primarily worked with what kind of organisms to do his genetic work?
2. Which of the following are true about Marfan syndrome:
3. Achondroplastic dwarfism is considered a lethal genetic syndrome because;
4. The “A” and “B” alleles in the ABO blood group are recessive to blood type “O.”
5. The control of most human traits by single genes is rare because most traits are the results of multiple genes like human eye color.
6. Amyloid plaques are the suspected cause of Alzheimer’s disease.
7. Since osteogenesis imperfecta can be the result of single gene defects in a number of different genes (genetic heterogeneity) parents who carry the defect in different genes from their partner can produce a child with this syndrome.
8. The law of segregation states that alleles of a gene:
9. Which of the following is true about the Jumping Frenchmen of Maine syndrome
10. LDL is the carrier of cholesterol in the blood.
11. The mitochondrial DNA contains no histones or introns.
12. Protein tau can form sticky“tangles” as part of the cause of Alzheimer’s disease.
13. Mitochondrial genes are primarily transferred from fathers to their children.
14. Cystic fibrosis is caused by a genetic mutation in a:
15. Because Huntington’s disease is so deadly most people alive who have it are children.
16. In Alzheimer’s disease which parts of the brain are affected?
17. A Punnet square follows the transmission of alleles and is based on probability.
18. In autosomal dominant inheritance, a trait can appear in either sex because an autosome (non-sex chromosome) carries the gene.
19. According to widely accepted modern evolutionary ideas mitochondria originated in cells according to;
20. Which of the following is true about Huntington’s disease?
21. The bodies of the Royal Romanovs, the ruling family of Russia in the early 1900s were exhumed in the 1990s and their DNA was sequenced. Geneticists found a variation in the mitochondrial DNA sequence among the royal family members. The variation was explained by the phenomena of:
22. What percent of cases of Alzheimer’s disease are familial (inherited)?
23. A parent who carries a disease gene always shows symptoms of the disease.
24. King George III of England suffered from an autosomal dominant disorder porphyria variegate which caused many symptoms including wild behavior associated with madness. At the genetic level, this is an example of
25. A single gene disorder with many symptoms or a gene that controls several functions or has more than one effect is termed:

Set 2

1. In order for a child to get the genetic-based disease cystic fibrosis which of the following must occur?
2. Which of the following are true about Marfan syndrome:
3. Amyloid plaques are the suspected cause of Alzheimer’s disease.
4. A Punnet square follows the transmission of alleles and is based on probability.
5. A single gene disorder with many symptoms or a gene that controls several functions or has more than one effect is termed:
6. A single gene OCA2 on chromosome 15 confers eye color by controlling melanin synthesis. But also a second gene can influence the expression of OCA2.
7. Which of the following is true about the Jumping Frenchmen of Maine syndrome
8. King George III of England suffered from an autosomal dominant disorder porphyria variegate which caused many symptoms including wild behavior associated with madness. At the genetic level, this is an example of
9. Protein tau can form sticky“tangles” as part of the cause of Alzheimer’s disease.
10. A mutated recessive allele can never contribute to disease.
11. Mendel crossed some yellow round pea plants with wrinkled green pea plants. The traits of yellow and round were dominant. In the first generation, the F1 generation all the offspring were;
12. Using and understanding pedigrees are important today because they help families identify the risk of transmitting an inherited disease
13. In autosomal dominant inheritance, a trait can appear in either sex because an autosome (non-sex chromosome) carries the gene.
14. According to widely accepted modern evolutionary ideas mitochondria originated in cells according to;
15. What percent of cases of Alzheimer’s disease are familial (inherited)?
16. Genetic disease based on altered genes results in “loss of function” or “gain of function” which causes the disease and its symptoms. Huntington’s disease is caused by an abnormally long protein that causes symptoms. This would be classified as:
17. The law of segregation states that alleles of a gene:
18. Genetic disease based on altered genes is caused by either “loss of function” or “gain of function” which causes the disease and its symptoms. Cystic Fibrosis involves a defective anion channel. This would be classified as:
19. Mitochondrial genes are primarily transferred from fathers to their children.
20. A dominant allele masks the expression of a recessive allele.
21. A parent who carries a disease gene always shows symptoms of the disease.
22. Austrian monk Gregor Mendel primarily worked with what kind of organisms to do his genetic work?
23. LDL is the carrier of cholesterol in the blood.
24. Recessive disorders tend to be more severe and produce symptoms earlier than dominant disorders.
25. The Mitochondrial Eve theory is a theory about:
