18. Category 2 30 Why are most dominant genetic diseases caused by mutations?

19. Category 2 30 Why are most dominant genetic diseases caused by mutations? Victims do not survive to have children unless the disease appears at older age.

20. Category 2 40 This graph indicates multiple allelic frequencies such as blood type True false

21. Category 2 40 This graph indicates multiple allelic frequencies such as CF True False- It does show multiple allelic, but like height.( CF is recessive, not multiple allelic.)

24. Category 3 questions follow

25. Category 3 10 Why is Karyotyping only used to identify genetic diseases caused by nondisjunction, like Trisomy 21 (Down’s Syndrome)?

26. Category 3 10 Why is Karyotyping only used to identify genetic diseases caused by nondisjunction, like Trisomy 21 (Down’s Syndrome)? Karyotyping only allows you to count the number of chromosomes, not identify the genes.

36. Category 4 10 A pedigree indicates how a trait is passed through the family. Which is a pedigree?

37. Category 4 10 A pedigree indicates how a trait is passed through the family. Which is a pedigree? The left is a pedigree, the right is a karyotype

40. Category 4 30 If a trait is intermediate (not dominant or recessive) and they hybrid it a blending of the traits, it is said to be Co-codominanat Incomplete dominance

41. Category 4 30 If a trait is intermediate (not dominant or recessive) and they hybrid it a blending of the traits, it is said to be Co-codominanat Incomplete dominance

42. Category 4 40 How is polygeneic inheritance different from Mendelian?

43. Category 4 40 In Mendelian inheritance there is only dominant and recessive alleles for a single gene. In polygenic, there are 2 or more genes that control the trait.
