2 What type of gene causes traits that are less likely to occur?

3 WHAT IS A RECESSIVE GENE

4 Which of these is due entirely to inheritance in humans? a.Eye color b.Reading skill c.Endurance d.Broken bones

5 B- EYE COLOR

6 Calculate the number of cells that would exist if a cell underwent mitosis every 10 minutes for 1 hour.

7 What would be 64 cells Start with 1 First 10 minutes 2 Second 10 minutes 4 Third 10 minutes 8 Fourth 10 minutes 16 Fifth 10 minutes 32 Sixth 10 minutes (an hour) 64

8 Mendel’s early work with pea plants demonstrated a significant genetic discovery. The crossing of homozygous tall pea plants with homozygous short pea plants always resulted in tall plants and demonstrated that tallness in pea plants is a trait that is:

9 What is Dominant

10 A lizard re-growing a lost tail is an example of what?

11 What is Regeneration

12 New yeast grows on a parent yeast organism, and breaks off when it is ready to form a new separate organism. What type of reproduction is this an example of?

13 What is Asexual Reproduction

14 Which of the following traits of a dog is inherited from the parents? a.The presence of fleas in its fur b.The color of its fur c.The ability to sit up and beg d.The habit of barking to go outside

15 What is b- the color of its fur

16 Each form of a gene is called an allele. The alleles for human blood type are A, B, and O. Both the allele for type A blood and B blood type are dominant. The allele for type O blood is recessive. What blood type will a person if he inherits an allele for type A and an allele for type O?

17 What is type A

18 The chances of developing cancer, diabetes, or sickle-cell anemia are higher if a family member also has the disorder because they are - a.Highly infectious b.Passed through blood contact c.Genetically based d.Related to diet

19 What is C- genetically based

20 Why is DNA essential to living organisms?

21 What is it carries the genetic code

22 What type of gene causes traits that are more likely to occur?

23 What is a dominant gene

24 What are the possible genotypes of the offspring from a cross between two people with genotypes Bb?

25 What are X B b B b BB Bb bb

26 When a cell of a plant stem divides, each new cell has how many chromosomes?

27 What is the same number of chromosomes as the parent cell

28 The physical expression of a genetic trait is called what?

29 What is it’s phenotype

30 In humans, having bushy eyebrows is a trait that is dominant over having thin eyebrows. Two parents with bushy eyebrows are going to have a baby. What can be predicted about how the baby’s eyebrows will develop?

31 What is the baby most likely will have bushy eyebrows

32 I have green eyes and you might have brown eyes. Different eye color is caused by what?

33 What is different combinations of genes for eye color

34 In pea plants, purple flowers are dominant to white flowers. Suppose a purple flowered plant with genotype Pp is crossed with another purple flowered plant with the same Pp genotype. What percentages of offspring will also have purple flowers?

35 What is 75%

36 The allele for black hair, B is dominant to orange tabby color, b, in cats. Based upon the Punnett square below, what did the parents look like in this genetic cross? Bbbb Bbbb

37 What is one black parent Bb and one tabby parent bb

38 How much genetic material is found in a cloned cell as compared to the original cell?

39 What is the same amount?

40 Brown eyes are dominant to green/blue eyes. Both of my parents had brown eyes, but I had green eyes. What is the BEST explanation for why I have green eyes?

41 What is both of my parents carried a gene for green/blue eyes Bb

42 Poodles, like all dog breeds, are so closely related to wolves that they can breed with them. What is the best explanation for why wolves and poodles do not look alike, despite being extremely close relatives?

43 What is poodles are the result of people selectively breeding them for specific taits

44 What are the chances of having homozygous recessive offspring if the father is homozygous dominant for brown hair and the mother is heterozygous for brown hair?

45 What is 0% B B BBB bBb

46 What is true of the offspring of organisms that reproduce sexually?

47 What is they have some genetic traits of both parents, but are not exactly like either.

48 The process of an organism passing on its traits to its offspring is called what?

49 What is heredity

50 If you selectively breed two German Shepherds that are homozygous dominant for a trait. The resulting offspring will be examples of what?

51 What is a purebred
