Final Jeopardy

I am seen as the father of heredity and genetics with my experiments on pea plants.

2

Who is Gregor Mendel

3

4

Mendel did research on this --- the Mendel did research on this --- the transmission of characteristics transmission of characteristics from parent to offspringfrom parent to offspring

5

What is Heredity?

6

Mendel obtained pure Mendel obtained pure parent pea plants by doing parent pea plants by doing this a form of reproduction this a form of reproduction with only one parent. with only one parent.

7

Asexual reproduction.

8

Mendel’s first experiments were crosses that involved only one type of characteristic. These type of crosses are know as?

9

What are monohybrid ?

10

.Name and describe the 3 types of mutations.

11

A deletion is when a base is completely left out. 2. When an extra base is added inthis is called a insertion 3. When the wrong base is usedthis is called substitution. This is the most common mutation.

12

The two different versions of a gene.

13

What are alleles?

14

In a Punnett square a lowercase letter represents

15

A recessive trait

Bonus:

16 The trait that was not or is not expressed when a characteristic is present.

17

What is a recessive trait

18

the set of alleles that an individual has for a characteristic.

19

What is genotype

Bonus:

20

Adenine and guanine are double ringed bases. These are called

21

What are purines?

22Genotype referred to as being Genotype referred to as being “Pure”. This occurs when “Pure”. This occurs when there are crosses between either there are crosses between either two dominant or two recessive two dominant or two recessive traits traits

23

What is a homozygous trait

Bonus:

24

The physical appearance of a characteristic in an organism.

25

What is phenotype

26Chargaffs rule stated .

27

Adenine in DNA always equals the amountthymine. And amount of guanine always equals the amount of cytosine.

28

the double helix must “unzip” and an identical copy of nitrogen bases must be produced this process is called

29

DNA Replication

Bonus:

30

Inside chromosomes lies this genetic information needed to copy a cell.

31

What is DNA?

Bonus:

32

These are said to be hybrids. In which the crosses gives you one dominant and one recessive allele.

33

What is a heterozygous trait?

34

They often prepare pedigrees for families that show how a trait is passed through several generations.

35

What is a geneticist?

36

What are the 3 parts to to a DNA molecule ?

37

1. A sugar 2. A phosphate 3. A nitrogen base

38

Changes in the number, order, or type of bases on a piece of DNA are known as

39

What are mutations?

Bonus

40

In humans there are ___ number of sex chromosomes

41

What is 23?

42During meiosis, each sex cell receives only one chromosome for gender from each parent cell.

In males there are ___

In females there are ________

43

Males have X and YFemales have X and X

44Subunits of DNA that are comprised of a sugar, phosphate, and a nitrogen base

45

What is a nucleotide

Bonus:

46

Cytosine and thymine are single rings and called

47

What are pyrimidines

40

In some organisms an individual may display a phenotype that is intermediate between the two parents

49

Incomplete dominance

50

DNA is in the shape of a ____________. (spiral staircase)

51

What is a double helix?

52

How much are

   you willing to wager? Discuss

with your group

What are the phenotypes if you have a homozygous parent for dominant red and a heterozygous plant with a red color.

53Answer may vary
