Front 1

Genetic diversity can arise from random changes in the DNA sequence called:

If a mutation occurred and the mutant allele had the same meaning as the original allele then:

Back 2

All of the statements are correct

Hint 2

The mutant allele's funciton would be the same as the original allele's function

The average correlation between IG of parents and their children is 42%. This means 42% of the variation among individual's IG are explained by the variation amont their parents' IG. This statement can be interpreted to mean:

Back 7

42% of variations are due to genetics and 58% are due to environment.

Front 8

If height is a highly heritable trait and variation is due to genes then one would expect:

Back 8

That identicle twins are closer in height to each other than fraternal twins to each other

Front 9

Maze-bright mice are better at running mazes than maze-dull mice. You take a group of mice that are maze-bright and a group of mice that are maze-dull and place the two groups in an enriched enviornment. The results show that both froups complete the mazes in better time than the same type of mice in a normal environment, but the maze-bright mice were still faster than the maze-dull mice. hese results tell you:

Back 9

The variations between mice groups are due to genes and enviornment.

Front 10

An individual has been told that they hve a malignants tumor. This means:

Back 14

Biopsy

Front 15

A person is considered to be in remission after _ years of being cancer free.

Back 15

5

Front 16

Meiosis results in the production of:

Back 16

Gametes

Front 17

Humans have:

Back 17

22 pairs of autosomes and 1 pair of sex chromosomes

Hint 17

autosomes/ sex chromosomes

Front 18

Homologous pairs of chromosomes:

Back 18

have the same genes but may have different alleles

Hint 18

genes and alleles?

Front 19

Segments of DNA that carry information about traits are called:

Back 19

Genes

Front 20

An organism's full set of chromosomes is/are called its:

Back 20

Genome

Front 21

what statement is not correct about genes

Back 21

All are correct

Hint 21

A gene is a sequence of DNA

Genes are composed of DNA

Genes encode for proteins

Genes are located on Chromosomes

Front 22

The process that converts the instructions of DNA into the message of RNA is called:

Back 22

Transcription

Front 23

Which is not a way RNA differs from DNA

Back 23

RNA is double stranded

Hint 23

RNA contains a ribose sugar

RNA is double stranded

A hydrogen binds to U

RNA is single stranded

RNA contains the base uracil instead of thymine

Front 24

What is the correct order of protein synthesis

Back 24

DNA -> mRNA -> amino acids -> protein

Front 25

The ABO blood system has two dominant alleles and one recessive allele. The three possible alleles for blood type are an example of:

Back 25

Multiple allelism

Front 26

A woman with blood type A, whose father has blood type O, has a child with a man whos blood type is AB. What is the probablility of this couple having a child with blood type O?

Back 26

0%

Front 27

Brown eyes are dominant to blue eyes, curly hair is dominant to straight hair, and wavy hair is a reslut of incomplete dominance. What would be the phenotype of a child whose parents were CCBB x ccbb cross?

Back 27

Wavy hair, brown eyes

Front 28

Sex determination involves the:

Back 28

x and y chromosomes

Front 29

Males are more suceptible to X linked traits because:

Back 29

Males only have one X and thus express whatever is on that single X chromosome

Front 30

A person who expresses the normal phenotype but has a heterozygous genotype for a recessively inherited disorder, such as cystic fibrosis, is said to be a _ for the trait.

Back 30

Carrier
