Chapter 1-Genes

Question 1

What is DNA?

Answer 1

DNA is the carrier of genes,it defines what your characteristic is

Answer 2

DNA is located in the cell membrane

Question 3

What is inside the nucleus?

Answer 3

Inside the nucleus there is DNA in the form of a chromosome

Question 4

What is a dominant alleles?

Answer 4

A dominant alleles only needs one of the characteristic to be present

Question 5

What is a recessive alleles?

Answer 5

A recessive alleles needs two of the same gene to be present

What is the Capital Letter in genes/characteristic

Answer 6

The large letter is dominant

Question 7

Question 14

A name of an inherited disorder

Answer 14

Cystic Fibrosis

Question 15

What is cystic fibrosis

Answer 15

Cystic fibrosis produces lots of sticky mucus in the oesophagus making it difficult to breath this is a recessive alleles

Question 16

What is Polydactyl

Answer 16

Polydactyl is a disease that makes a human being have an extra digit on their hands or feet/ this is a dominant alleles

Question 17

What is variation

Answer 17

Variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors

Question 18

Chromazome

Answer 18

A Chromosome is carrying genetic information in the form of genes

Question 19

What is selective breeding

Answer 19

Selective breeding is a specific type of breeding chosen by humans

Question 20

Sexual Reproduction

Answer 20

the production of new living organisms by combining genetic information from two individuals of different types (sexes).

Question 21

Asexual reproduction

Answer 21

Is when only one of the parents is needed to breed

Question 22

What is clone

Answer 22

A clone is a asexually bread animal in which it is identical to it’s ancestor

Question 23

What is genetic engineering

Answer 23

Genetic Engineering involves changing the genetic material of on organism. You cut a gene from one organism using enzymes. Then transfer it to a gene of a completely different organism.

Question 24

What is environmental variation?

Answer 24

Environmental variation are certain traits that aren’t inherited and are caused by the environment, for example the length of your hair, tattoos or your weight

Question 25

Out of brown and blue eyes, which is dominant and which is recessive?

Answer 25

Brown is dominant and blue is recessive.

Question 26

Is the polydactyl cell dominant or recessive?

Answer 26

Dominant

Question 27

Is cystic fibrosis dominant or recessive?

Answer 27

Recessive

Question 28

What would the ratio for dominant to recessive be for the parents Bb x Bb?

Answer 28

3:1 (75%)

Question 29

What does it mean to be a carrier of a disorder?

Answer 29

With a disorder like cystic fibrosis where the allele is recessive, if you have one dominant and one recessive you are a carrier of the gene. You cannot be a carrier of polydactyl as it is a dominant allele.

Question 30

What is a punnet square?

Answer 30

A punnet square is a genetic diagram showing the probability of the different outcomes for your offspring based on your alleles.

Question 31

What is love?

Answer 31

Baby don’t hurt me
