variation and continous and discontinous

Answer 1

They are the characteristics that defer between the same species and different species.

1- Genetic
2- Environmental
3- Both genetic and environmental

Question 3

Answer 5

Blood types
Eye colour

Question 6

Give examples of environmental variation

Answer 6

Hair length
Accent
Tattoos, piercings,scars

Question 7

Give examples of variations caused by both inheritance and environmental

Answer 7

1- Weight
2- Height
3- Skin colour

Question 8

What do alleles give us different

Answer 8

characteristics

Question 9

What are the 2 types of variation

Answer 9

1-Intraspecific variation
2- Interspecific variation

Question 10

Define intraspecific variation

Answer 10

Variations within species

Question 11

Define interspecific variation

Answer 11

Variations between species

Question 12

Give 1 example of intraspecific variation

Answer 12

Hair length of different dogs

Question 13

Give 1 example of interspecific variation

Answer 13

Hair length of different mammals

Question 14

What are inherited characteristics

Answer 14

They are passed down from our parents. We are born with them and they are found in our genes with are part of the DNA found in the nucleus of our cells.

Question 15

True or false

Answer 15

We get half our characteristics from our dad and the other half from our mother

Question 16

What are enviromental charesterstics

Answer 16

They are the charecteristics that are detremined by how we love and the action we do.

Question 17

What is the other classification for different types of variation

Answer 17

1- Continuous and discontinuous

Question 18

Give the 5 features of discontinuous variation

Answer 18

1- Caused by genes only
2- Always a bar chart ( with gaps in between the bars)
3- Doesn’t include numbers ( qualitative)
4- Can only be of few groups: Males and females
5- Examples: Eye colour and Blood group

Question 19

Give the 6 features of continuous variation

Answer 19

1- Include numbers ( quantitative)
2- Vary in range : 150.1,150.2 , etc…
3-Always a histogram ( the line goes through the middle with no gaps)
4- Don’t start from 0.
5- Caused by genes and environment.
6- Height in cm/ Weight in K.G

Question 20

Draw a rough sketch of how discontinuous and continuous data should look like

Answer 20

(check)

1- Continous should have gaps between the bars

2- Discontinous should have no gaps, a histogram connecting to the half and not start with 0

Question 21

True or false

Eye colour is an example of continuous variation:

Continuous variation is caused by genes only:

Continuous variation is drawn using a histogram:

Continuous variation is quantitative:

Discontinuous variation is caused by genes and the environment:

Height is an example of discontinuous variation:

Discontinuous variation is drawn on a bar chart:

Answer 21

Eye colour is an example of continuous variation: False

Continuous variation is caused by genes only: False

Continuous variation is drawn using a histogram: True

Continuous variation is quantitative: True

Discontinuous variation is caused by genes and the environment: False

Height is an example of discontinuous variation: False

Discontinuous variation is drawn on a bar chart: True
