Inheritance, Variation And Evolution

Question 1

What does meiosis cell division produce ?

Answer 1

Gametes

Question 2

What cells does meiosis produce ?

Answer 2

Non identical cells so every sperm and egg cell are different

Question 3

Where else does meiosis also take place ?

Answer 3

in plants

Question 4

What are the gametes in plants ?

Answer 4

Pollen and egg cells

Question 5

What reproduction do animals and plants do ?

Answer 5

Sexual reproduction

Question 6

What does sexual reproduction involve in the human ?

Answer 6

The fusion of male and female gametes e.g the sperm cell and egg cell

Question 7

Whats the process called when the gametes fuse together ?

Answer 7

Fertilisation

Question 8

What happens in sexual reproduction ?

Answer 8

The mixing of genetic material

Question 9

What does the mixing of genetic material mean ?

Answer 9

The offspring will receive genetic information from both male and female parents

Question 10

Why is there variation in offspring ?

Answer 10

Because every gamete is different

Question 11

How many parents are there in asexual reproduction ?

Answer 11

Only 1

Question 12

What does asexual reproduction not involve and why ?

Answer 12

Gamete because they’re is only one parent so no mixing of genetic material is required

Question 13

Whats different about the offspring in asexual reproduction ?

Answer 13

They are all identical ?

Question 14

Whats it called when the offspring are identical in asexual reproduction ?

Answer 14

Clones

Question 15

Why does meiosis not take place in asexual reproduction ?

Answer 15

Because they’re are not gametes due to one parent

Question 16

Where are chromosomes found ?

Answer 16

In the nucleus of cells

Question 17

What do chromosomes contain ?

Answer 17

DNA

Question 18

The does your DNA determine ?

Answer 19

Two strands

Question 20

What is each strand called in DNA ?

Answer 20

Polymer

Question 21

How is each strand made ?

Answer 21

By joining together lots of smaller molecules

Question 22

Whats it called when the two strands wrap around each other ?

Answer 22

A double helix

Question 23

Whats a gene ?

Answer 23

Small section of DNA on a chromosomes

Question 24

How are proteins made ?

Answer 24

By joining together amino acids

Question 25

What does each Gene have ?

Answer 25

A specific sequence of amino acids to make a protein

Question 26

Whats the same about the chromosome pairs ?

Answer 26

Both chromosomes in a pair have the same genes

Question 27

Whats the genome ?

Answer 27

The entire genetic material that’s makes a organism

Question 28

Whats the human genome ?

Answer 28

The entire genetic information that makes a human

Question 29

What are the benefits of scientists being able to have studied the whole human gnome ?

Answer 29

Helps us to search for genes that are li led to diseases such as Cancer or Alzheimer’s disease

Helps us to understand and treat inherited disorders such as cystic fibrosis

Helps us discover ancestry

Question 30

Whats the problem with Darwin’s theory of evolution ?

Answer 30

It challenges the belief of god
