B6- Reproduction

Question 1

What is sexual reproduction?

Answer 1

The combination of genetic information from two organisms to produce genetically different offspring

Involves a father and a mother producing gametes through meiosis.

Question 2

What are gametes?

Answer 2

Reproductive cells produced by meiosis, such as egg and sperm cells in animals

Each gamete contains half the number of chromosomes of a normal cell.

Question 3

How many chromosomes does each gamete contain?

Answer 3

23 chromosomes

This is half the number of chromosomes found in a normal somatic cell.

Question 4

What happens during fertilization?

Answer 4

The egg and sperm cells fuse together to form a fertilised egg with a full set of chromosomes

This includes half from the father and half from the mother.

Question 5

What is the result of sexual reproduction in terms of genetic variation?

Answer 5

Offspring inherit a mixture of genes from both parents, leading to genetic variation

The chromosomes inherited from each parent influence the traits of the offspring.

Question 6

What is asexual reproduction?

Answer 6

A type of reproduction involving only one parent, resulting in genetically identical offspring

Offspring are clones of the parent.

Question 7

How does asexual reproduction occur?

Answer 7

Through mitosis, where an ordinary cell divides to produce a new cell

This new cell has the same genetic information as the parent cell.

Question 8

What are clones?

Answer 8

Offspring that are genetically identical to the parent

In asexual reproduction, the offspring are clones.

Question 9

What is a key characteristic of asexual reproduction?

Answer 9

No fusion of gametes, no mixing of chromosomes, and no genetic variation

The offspring are genetically identical to the parent.

Question 10

Which organisms typically reproduce asexually?

Answer 10

Bacteria, some plants, and some animals

Asexual reproduction is common in unicellular organisms and certain multicellular organisms.

Question 11

Fill in the blank: In sexual reproduction, the offspring inherits features from both parents because it receives a mixture of _______.

Answer 11

chromosomes

Question 12

True or False: Asexual reproduction produces genetically diverse offspring.

Answer 12

False

Asexual reproduction results in offspring that are clones of the parent.

Question 13

What is the role of pollen in flowering plants?

Answer 13

Pollen serves as the male gamete in the reproduction process

Egg cells in plants are analogous to egg cells in animals.
