Types Of Reproduction

Question 1

What is asexual reproduction?

Answer 1

A process by which a single parent produces offspring that are genetically identical to itself.

Question 2

What is sexual reproduction?

Answer 2

A process that involves the fusion of male and female gametes to produce genetically different offspring.

Question 3

True or False: Asexual reproduction involves the fusion of gametes.

Answer 3

False

Question 4

What are the advantages of asexual reproduction?

Answer 4

Rapid reproduction, no need to find a mate, and all offspring are genetically identical.

Question 5

What are the disadvantages of asexual reproduction?

Answer 5

Lack of genetic diversity, vulnerability to diseases, and limited adaptation to changing environments.

Question 6

What is fragmentation?

Answer 6

A form of asexual reproduction in which an organism is divided into pieces, each of which can grow into a new organism.

Question 7

What is a gamete?

Answer 7

A specialized reproductive cell that fuses with another gamete during fertilization in sexual reproduction.

Question 8

What is the male gamete in humans?

Answer 8

Sperm

Question 9

What is the female gamete in humans?

Answer 9

Egg (ovum)

Question 10

What is fertilization?

Answer 10

The fusion of a male gamete (sperm) with a female gamete (egg) to form a zygote.

Question 11

What is a zygote?

Answer 11

A fertilized egg cell formed by the fusion of male and female gametes.

Question 12

How many chromosomes do human gametes contain?

Answer 12

23 chromosomes

Question 13

What is genetic variation?

Answer 13

Differences in the genetic makeup of individuals within a population.

Question 14

How does sexual reproduction contribute to genetic variation?

Answer 14

By combining genetic material from two different individuals to produce offspring that is genetically different from both parents

Question 15

What is cross-pollination?

Answer 15

The transfer of pollen from the male reproductive organ of one plant to the female reproductive organ of another plant.

Question 16

What is the advantage of farmers reproducing fruits asexually?

Answer 16

It allows for the production of genetically identical offspring. Since a single parent forms a genetically identical clone of it self by mitosis, causing it to be beneficial economically wise for the farmers.

Question 17

What are advantages of sexual reproduction

Answer 17

Increase genetic variation. Species can adapt to new environments due to variation. Disease is less likely to affect the population due to genetic variation.

Question 18

What are disadvantages of sexual reproduction

Answer 18

Takes time to find mates. Difficult for isolated members (since they have adapted to new environments) of the same species to reproduce

Question 19

Process of sexual reproduction

Answer 19

Involves the genes/chromosomes from 2 parents.

Meiosis occurs to form gametes then these gametes fertilize.

After fertilization, mitosis increases the cell number for growth, development.

Offspring that is produced is genetically different from both parents, this happens because the genetic info. from each parent is found in the gametes, and during fertilization the gametes join together which causes a mixing of genes to take place, forming a fetus.

Question 20

Process of asexual reproduction

Answer 20

Includes one parents genes.

Parent makes a genetically identical clone of itself using mitosis.

So the offspring produced only has DNA from one parent. Causing the offspring to be identical to the parent.

Variation may occur due to mutations or environmental factors.

Question 21

What is genotype?

Answer 21

Genotype is the genetic makeup of an individual which determines particular characteristics.

Question 22

What is phenotype

Answer 22

The physical expression of genes. (blue/green eyes)

Question 23

Homozygote

Answer 23

When both genes are the same

Question 24

Heterozygote

Answer 24

When both genes are different

Question 25

Explain sexual reproduction in flowers

Answer 25

Flowers make male pollen and female ovule gametes by meiosis.
The pollen of one flower pollinates the ovule of another flower.
New seeds are produced to make new plants.
