sexual reproduction & asexual reproduction

Question 1

Asexual reproduction (def.)

Answer 1

the process resulting in the production of genetically identical offspring from one parent. (no fusion of egg and sperm)

Question 2

advantages of asexual reproduction

Answer 2

Eliminates need to find a mate
Allows population to perpetuate itself if its individual members are isolated from one another
Permits organisms to multiply quickly without spending time or energy producing sperm and eggs

Question 3

disadvantages of asexual reproduction

Answer 3

Produces genetically identical offspring, which limits a population’s chances of surviving periods of drastic environmental change (same lack of advantageous traits in all individuals)

Question 4

Sexual reproduction (def.)

Answer 4

the process involving the fusion of nuclei to form a zygote and the production of genetically dissimilar offspring.

Question 5

Budding (def.)

Answer 5

produces offspring by the outgrowth and eventual splitting off of a new individual from the parent

Question 6

Fission (def.)

Answer 6

a parent separates into two or more offspring about equal size

Question 7

Fragmentation and regeneration (def.)

Answer 7

fragmentation is the breaking of a parent body into several pieces and regeneration is the regrowth of lost body parts

Question 8

reproducing sexually and asexually (answering technique)

Answer 8

Reproduce by asexual means when environmental conditions are favourable for faster reproduction of offspring
Reproduce sexually when conditions are not favourable, so as to increase genetic variation for better adaptation to drastic environmental changes
