B10 Reproduction Flashcards
define asexual reproduction
process resulting in the production of genetically identical offspring from one parent
advantages of asexual reproduction of the species in the wild (4)
only one parent needed
fast
less energy needed
less time needed
rapid colonization
disadvantages asexual reproduction of the species in the wild (4)
no genetic variation
overpopulation
less able to adapt to changes
competition due to overcrowding
the whole population can be affected from a disease
example species that does asexual reproduction (4)
bacteria, fungi, plant, hydra
define sexual reproduction
the process involving the fusion of the nuclei of two gametes to form a zygote and the production of offspring that are genetically different from each other
nuclei of gametes are ……. while the nucleus of a zygote is ……
haploid (23) diploid (46)
advantage of sexual reproduction to a species in the wild (2)
genetic variations
can adapt to changes
sexual reproduction advantages in the wild (3)
genetic variation
can adapt to changes
only some individuals affected by the disease
sexual reproduction disadvantages in the wild (2)
two parents needed
more energy needed
time consuming
