reproductive success
the ability to produce fertile offspring.
biological fitness
measure of reproductive success
biological fitness (alleles)
the average contribution to the gene pool by a certain genotype
asexual reproduction
involves one parent and gives rise to offspring that are genetically identical to the parent and other offspring.
sexual reproduction
involves two parents who produce offspring by a mixture of both parents genes
what are the different ways that asexual reproduction can occur?
fission, budding, fragmentation, spore formation, vegetative reproduction, and parthenogenesis.
how does asexual reproduction happen?
cell division process of mitosis.
what are the only sources of genetic variations in asexual reproduction?
mutations
binary fission
a parent cell replicating their dna and then splitting into two. sometimes multiple fission can occur (more than two cells) the cells are identical to the parent
budding
the growth of an organism from the body of a parent. the division of the cutoplasm is unequal. the new organism is a lot smaller than the parent.
fragmentation (or regeneration)
the seperation of the organism into at least two parts, both parts being capable of growing into a full organism.
spore formation
the production of tiny, unicellular cells that are produced in large numbers distributed over large distances.
