Eukaryote Reproduction Strategies Flashcards
Budding
Grow a copy
Parthenogenesis
Genetically identical eggs created asexually, mom clone
Isogamy
same gametes, no difference between sexes
FUNGI
Anisogamy
different gametes for sexes
Sperm vs egg
Most sexual reproduction
Plant and animal
Biological sexes produce different gametes
Diplontic
sexual life cycle: only eggs and sperm haploid
most animals
Alternation of Generations
multicellular haploid and diploid stages
plants
Haplontic
Only zygote is diploid
Fungi and some others
Monoecious Hermaphrodites Simultaneous
Both ovary and testes are present in the same individual (Bay scallop!)
Monoecious Hermaphrodites Sequential
start as one sex then transition to other depending on environmental conditions or social conditions
Dioecious
organism has either testes or ovaries
Asexual Reproduction
Genetic copies, sustainable, no resplicing of chromosomes
Self Fertilization
leads to reduced heterozygotes: decrease in genetic diversity
Increase in homozygote
