Reproduction BIO 1100 Exam Questions
With Verified Answers
\.why do organisms have a reproductive system?
to pass on traits and keep their organism from dying out
\.asexual reproduction
results in generation of genetically identical offspring
\.asexual reproduction advantages
quicker, simpler, conserves energy
\.asexual reproduction costs
lack of genetic variation
\.where does asexual reproduction make sense?
in isolated and very stable environments
\.sexual reproduction
results in generation of genetically unique offspring
\.sexual reproduction advantages
diversity, mutation of alleles
\.sexual reproduction disadvantages
energy intensive, time, effort
\.when does sexual reproduction make sense?
less stable environments with large populations
\.what are the four types of asexual reproduction seen in animals?
, fragmentation and regeneration, fission, budding, parthogenesis
\.what is gametic meosis?
animals reproduce sexually, diploid gonads create haploid gametes which then go through
fertilization
\.what does oogamous mean?
female gamete is larger and immobile, male gamete is smaller and motile (different gametes)
\.gonads
organs that make gamete cells
\.copulation
sex; sexual contact of male and female
\.fertilization
union of haploid gametes to produce diploid zygote
\.external fertilization
timing and communication
\.internal fertilization
more specialized, gonads and accessory organs for copulation
\.unisexual organisms
only produce male or female gametes, not both
\.hermaphrodictic
expression of both male and female gametes
\.when is it beneficial to be hermaphroditic?
with low motility or low population
\.testicle
contains scrotum and testis
\.scrotum
pouch of skin outside abdomen that houses testis to maintain temperature needed for
spermatogenesis
