Reproductive Biology: Asexual and Sexual Reproduction

These flashcards cover key concepts related to asexual and sexual reproduction, including definitions, advantages, disadvantages, and reproductive anatomy.

What are the advantages of sexual reproduction?

Prevention of disease, genetic variation, and species development to the environment due to survival advantage.

What are the disadvantages of sexual reproduction?

More mutations, longer time to reproduce, and requires more energy.

What are the advantages of asexual reproduction?

Fast reproduction and doesn't require much energy.

What are the disadvantages of asexual reproduction?

Easy to go extinct due to lack of variation, potential for overpopulation, and increased competition.

What is asexual reproduction?

Reproduction involving one parent, producing clones through processes like budding, fission, and fragmentation.

What are the main processes of asexual reproduction?

Budding, fission, and fragmentation.

Define sexual reproduction.

The creation of a new organism through genetic recombination of two individuals of different sexes.

What are gametes?

Specialized sex cells for reproduction, specifically sperm and egg.

What is a zygote?

The fertilized egg that develops into an individual from the union of sperm and egg.

What is the difference between haploid and diploid?

Haploid cells have 23 chromosomes; diploid cells have 46 chromosomes.

What is live birth?

When an organism gives birth to a living offspring.

Define egg-laying.

When an organism lays an egg that has not yet hatched.

What are the primary male reproductive organs?

Testes, scrotum, and penis.

What are the primary female reproductive organs?

Ovaries, cervix, and vagina.

How does fragmentation occur in asexual reproduction?

An organism splits into fragments, each developing into a fully mature adult.
