Questions and Answers

Which process involves the production of genetically identical offspring by mitosis?

  • Fertilization
  • Sexual reproduction
  • Meiosis
  • Asexual reproduction (correct)

What is the difference between asexual and sexual reproduction?

  • Asexual reproduction results in a generation-to-generation sequence of stages, while sexual reproduction does not

  • Asexual reproduction requires two parents, while sexual reproduction only requires one parent
  • Asexual reproduction involves the fusion of gametes, while sexual reproduction does not

What is a clone?

  • Offspring with unique combinations of genes inherited from both parents
  • The generation-to-generation sequence of stages in the reproductive history of an organism

Study Notes

Reproduction

  • Asexual reproduction involves the production of genetically identical offspring by mitosis, where a single parent cell divides into two or more daughter cells with identical genetic material.
  • Sexual reproduction, on the other hand, involves the fusion of gametes from two parents to produce offspring with a unique combination of genetic traits.

Cloning

  • A clone is an organism that is genetically identical to another organism, produced through asexual reproduction.

Chromosomes

  • Autosomes are non-sex chromosomes, which are chromosomes that are not involved in determining the sex of an organism.
  • Human somatic cells have 46 chromosomes, arranged in 23 pairs.
