Asexual vs Sexual Reproduction Flashcards
What is the primary goal of reproduction in living things?
To survive and pass on DNA
Reproduction is essential for the survival of species.
What does genetic continuity refer to?
Maintaining gene number and structure from one generation to the next
What are the two main forms of reproduction?
- Asexual reproduction
- Sexual reproduction
How is genetic continuity maintained in asexual reproduction?
By mitosis and cytokinesis
What occurs during mitosis and cytokinesis?
- One duplication and one division of DNA
- Results in two daughter cells genetically IDENTICAL to the parent
In which type of cells does mitosis and cytokinesis occur?
All somatic (body) cells except sex cells
What type of reproduction involves meiosis?
Sexual reproduction
What is the process of meiosis characterized by?
- One duplication and two divisions of DNA
- Results in four daughter cells genetically SIMILAR to the parent
- Daughter cells contain HALF the number of chromosomes
What ensures that the zygote formed during sexual reproduction has the same chromosome number and structure as the parents?
Reduction of chromosome number during meiosis

Fill in the blank: Sexual reproduction results in daughter cells that are _______ to the parent.
genetically SIMILAR
True or False: Asexual reproduction involves two divisions of DNA.
