Asexual and Sexual Reproduction Flashcards
Studying for the test on Asexual and Sexual Reproduction
What are the pro’s of sexual reproduction
-More genetic diversity
-Less likely to be wiped out by rapid change in environment
-Better able to adapt to changes in environment
What is a feature about Sexual Reproduction?
-Requires fertilization
-Requires 2 parents
-Offspring have a combination of parents genes
Process whereby a single celled organism divides asexually to produce two daughter cells
Binary Fission
Thread like structure composed of DNA and proteins found in the nucleus of a cell
Chromosome
growth of an organism from an unfertilized gamete, or sex cell
Parthenogenesis
How is sexual and asexual reproduction different
Sexual reproduction requires two parents while Asexual reproduction requires one parent
What are some pros of asexual reproduction
-Faster reproduction rates
-Less energy required
-No mate necessary
Segment of DNA that contains instructions for building and maintaining an organism
Gene
What are some examples of organisms that uses sexual reproduction
-Humans
-Plants
-Animals
-Fungi
How is sexual and asexual reproduction the same
They are both ways the organisms can reproduce
What is a feature between asexual reproduction
-Does not require fertilization
-Offspring are genetic copies of the parent
Difference in DNA sequence among individuals within a population or species
Genetic Variation
Reproduction of an offspring from two parents
Sexual Reproduction
Cell division that results in the formation of two genetically identical daughter cells, each with the same number of chromosomes as the parent cell
Mitosis
What are some cons of asexual reproduction
-No genetic diversity
-Can be wiped out by rapid change to the environment (Disease that kills one would kill all)
- Can result in overcrowding rapidly
