Question

sexual vs. asexual reproduction
instructions:
a. classify and organize the cards into two categories: sexual vs. asexual reproduction. answer the following questions based on your classifications.

1. compare sexual vs. asexual offspring:
2. list 1 card that you classified as sexual reproduction.

explain why:

1. list 1 card that you classified as asexual reproduction.

explain why:

1. what are the advantages of sexual reproduction?
2. what are the disadvantages of asexual reproduction?

Explanation:

1. In sexual reproduction, offspring inherit a combination of genetic material from two parents, leading to genetic diversity. In asexual reproduction, offspring are genetically identical (uniform) to the single parent.
2. For example, if a card shows "dogs mating", it is sexual reproduction. Because it involves two parents (a male and a female dog) contributing genetic material through the process of fertilization.
3. If a card shows "bacteria dividing by binary fission", it is asexual reproduction. Binary fission is a form of asexual reproduction where a single - celled organism (like bacteria) divides into two identical daughter cells without the involvement of gametes or two parents.
4. Advantages of sexual reproduction include genetic diversity. This diversity helps populations adapt to changing environments (e.g., if a new disease emerges, some individuals with certain genetic variations may be resistant). It also provides the raw material for evolution.
5. Disadvantages of asexual reproduction: Lack of genetic diversity. If the environment changes (e.g., a new pathogen appears or a change in climate), the entire population (which is genetically uniform) may be at risk. There is less potential for adaptation compared to sexually reproducing populations.

Answer:

1. Sexual reproduction produces diverse offspring (due to genetic recombination from two parents), asexual reproduction produces uniform offspring (genetically identical to the single parent).
2. Example: Card with "human fertilization". Why: Involves two parents (sperm from male and egg from female) combining genetic material.
3. Example: Card with "amoeba splitting". Why: A single - celled organism (amoeba) reproduces by dividing into two identical cells (binary fission, a form of asexual reproduction).
4. Genetic diversity for adaptation and evolution.
5. Lack of genetic diversity, making populations more vulnerable to environmental changes.
