Is this topic sentence clear enough? Or is it too broad? If so, could I get some guidance, Im lost. This is for a comparaison/contrast paragraph.

"To share the same blood type and genetic material does not ensure that two people will be exactly alike, as it is true for my sister and I."

Do you mean a topic sentence (for one paragraph)? Or do you mean a thesis statement (for an entire paper or essay)?

As a topic sentence, this is fine. (It wouldn't be for a thesis statement, though.)

Its only a paragraph assignment so it only needs a topic sentence. What I was wondering was if I need to include the points of comparison in the topic sentence.

No, you don't need to. Those points of comparison will show up clearly in your paragraph if you organize it carefully. Your sentence is fine!

The topic sentence you provided is clear and specific enough for a comparison/contrast paragraph. It effectively introduces the idea of exploring how being related by blood and genetics does not guarantee that two individuals will be identical, using the example of you and your sister.

To further guide you in constructing a comparison/contrast paragraph, here are a few steps to consider:

1. Identify the specific points of comparison: Determine the specific aspects or characteristics that you will compare and contrast between you and your sister.

2. Organize your paragraph: Decide on an organizational structure for your paragraph. You could choose to alternate between discussing similarities and differences, or you could focus on each aspect separately.

3. Provide supporting details: Once you have identified the points of comparison and decided on the structure, provide specific examples or evidence to support each point. These examples can be personal experiences, observations, or research findings.

4. Analyze and explain the significance: After presenting your supporting details, analyze and explain the significance of the similarities and differences. What do these differences or similarities suggest about the influence of genetics and blood type on individual traits or characteristics?

5. Use transitional words or phrases: Remember to use appropriate transitional words or phrases to guide your reader through the comparison/contrast process. These can include words such as "similarly," "in contrast," "on the other hand," etc.

By following these steps, you can effectively develop a comparison/contrast paragraph that addresses the topic presented in your sentence.
