Step-by-step solution for: Genetics Vocabulary | Lecture notes Genetics | Docsity
Let's solve this genetics vocabulary worksheet step by step using the word bank provided.
---
different, two, both, progeny, prevents, events, code, cross, trait, homozygous, ABO, offspring, genes, expresses, single, many, number, physical, combinations, producing, neither, identical, gamete, independently
---
Now, let’s fill in each blank with the correct word from the word bank. We'll go one by one and explain the reasoning.
---
- A hybrid is an organism that has two different alleles for a trait (one from each parent).
- Example: If one parent gives allele "A" and the other gives "a", the hybrid genotype is "Aa".
- ✔ Correct answer: different
> Answer: different
---
- This definition is complete. No blank here.
- Just note: dominant alleles express their trait even if only one copy is present.
> No answer needed
---
- Genes are segments of DNA that code for proteins or traits.
- The word "code" fits perfectly here — genes code for traits.
- ✔ Correct answer: code
> Answer: code
---
- This definition is complete. No blank.
- Example: For eye color, alleles might be blue or brown versions of the same gene.
> No answer needed
---
- Heredity refers to how traits are passed from parents to their children.
- The term offspring is used for the children or next generation.
- ✔ Correct answer: offspring
> Answer: offspring
---
- This definition is complete.
- Purebreds are homozygous for certain traits due to consistent breeding.
- But no blank — just understanding.
> No answer needed
---
- Traits are passed via genes.
- Genes are inherited from parents and determine traits.
- ✔ Correct answer: genes
> Answer: genes
---
- Definition is complete.
- No blank.
> No answer needed
---
- Probability is a number between 0 and 1 (or percentage) indicating likelihood.
- It describes the chance of an event happening.
- ✔ Correct answer: number
> Answer: number**

1. Hybrid – An organism that has two different alleles for a trait.
3. Gene – The set of information that controls a trait; codes in the DNA.
5. Heredity – The passing of traits from parents to offspring.
7. Trait – A characteristic that an organism can pass to offspring through genes.
9. Probability – A number that describes how likely it is that an event will occur.

1. Hybrid - An organism that has two _____________ alleles for a trait.
- A hybrid is an organism that has two different alleles for a trait (one from each parent).
- Example: If one parent gives allele "A" and the other gives "a", the hybrid genotype is "Aa".
- ✔ Correct answer: different
> Answer: different
---
2. Dominant - An allele whose trait always shows up in the organism when it is present.
- This definition is complete. No blank here.
- Just note: dominant alleles express their trait even if only one copy is present.
> No answer needed
---
3. Gene - The set of information that controls a trait; _____________ in the DNA.
- Genes are segments of DNA that code for proteins or traits.
- The word "code" fits perfectly here — genes code for traits.
- ✔ Correct answer: code
> Answer: code
---
4. Alleles - The different forms of a gene.
- This definition is complete. No blank.
- Example: For eye color, alleles might be blue or brown versions of the same gene.

5. Heredity - The passing of traits from parents to _____________.
- Heredity refers to how traits are passed from parents to their children.
- The term offspring is used for the children or next generation.
- ✔ Correct answer: offspring
> Answer: offspring
---
6. Purebred - The offspring of many generations that have the same traits.
- This definition is complete.
- Purebreds are homozygous for certain traits due to consistent breeding.
