| Question | Answer |
|---|---|
| What does heredity ? | passing traits from offspring |
| What are genetics ? | the study of heredity and variation in organisms |
| What is DNA? | a double stranded helical nucleic acid molecule that codes ans stores genetic information it determines the inherited structure of cells proteins |
| What are chromosomes? | thread like strands of DNA and protein in a cell nucleus that carry the code fr the inherited characteristics of an organism |
| What is a gene? | a distinct unit of hereditary material found in chromosomes the region of DNA that directs the making of a specific protein thus controlling traits that are passed in offspring |
| What is an allele? | different forms of a gene controlling a particular trait; e.g.,one allele fro height may be short while another allele may be tall |
| What is a dominant allele? | the from of a gene that appears to dominate or mask another form of the same trait the form of the allele that is most often expressed in the phenotype |
| What is a recessive allele? | the from of a gene that is often masked by the dominant allele and is therefore often not expressed in the phenotype |
