| Question | Answer |
| Inheritance | How traits or characteristics are passed on from generation to generation. |
| Allele | A variation of the gene for a particular trait/characteristic |
| Gene | A section of DNA that codes for a protein |
| Phenotype | The observation characteristics of an organism, it's appearance. Eg. tall, short, round, etc. Remember to say percentage. Eg. 100% brown eyes or 75% long arms, 25% short arms. |
| Genotype | The set of genes in our DNA which is responsible for a particular trait. The genetic makeup of an individual. Eg. 100% Bb or 75% BB, 25% Bb. |
| Dominant Allele | The characteristic always seen in the offspring. It always overpowers the other allele. Eg. If B=brown eyes & b=blue eyes than B is dominant (capital letter) If someone had a genotype of Bb the person would have brown eyes but carry a recessive gene. |
| Recessive Allele | The characteristic masked by a dominant one. - Lower case letter - Has to have 2 recessive alleles to show (eg. bb = blue eyes but Bb = brown eyes) |
| Heterozygous | Having two different kinds of allele. (Eg. Bb, eE, Gg, Yy, etc.) |
| Homozygous | Having the same alleles for a particular characteristic. Eg. TT, bb, ee, GG, PP, etc. |
| Monohybrid Genetics | Looking at how 1 trait (characteristic) is passed on to the next generation. It always has a dominant and recessive gene. |
