Genetics
Review terms for genetics
| Question | Answer |
|---|---|
| what is a gene | segments of DNA found in a chromosome that give instructions for producing a certain characteristic |
| Different versions of a gene are known as | alleles |
| Genotype | the combination of alleles that you inherited from your parents |
| Your observable traits | Phenotype |
| Dominant allele | Determines the phenotype if one or both copies of the allele are present |
| Recessive | determines phenotype only when two copies of the allele are preseent |
| The passing of genetic material from parents to offspring | Heredity |
| Incomplete Dominance | each allele in a heterozygous individual influences the phenotype |
| Codominance | Both of the alleles in a heterozygous individual contribute to the phenotype. |
| Heterozygous | having both the dominant and recessive copies of the allele |
| Homozygous | having two copies of either the dominant or recessive copies of an allele |
| Hh | this allele is heterozygous |
| HH, hh | this allele is homozygous |
