| Question | Answer |
|---|---|
| Actual genetic makeup | Genotype |
| chromosomes determining male/femaleness | Sex Chromosomes |
| situation in which an individual has identical alleles for particular trait | homozygous |
| genes not expressed unless they are present in homozygous condition | recessive |
| expression of genetic trait | phenotype |
| situation in which an individual has different alleles making up his genotype for a paticular trait | heterozygous |
| genes for the same trait that may have different expressions | Alleles |
| chromosomes regulating most body characteristics | autosomes |
| the more potent gene allele; masks the expression of the less potent allele | Dominant |
