Modes of Inheritance, vocab
| Term | Definition |
|---|---|
| Complete Dominence | Dominant allele masks the effect of a recessive allele in a heterozygous condition Bb |
| Incomplete dominence | Neither allele is dominant, a heterozygous condition results in a blending of allele traits. |
| Co dominence | neither allele is dominant a heterozygous condition in which both allele traits are being expressed |
| Multiple alleles | 3 or more alleles for a trait |
| Sex linked alleles | allele is located on the sex chromosomes. ex XX or XY |
| Heredity | Transfer of biological information from parent to offspring |
| Homologous chromosomes | 2 threadlike structures of the same shape/size that carry genetic information f or specific traits |
| Gene | segment of a chromosome that determines a characteristic or trait |
| Allele | different form of a gene, found on the same position of each homologous chromosome |
| Homozygous | 2 identical alleles for a trait |
| Heterozygous | 2 different alleles for a trait |
| Genotype | pairs of alleles |
| Phenotype | outward expression of the allele pair |
| Gamete | a cell containing 1/2 the amount of chromosomes |
