level questions: Inheritance
| Question | Answer |
|---|---|
| Autosomes | 44 non-sex linked chromosomes |
| Autosomal Dominant Alleles | Dominant allele carried on an autosome |
| Pure Breeding | Only possessing homozygous recessive or dominant |
| Sex-Linked Inheritance | Allele carried on one of the sex chromosomes [commonly X since more genes present than Y] |
| Polygenic Inheritance | Phenotypic trait determined by 2 or more genes [Not Mendellian dominant/recessive, contributing allele (T) vs non contributing allele (t) |
| Co-Dominance | Pair of alleles expressed equally in the phenotype of a heterozygous individual [use superscripts] |
| Blood Types | Different groups based on surface glycoprotein [antigen] structure. [A and B are co-dominant, O is recessive] |
| Incomplete Dominance | 2 heterozygous alleles cross to make a new allele by blending [White rose + Red rose = Pink rose] |
