| Phenotype | Display of a particular version of a genetic trait |
| Diploid, homologous pair | Somatic cells are ______ and those two make up a ________ |
| Maternal and paternal | The homologous pair is one _____ and one _____ |
| Alleles | Different, or changed versions of genes |
| These genes make a population diverse | Allellic variation |
| Mutation | Change in a dna sequence of the gene |
| Homozygous for that gene | Individual who carries two copies of the same allele |
| Heterozygous | Individual whose genotype has two different alleles |
| Dominant and recessive | Allele that exerts control on a phenotype :_____ allele that has no effect on phenotype :_____ |
| Genetic cross | Controlled mating to experiment with inheritance |
| F1 generation | Pgeneration are crossed to produce : |
| F2 gen | F1 gen crossed to make: |
| True-breeding | Individuals with a homogenous genotype |
| Mendels law of segregation | Two copies of a gene are separated during meiosis and end up in different gametes. |
| Dihybrids | Individuals that are heterozygous for two traits. |
| Recombinant phenotypes | Non parental combinations of phenotypes |
| R, r, Y, y : RY, Ry, rY, ry | Combinations of dihybrid produce: |
| Law of independent assortment | States when gametes form, the two copies of any given allele are sorted independently of any two alleles of other genes. |
| Incomplete dominance | When alleles produces an intermediate phenotypein the heterozygote. |
| Codominance | Occurs when the effect of both alleles is equally visible in the phenotype of the heterozygote. |
| Pleiotropy | Situation in which a single gene influences two or more traits |
| Epistasis | Phenotypic effect of the alleles of one gene depends on the presence of certain alleles |
| Polygenic traits | Traits governed by the action of more than one gene |
| Complex traits | Traits that cannot be predicted by laws of inheritance |
