Did You Study?
| Definition | Term |
|---|---|
| Diagram used to determine the possible traits an offspring can recieve | Punnett Square |
| An Individual's observable traits | Phenotype |
| When a trait is influenced by multiple genes | Epistasis |
| Having Identical alleles in a gene | Homozygous |
| Relationship between 2 versions of a gene | Codominance |
| In Chromosomal DNA, sequences of nucleotides repeated multiple times in a row | Short Tandem Repeats |
| An allele having more than 2 forms within a population | Multiple Allele Systems |
| Bell shaped Curve in a graph | Bell Curve |
| The principle made by Gregor Mendel stating that when 2 or more characteristics are inherited, hereditary factors assort independently during gamete production. | Law of Independent Assortment |
| The heterozygous offspring of a cross of 2 different species | Hybrids |
| Location of a gene on a chromosome | Locus |
| A cross between a homozygous recessive and an individual of unknown genotype | Testcross |
| Effect in which one allele isn't fully dominant to the other, so the heterozygous phenotype is an intermediate blend between 2 homozygous phenotypes | Incomplete Dominance |
| Masks or hides the recessive allele | Dominant |
| Cross between 2 individuals identically heterozygous for two genes | Dihybrid Cross |
| Having 2 different alleles of a gene | Heterozygous |
| The set of alleles held by the chromosomes | Genotype |
| All of the genes on a chromosome | Linkage Group |
| Range of small differences on a shared trait | Continuous Variation |
| The principle made by Gregor Mendel stating that 2 homologous chromosomes end up in different gametes during meiosis | Law of Segregation |
| Cross between 2 individuals identically heterozygous for one gene | Monohybrid Cross |
| Effect in which one gene affects multiple traits | Pleiotropy |
| An Allele that gets hidden or masked by the dominant Allele | Recessive |
