Inheritance
| Question | Answer |
|---|---|
| Genes | are unique segments of an organism's DNA that produce a particular functional product. |
| traits | Each functional product of a gene controls a particular aspect of life, and some of these aspects are visible to a careful observer as genetic. Examples include height, eye color, skin color |
| genetic variation | Diversity within a population can be caused by meiosis |
| alleles | This genetic variation is caused by the presence of different |
| In diploid organisms like humans, each individual carries | two copies of each gene |
| These copies can be the same allele or different alleles, depending on the organism’s | parental contributions. |
| The genetic makeup of an organism (set of alleles present) is referred to as its | genotype |
| the visible traits that we can observe as a result of these alleles are its | phenotype. |
| Different alleles for a particular gene locus can be | dominant, or recessive |
| Dominant alleles what recessive alleles | mask |
| recessive alleles, meaning that when a dominant and a recessive allele are both present, the dominant allele's | phenotypic trait is observed. |
| Heterozygous | having two different alleles for a single trait |
| homozygous | has two copies of the same allele. |
| monohybrid crosses | performed to examine the genotypes |
| Codominance | an alternate form of intermediate trait |
| One factor that often becomes apparent in human pedigrees is the presence of a trait that is | sex-linked |
| incompletely dominant | If one allele is what over the other, then a phenotype that is intermediate between the two allelic traits can be observed |
| When the genotype of a parent is not known, a what can be performed | test cross |
| Mendel's Rules of Inheritance can be demonstrated using a | Punnet Square |
| Punnet Square | a diagram that is used to predict an outcome of a particular cross or breeding experiment |
| Recessive Trait | a trait that must be contributed by both parents in order to appear in the offspring |
| Dominant Trait | a trait that will appear in the offspring if one of the parents contributes it |
| Inheritance | A thing that is inherited |
| haploid | Having a single set of unpaired chromosomes |
