|---|---|---|---|---|---|
| allele | an alternative form of a gene
🗑
|
||||
| autosome | A chromosome that is not directly involved in determining gender
🗑
|
||||
| carrier | An individual who is heterozygous for a recessive gene that predisposes for a hereditary disease.
🗑
|
||||
| codominant | phenotypic situation in which both alleles are expressed in the heterozygote.
🗑
|
||||
| crossing over | The exchange of genetic material during prophase I.
🗑
|
||||
| dominant | trait that is expressed when its allele is homozygous or heterozygous.
🗑
|
||||
| F1 generation | resulting immediately from a cross of the first set of parents
🗑
|
||||
| F2 generation | the result of a cross between two F1 individuals
🗑
|
||||
| gene | The genetic information in the chromosomes that determines a trait
🗑
|
||||
| gene mutation | A changed gene. A trait that is not found in the parent.
🗑
|
||||
| genetic variation | Characteristic of an organism that makes it different from the species.
🗑
|
||||
| genetics | The study of the patterns of inheritance of specific traits.
🗑
|
||||
| genotype | The combination of or genes that represent a particular trait.
🗑
|
||||
| heterozygous | Having two different alleles for a specific trait.
🗑
|
||||
| homologous chromosomes | chromosomes that are similar in shape, size, and the genes they carry.
🗑
|
||||
| homozygous | Having two of the same alleles for a specific trait.
🗑
|
||||
| incomplete dominance – | neither allele is dominant; a blending of the two create a new phenotype
🗑
|
||||
| independent assortment | Mendel's second law, stating that each allele pair segregates independently during gamete formation
🗑
