Term | Definition |
---|---|
The passing of traits form one parent to offspring. | Heredity |
The study of how traits are inherited through the actions of alleles. | Genetics |
An offspring that was given different genetic information for a trait form each parent. | Hybrid |
An alternate form that a gene may have for a single trait; can be dominant or recessive. | Alleles |
A too to predict the probability of certain traits in offspring that shows the different ways alleles can combine. | Punnett Square |
Outward physical appearance and behavior of an organism as a result of its genotype. | Phenotype |
The genetic makeup of an organism. | Genotype |
Describes an organism with two different alleles for a trait. | Heterozygous |
Describes an organism with two same alleles for a trait; can be recessive of dominant. | Homozygous |
Production of a phenotype that is intermediate between the two homozygous parents. | Incomplete Dominance |
Occurs when a group of gene pairs act together and produces a specific trait, such as human eye color, skin color, or height. | Polygenic Inheritance |
An allele inherited on a sex chromosome and that can cause human genetic disorders such as color blindness and hemophilia. | Sex-Linked Gene |
A characteristic or attribute of an organism that is expressed by genes and/or influenced by the environment. | Trait |
Biological and chemical methods to change the arrangement of a gene's DNA to improve crop production, produce large volumes of normal functions. | Genetic Engineering |
Describes a trait that is covered over, or dominated, by another form of that trait and seems to disappear. | Recessive |
Describes a trait that covers over, or dominates, another form of that trait. | Dominant |
