Genetic terms
Question | Answer |
---|---|
This is an alternate form of a gene for a specific trait or gene product | allele |
The alleles for a specific trait are identical (RR, rr) | homozygous |
The alleles for a specific trait are different (Rr) | heterozygous |
This describes the allele that determines the phenotype of an individual organism. (the trait you see-D) | dominant |
The term that describes the allele not expressed when two forms of a gene are present (the trait that is hidden- d) | recessive |
These are the letters that express the genes. Dd | genotype |
The observable characteristics of an organism | phenotype |
An organism that has homozygous genes for a trait - RR rr | purebred |
An organism that has two different genes for a trait - Rr | hybrid |
