- Alternative versions of a gene that produce distinguishable phenotypic effects.
- genotype
- The genetic makeup, or set of alleles, of an organism
- phenotype
- The physical and physiological traits of an organism, that are determined by its genetic makeup.
- dominant allele
- An allele that is fully expressed in the phenotype of a heterozygote.
- recessive allele
- An allele whose phenotypic effect is not observed in a heterozygote.
- Punnett square
- A diagram used in the study of inheritance to show the results of random fertilization in genetic crosses.
- gene
- A discrete unit of hereditary information consisting of a specific nucleotide sequence in DNA (or RNA, in some viruses).
- haploid cell
- A cell containing only one set of chromosomes (n).
- diploid cell
- A cell containing two sets of chromosomes (2n), one set inherited from each parent.
- Gamete
- A cell involved in sexual reproduction and contains only one copy of each chromosome. In mammals it refers to both egg and sperm cells.
- PCR
