Genetics
Allele
Different forms of genes for a single trait
Pedigree
Family tree
Dominant
Gene that is always expressed
Recessive
Gene that is masked or another words only expressed in the homozygous state
Heterozygous
Genotypes made of two different alleles
Homozygous
Genotypes made up of the same alleles
Codominance
Occurs when both alleles in a heterozygous gene expresses himself fully causing the heterozygous phenotype the show both the dominant and recessive form
Incomplete dominance
Occurs when neither allele in a heterozygous gene expresses itself fully
Gene
Segment of DNA on a chromosome that controls a particular hereditary trait
Genotype
The allele combination for particular trait
Genetics
The field of biology devoted to understanding how characteristics are transmitted from parents to offspring
Phenotype
The outward expression or physical appearance of the gene
Heredity
The transmission of characteristics from parents to offspring
Sex linked trait
Traits found on the X or Y chromosomes
Multiple alleles
When two or more alleles for a trait in the population
