Genetics
When the dominant trait completely takes over and is expressed
Mendelian Genetics/Complete Dominance
the passing of traits from parent to offspring
Heredity
All children are short
tt x tt
The alleles of an individual
Genotype
The color of a red snapdragon crossed with a white snapdragon
Pink due to co-dominance
When the trait expressed is a blend of the 2 alleles
Incomplete Dominance
The physical traits expressed
Phenotype
75% of the children are tall and 25% of the children are short
Tt x Tt
Heterozygous parents
A version of a gene
Allele
If tongue rolling is dominant, RR =
Tongue roller
When dominate traits are both expressed equally
Co-dominace
An organism that has 2 different alleles
Heterozygous/hybrid
All children are tall and heterozygous
TT x tt
gene
The genotype of a person whose mother is short, but they are tall. If tall is dominant to short.
Tt (heterozygous)
