How are traits inherited?
Vocabulary:
Phenotype: The physical characteristics of an organism
Genotype: the genetic codes an individual carries
Homozygous Dominant: a genotype of TT
Homozygous Recessive: a genotype of tt
Heterozygous: A genotype of Tt
Dominant: a trait that overpowers another; if there is a dominant gene in the genotype, the organisms phenotype will be dominant as well
example: Tt and TT both show a phenotype of tall as a plant
Recessive: a trait that must be present in two copies to show up in the phenotype
example: tt is the only possibility to show the phenotype of short

Label each parent's genotype and put one parent on each side of the square. Then each box inherits the gene from each parent as shown below.
